Reference video: Kraft laser cleaning video.
Note: If the stains on the protective glass cannot be wiped off or it is damaged, it needs to be replaced in time.
(2) The focusing lens cannot be disassembled. If the focusing mirror is dirty, please wipe it according to the protective glass cleaning method.
If it is damaged, you can only replace the laser.
It is strictly forbidden to try to pry or disassemble it by yourself, otherwise it will damage the laser sealing structure.
If it is damaged and the laser needs to be replaced, please provide the customer service staff with a clear picture of the broken (damaged) protective glass or focusing lens, the machine's serial number (as shown in Figure 14), and the laser laser engraving code (as shown in Figure 15) so that the customer service staff can handle it.

Solution:
(1) Check the focal distance: If you did not refocus after switching to materials of different thicknesses, press the auto-focus button to refocus automatically;
or use the included fixed-focus piece and adjust the knob behind the Z-axis (see figure) to set the focal distance to 40 mm.
(2) Confirm usage duration: Laser modules naturally degrade over time with extended use.
Try increasing the power or reducing the speed to compensate for the loss.
(3) Check software parameter settings: Ensure the engraving parameters set in the software match or are close to the recommended values for the material, as specified in the parameter table.
How to view the Kraft parameter table:
①Enter to view by scanning the QR code on the engraving machine.
②Enter the official website to view [link:https://atomstack.com/pages/product-support].
③Contact customer service staff to request it.
(4) Check the laser mode selected in Kraft: The 1.2W infrared laser has no cutting capability and should not be selected for cutting tasks.
(5) Check S-value max: If you are using LightBurn software, note that the S-value max is fixed at 1000 and cannot be modified (see Figure 16).

Check the power adapter: If the adapter voltage is abnormal, use a multimeter set to the DC voltage range to measure whether the adapter's output is between 20V and 24V (see Figure 17).

(7) Checl the voltage at the laser module connector:
Disconnect the laser connector, then run a cutting program at 100% power and 1 mm/min speed.
Using a multimeter set to the DC voltage range, measure the following:
Between Pin 2 (24V) and Pin 3 (GND), the voltage should be between 20V and 25V.
Between Pin 4 (GND) and Pin 5 (Blue Light PWM), the voltage should be between 1V and 6V.
Refer to the Kraft laser connector voltage measurement video for guidance.
(8) If all of the above checks are normal, the laser module is likely experiencing a power failure and needs to be replaced.
Please provide the full troubleshooting process, the machine's serial number (see Figure 18), and the laser module's laser-engraved code (see Figure 19) to customer service for assistance.
If the measured voltage at the laser connector is below 20V, the issue lies with the motherboard or connection cable.
In that case, please submit a troubleshooting video and the machine's serial number to customer service.
When replacing components, refer to the Kraft laser replacement video, Kraft motherboard replacement video, and Kraft motherboard cable replacement video.

Solution:
(1) Check if the laser is not emitting a laser beam only during the initial seconds:
The infrared laser requires a preheating time of 2–20 seconds.
Ensure that the mode has been switched to Infrared or Dual-laser mode, and allow time for the laser to warm up.
(2) Check the engraving material:
The infrared laser is mainly used for engraving materials like metal and leather.
It does not work on wood and similar materials.
(3) Check the focal distance:
Infrared laser focus is highly sensitive. If you haven’t refocused after changing materials, do so now.
Use auto-focus first and confirm the focal distance is set to 40 mm.
(4) Focal distance verification:
If the focal distance is confirmed to be 40 mm but there's still no visible laser, try this:
Set the power to 20%, press the “Fire” button, then slowly adjust the Z-axis knob or move the material up/down to see if the surface burns or sparks.
If sparks or burning appear at a certain height, that is your effective focal distance.
Continue using it at that height and report the issue to customer service along with:
Your troubleshooting results, the newly found focal distance, your machine's Serial Number (see Figure 18)
Refer to the Kraft infrared laser focus verification video for guidance.
(5) If all checks above are normal, the laser module may be faulty.
Please provide the following to customer service:
A video of your troubleshooting process, the machine’s Serial Number (see Figure 20), the laser module’s engraved code (see Figure 21).
They will assist you with further steps.

Solution:
Check if the motherboard is functioning properly:
In the software, click the Z-axis control buttons (refer to AtomStack Studio in Figure 22 or LightBurn in Figure 23) and observe whether the Z-axis moves up and down according to the commands.
If the Z-axis moves normally in both directions, the motherboard control is functioning correctly.
If the Z-axis can only move in one direction (either up or down), check the Z-axis cable connection:
Ensure the cable is properly inserted.
Inspect the connector for damage, bent pins, or broken pins.
If no issues are found with the cable or connector, the problem is likely due to a faulty motherboard or a defective connection cable.
In that case, replacement of the motherboard or cable is necessary.

(2) Check for issues with the lower limit switch:
While the laser is in standby mode, manually press the trigger block and observe whether the software displays a `limit switch triggered` warning:
● If a trigger warning appears, the issue may lie in the motherboard firmware. Try reflashing the firmware.
If that doesn't resolve the issue, the motherboard may need to be replaced.
Refer to the Kraft Manual Limit Trigger Test Video and Kraft motherboard Firmware Flashing Video for guidance.
● If the trigger block cannot be pressed down (stuck) during inspection, it may be jammed or misaligned.
Adjust it according to the Kraft Lower Limit Trigger Block Adjustment Video.
● If no warning appears after pressing the trigger block, inspect the lower limit switch on the driver board:
Power off the machine, disconnect the laser cable. Remove the laser module by unscrewing the two screws securing the trigger block.
Check if the trigger pin on the driver board’s lower limit switch is damaged.
If damaged, the laser module must be replaced.

(3) Check the motor operation status:
If the motor behaves abnormally during auto-focus—such as erratic movement, unusual noise, or vibration without actual movement—this indicates a motor driver failure on the motherboard or a faulty connection cable.
In this case, the motherboard and connection cable need to be replaced.
Refer to the following videos: Kraft motherboard Replacement and Kraft Cable Replacement.

Solution:
(1) Check if the auto-focus button is faulty:
If pressing the auto-focus button on the engraving machine body produces no response and the software shows no error messages, try triggering auto-focus via software:
In AtomStack Studio, click the auto-focus button(see Figure 24). Or in LightBurn’s console input box, enter the command [ESP500] to see if the machine executes auto-focus (see Figure 25).
If the machine can perform auto-focus via software but not via the physical button, the auto-focus button on the machine is faulty and needs to be replaced.
Refer to the Kraft Auto-Focus Button Replacement Video.
If auto-focus cannot be executed through software either, and the Z-axis does not move at all:
Check the Z-axis motor cable connection for proper insertion, bent or broken pins.
Manually rotate the adjustment knob behind the Z-axis to confirm if it can move up and down smoothly.
If no issues are found with the cable or movement, the problem may lie with the motherboard or its connection cable.

(2) Check if the upper and lower limit switches are faulty:
If the machine can execute the auto-focus command but moves only upward or downward until it hits a mechanical limit and cannot reverse, the issue may be with a limit switch failure.
To test this:
Remove the laser module, then rotate the manual adjustment knob downward to expose the upper limit switch (see Figure 26).
Manually press the upper and lower limit switches (see Figure 27) to see if they can both be triggered.
If the upper limit switch cannot be triggered:
Refer to the Kraft Limit Switch Replacement Video and check whether its connection cable is properly inserted.
Unplug and reconnect the cable. If it still fails to trigger, the switch is likely faulty and needs to be replaced.
If the lower limit switch cannot be triggered:
Refer to the solution titled `During auto-focus, the Kraft laser head touches the material and cannot complete auto-focus.`
For further guidance on testing the switches, see the Kraft motherboard firmware burns into video and Kraft Manual Limit Trigger Test Video.

Solution:
(1) When the software shows a prompt:
Prompt: Disconnected
◆ If the software displays a “disconnected” message:
Check whether the TYPE-C cable was accidentally touched or loosened.
Measure the power adapter output to ensure it is between 23V–24V.
Try using a different USB port on the computer.
Try switching to AtomStack Studio software.
◆ Prompt: Alarm 1
“Alarm 1” means a limit switch was triggered.
Check whether the file size exceeds the working area of the machine.
Frame to see if the movement is normal.
If framing is fine but engraving triggers the alarm, move the file to the center or reduce its size.
Note: The center of the crosshair is the laser firing point, it may not hit the limit during framing, but during actual engraving, the edge of the laser module might come too close and trigger the switch.
If the file is small, centered, and start from absolute coordinates, yet still triggers an alarm, a limit switch fault is likely.
Refer to the Kraft Manual Limit Trigger Test Video for troubleshooting.
(2) When the software shows no prompt:
Unplug and replug the TYPE-C cable, or try a different TYPE-C cable.
Switch between AtomStack Studio and LightBurn software.
Try a different USB port on the computer.
If the problem persists, reflash the firmware. (Note: You cannot flash the same version of the firmware again—use a different version. Contact customer service if needed.)
If the issue continues even after reflashing, the motherboard is likely faulty and needs to be replaced.
Refer to the Kraft motherboard Firmware Flashing Video and Kraft motherboard Replacement Video for guidance.

Solution:
(1) Check that the serial port is not occupied:
Ensure that no other engraving software is currently connected to the Kraft machine.
(2) Confirm the baud rate is set to 460800:
It is recommended to use AtomStack Studio or LightBurn software.
When using AtomStack Studio, no additional setup is needed—connection should occur automatically.
When using LightBurn, you can import the configuration file provided on the included USB drive (see Figure 28).

(3) Confirm the correct COM port is selected:
Open Device Manager and check which COM port corresponds to CH340 (see Figure 29).
If CH340 does not appear or is not recognized, install the USB-to-Serial (CH340) driver.
Try a different TYPE-C cable, switch to another USB port on your computer, or try using a different computer altogether.

(4) Confirm whether you're using a macOS computer:
If you are using a Mac operating system, note that you cannot directly connect the C-end of the TYPE-C cable into the Mac.
You must use a USB hub or docking station to convert the connection to a USB-A port (see Figure 30).

(5) If the above steps do not resolve the issue, try reflashing the firmware.
Note: The same firmware version cannot be flashed repeatedly—you will need a different version.
You can request the appropriate firmware from customer support.
If the problem persists after reflashing, the issue is likely due to a faulty motherboard, which will need to be replaced.
Refer to the Kraft motherboard Firmware Flashing Video and Kraft motherboard Replacement Video for guidance.

Solution：
(1)Verify that the adapter output is normal: use a multimeter set to DC mode to measure the output port of the adapter.
A voltage of 20V to 24V should be present, as shown in Figure 31.

(2) Check whether the power switch is faulty:
First, visually inspect whether the power switch indicator light is on.
If it is on, the device is receiving power normally.
If the light is off, check the accessory connection ports on the motherboard to see if any indicator lights on the motherboard are on.
If the motherboard indicator lights are on, the power switch is functioning properly.
If no lights are on, the issue may lie with the power switch or the motherboard.
Refer to positions 4 and 12 in the Kraft Panel Function Overview for details.
(3) If the above steps reveal no issues, the motherboard is likely faulty and needs to be replaced.
Refer to the Kraft motherboard replacement video for guidance.

Solution：
Confirm the file size: Kraft's working range is 500mm*320mm. If the file size exceeds this range, it will prompt that the travel is exceeded.
Confirm the coordinates used: If the current position is used, it may be that the remaining engraving range of the current position cannot meet the engraving requirements.
It is recommended to patrol the edge first, confirm that the range is met, and then engrave or set it to `Absolute Coords`.
Confirm the limit switch: ◆ Check whether each limit switch is triggered by other objects.
If so, move the triggering object away. ◆ Use software prompts to locate and troubleshoot.
AtomStack Studio software will directly prompt. If LightBurn software is used, you can enter `?`
after the alarm message in the code box to get a prompt (as shown in Figure 32).
Then follow the prompts to troubleshoot. If it can be triggered normally by pressing it manually, you can unplug the limit switch to check whether the prompt continues to trigger.
Confirm the fault and replace it. Refer to the Kraft limit switch replacement video.

If a Z-axis limit switch error is indicated:
Start by checking the upper limit switch. Try unplugging the upper limit switch connector to rule out a fault.
If the issue is confirmed to be with the laser module’s lower limit switch, press the trigger block gently by hand to check whether it moves freely.
If the trigger block is stuck, refer to the Kraft Laser Module Lower Limit Trigger Block Adjustment video to make the necessary adjustments.
If the trigger block moves normally, the laser module likely needs to be replaced.
Please provide the following to customer support for further assistance:
A clear troubleshooting video, the machine’s serial number (see Figure 33), the laser module’s engraved code (see Figure 34)

Solution：
(1) Check whether the speed setting is too high:
Set appropriate parameters according to the reference parameter table.How to view the Kraft parameter table: ①Enter to view by scanning the QR code on the engraving machine.
②Enter the official website to view [link:https://atomstack.com/pages/product-support].
③Contact customer service staff to request it.
(2) Inspect the X and Y axis dual shafts for dirt or damage:
Carefully examine the guide rails and dual shafts to ensure there is no dirt, damage, or other abnormalities.
(3) Identify which axis is malfunctioning:
In the software, create a test file with both a circle and a square outline.
For example, use a cutting mode with a speed of 10,000 mm/min and 30% power to output the lines on plywood.
Observe whether the issue is caused by abnormal movement on one axis or both.
Refer to the Kraft Mechanical Adjustment Video to focus on adjusting the relevant parts.
Important: After each adjustment, perform a test to determine whether the issue improves. If there is improvement, continue fine-tuning.
If not, proceed to adjust other positions.
(4) Check whether the X-axis is parallel to the lower crossbeam:
If the engraved lines are slanted but not wavy or curved, the issue is likely that the X-axis is not parallel to the lower crossbeam.
Adjust the X-axis to ensure it is parallel. Refer to the Kraft Mechanical Adjustment Video for guidance.
(5) Verify whether the step settings have been altered:
In LightBurn or LaserGRBL, open the machine settings and check whether the values for $100 and $101 are set to 100 (see Figure 35).

(6) Confirm that there are no abnormalities in the firmware：try reflashing the firmware(Note: identical firmware versions cannot be reflashed. Please provide your current firmware version to customer support to request an appropriate version.) Refer to the Kraft motherboard firmware burning video.
(7) If all the above steps fail to resolve the issue and structural adjustments have no effect, the motherboard is likely faulty and needs to be replaced.
Refer to the Kraft Motherboard Replacement Video for detailed instructions.

Solution：

(1) Check whether the camera is disabled:
Open Device Manager to see if the camera is restricted or disabled.
If so, remove the restriction and grant the necessary permissions.
(2) Check whether the computer's USB port is damaged:
Try a different USB port on the computer, and use the built-in camera or video app to verify if the image can be displayed.
(3) Check whether the camera cable on the mainboard is loose:
If the camera fails to capture an image, inspect the camera connection cable (see Figure 37).
Use tweezers or a similar tool to carefully unplug and reinsert the cable, then test the camera again.

(4) If none of the above steps resolve the issue, the camera is likely faulty and needs to be replaced.
Refer to the Kraft Camera Replacement Video for instructions.

Solution：
(1) Check whether the coordinate settings are correct:
For camera positioning to work properly, “Start From” should be set to Absolute Coordinates, not Current Position or User Origin.
(2) Ensure the camera is calibrated:
After switching to materials with different thicknesses, recalibration is required.
If the error is too large during calibration, redo the machine model calibration.
(3) Check whether the internal lighting is sufficient:
Inadequate lighting inside the Kraft enclosure may cause significant camera algorithm errors. Improve internal brightness and try again.
(4) Avoid using the edges of the camera view:
It is recommended to perform engraving near the center of the working area.
The closer to the edges, the higher the potential positioning error.

Solution：
(1) Check the lighting conditions of the working environment:
AtomStack Studio has relatively low lighting requirements when using the camera.
However, LightBurn requires significantly better lighting conditions for successful calibration.
If calibration fails, try using external lighting to assist with the process.
(2) Ensure the software has the necessary permissions:
If calibration still fails even with additional lighting, it may be due to insufficient system permissions granted to LightBurn or an issue with the LightBurn software itself.
In such cases, it is recommended to use AtomStack Studio for camera operations instead.

Solution：
Confirm that the factory fixings have been removed: In order to protect the X-axis structure from changes during transportation, we will install a fixing module when it leaves the factory.
After receiving the product, please unscrew the screws of the fixing module and remove the fixing modules at both ends of the X-axis, as shown in Figure 38.

(2) Check whether reverse movement is enabled:
If the abnormal movement is consistent or patterned—such as reversed motion—it may indicate that the Kraft motherboard parameters have been modified.You can check this by going to the machine settings in LightBurn or LaserGRBL（see Figure 39）, Or restore the factory settings in the software or re-burn the firmware.
Note that the same firmware cannot be re-burned. You can contact the customer service staff to request Kraft motherboard firmware burning video.
The method of factory reset is as follows:
◆Restore factory settings in AtomStack Studio:for version 2.20 or later, tap the Version Number (e.g., V.2.20) seven times consecutively to enter Developer Mode (see Figure 40).In the menu, open Serial Port Log, then click Reset to restore factory settings (see Figure 41).

◆in LightBurn software: enter the command $RST=* in the command box to reset to factory defaults (see Figure 42).

(2) Check for damaged or deformed components:
Inspect the timing belts, dual-axis guide rails, and couplings for any looseness, breakage, damage, or deformation.
Also verify that the motor cables are securely connected and that there are no bent or broken pins.
(3) If none of the above steps resolve the issue, try replacing the motherboard, connection cables, and motors.
Refer to the following videos for guidance:
Kraft Motherboard Replacement
Kraft Motor Replacement
Kraft Motherboard Cable Replacement

Solution：
(1) Confirm all operations are normal:
First, check whether the power supply and all connection cables are properly connected, the enclosure door is closed, and whether any limit switches are triggered.
(2) Check for software prompts:
Observe whether the software displays any error messages. If so, follow the guidance to troubleshoot accordingly.
If no message appears, restart the Kraft power supply and the software, then try reconnecting the device.
(3) Check whether other software works properly:
Try switching to AtomStack Studio or LightBurn to test functionality.
If neither software works, try replacing the Type-C cable, using a different USB port, or updating the USB driver.
(4) If the issue persists after all of the above steps, try reflashing the firmware
(Note: identical firmware versions cannot be reflashed. Refer to the Kraft motherboard firmware burning video. Please provide your current firmware version to customer support to obtain a usable version.)
If reflashing the firmware does not solve the issue, the motherboard may be faulty and needs replacement.
Please provide the machine’s serial number (see Figure 43) to customer service for further assistance.

Solution：
(1) Check whether the laser cable is properly connected:
Ensure the laser module's cable is securely plugged in. Unplug and reconnect it to confirm a stable connection.
(2) Verify the software parameter settings:
Check if the settings match the recommended material parameter table.If using LightBurn, confirm whether the S-value Max has been altered.Ensure that S-value Max is set to 1000 (see Figure 44).How to view the Kraft parameter table:
①Enter to view by scanning the QR code on the engraving machine.
②Enter the official website to view [link:https://atomstack.com/pages/product-support].
③Contact customer service staff to request it.

(3) Check whether the focal distance is set to 40mm.
(4) Switch to another laser mode to test functionality:
If the infrared mode is currently in use, try switching to blue laser mode or dual-laser mode to see whether the blue laser functions correctly.
If the blue laser works but the infrared does not, refer to the troubleshooting guide for:
“Blue laser functions normally, infrared does not emit a beam.”
If no mode works, proceed to measure the voltage output of the laser cable:
Unplug the laser cable.
Run a cutting task at 100% power and 10mm/min speed.
Use a multimeter (DC mode) to measure the voltage:
Between Pin 2 and Pin 3, the normal value should be 20V–24V.
Between Pin 4 and Pin 5, the normal value should be 1V–6V. (See Figure 45.)
If the voltage readings are within the normal range, the laser module is faulty and needs to be replaced.
If the voltage is 0V or below the normal range, the issue lies with the motherboard or its connection cables.
Refer to the following videos for detailed instructions:
Kraft Laser Cable Voltage Testing Video
Kraft Motherboard Replacement Video
Kraft Motherboard Cable Replacement Video
Kraft Laser Module Replacement Video

Solution：Check the laser focus:
After changing to materials with different thicknesses, you need to refocus the laser.
Simply press the auto-focus button to complete the process.
You can also manually measure the distance from the bottom edge of the laser module (not the air-assist hood) to the material surface.
It should be 40 mm.
Check the power settings in the software:
If the power setting is too low, try increasing the power or reducing the speed.
Ensure “Constant Power Mode” is enabled:
In AtomStack Studio (see Figure 46) or LightBurn (see Figure 47), make sure the Constant Power Mode is turned on.

Adjust the minimum power value ($31):
If enabling Constant Power Mode doesn’t fix the issue, go to the machine settings in LightBurn or LaserGRBL, and increase the $31 value until the lines appear complete (see Figure 48).
Note: If Constant Power Mode solves the problem, there’s no need to modify $31.

Solution：
Check the laser focus:
If the laser has not been refocused after switching to materials of different thicknesses, the beam may become unfocused and cause wider lines.
Press the auto-focus button to refocus the laser.
Check the protective glass and air-assist hood:
Ensure that the protective glass and air-assist hood are clean and undamaged.
Refer to the Kraft Laser Cleaning Video for inspection and cleaning instructions.
Check the parameter settings:
If the power setting is too high, it can cause the laser beam to widen.
Make sure the settings match the recommended material parameter table, How to view the Kraft parameter table: ①Enter to view by scanning the QR code on the engraving machine.
②Enter the official website to view [link:https://atomstack.com/pages/product-support].
③Contact customer service staff to request it.

Solution：
(1)Check cutting conditions:
Make sure air assist is enabled during cutting.
Verify that the power adapter output voltage is within the normal range (23V–24V).
Ensure the material thickness does not exceed the machine's cutting capability.
(2)Check the laser focus:
After changing to a material with a different thickness, refocus the laser by pressing the auto-focus button.
Inspect the protective glass and air-assist hood:
Make sure the glass and hood are clean and undamaged.
Refer to the Kraft Laser Cleaning Video for proper inspection and cleaning instructions.
(3)Verify software parameter settings:
If the power is too low or the speed too high, the laser may not cut through the material.
Try increasing the power or decreasing the speed.
If using LightBurn, ensure that the S-value Max is set to 1000 and has not been changed (see Figure 49).
How to view the Kraft parameter table:
①Enter to view by scanning the QR code on the engraving machine.
②Enter the official website to view [link:https://atomstack.com/pages/product-support].
③Contact customer service staff to request it.

(4) If there are no abnormalities in the above, it is judged that the laser is faulty and needs to be replaced.
Please provide the customer service staff with the Serial Number (as shown in Figure 50), the fault video (including parameter settings), and the laser engraving code (as shown in Figure 51).

Solution:
(1) Check whether the door opening detection function is enabled:
Verify in AtomStack Studio or the AtomStack App whether this function has been disabled. If so, enable it.
See Figure 52.
(2) Check whether the enclosure door limit switch is faulty:
Manually press and release the enclosure door limit switch to see if the software displays a door open warning.
If no warning appears, the limit switch may be faulty and needs to be replaced.
Refer to the Kraft limit switch replacement video.

Solution：
Measure the voltage at the LED strip connector:
When the machine is powered on normally, the LED light strip should illuminate.
If it does not, use a multimeter set to DC mode to measure the voltage at the LED strip connector.
The normal voltage range should be between 20V and 24V. See Figure 53.

① If the voltage is within the normal range, the LED strip is faulty and needs to be replaced.
Refer to the Kraft LED strip replacement video.
② If the measured voltage is 0V, the LED connection cable is faulty.
Refer to the Kraft LED connection cable replacement video.
③ If the measured voltage is below 20V, the power adapter may be faulty.

Solution:
Confirm that the factory fixings have been removed: In order to protect the X-axis structure from changes during transportation, we will install a fixing module at the factory.
After receiving the product, please unscrew the fixing module screws and remove the fixing modules at both ends of the X-axis, as shown in Figure 54.

Confirm that the step length is correct: Use LightBurn or LaserGRBL to enter the machine settings to check whether the values of $100 and $101 are 100, as shown in Figure 55:

(3) Confirm that the laser is installed correctly: If the Y-axis limit switch triggers normally, but the laser hits the frame, reinstall the laser.
Refer to the Kraft laser replacement video.
(4) Confirm that the X-axis is on the horizontal line: Use a ruler to measure the distance from both ends of the X-axis (the axis where the laser is installed) to the frame to see if they are consistent, as shown in Figure **.
If not, refer to the Kraft X-axis horizontal adjustment video for adjustment.
(5) Confirm the information prompted by the software: If there is a prompt that the maximum stroke has been reached, it is a faulty X-axis or Y-axis limit switch.
Press the limit switch manually (as shown in the Figure 56) to see if a `beep` sound is emitted and the software prompts an information prompt.
If there is no prompt, it is a limit switch fault; if there is a prompt, it is normal.
For replacement, please refer to the Kraft limit switch replacement video.

(6) Confirm whether the X-axis and Y-axis movement are normal: If only one axis can move normally during reset, then you can plug the Y-axis motor cable into the X-axis motor to see if the normal axis and the faulty axis are swapped.
If the same, it is judged to be a motor fault.
If the problem is transferred, it is judged to be a motherboard driver fault or a motor connection cable fault.
Refer to the Kraft motor cable swap video, Kraft motor replacement video, Kraft motherboard replacement video, and Kraft motor cable replacement video.
(7) Confirm the firmware problem: If the above cannot solve the customer's problem, please try to upgrade the firmware.
You can upgrade through AtomStack Studio, AtomStack APP or USB flash drive.
◆Connect to the AtomStack Studio client or mobile app and directly click Update Firmware, as shown in the Figure 57. Note that you will need to insert a USB drive as storage for the update.
◆Copy the file to the root directory of a USB drive and insert it into the USB port on the machine to update.

Solution:
The X-axis limit switch cannot be triggered: In standby mode, manually press the two limit switches on the X-axis (as shown in Figure 58).
◆ If a `beep` sound is heard after pressing and the software has a trigger alarm prompt, then the limit switch itself is normal.
Please carefully check whether there are obstacles blocking the ends or whether the trigger rod is skewed, as shown in Figure 59.
◆ If no prompt is heard after pressing and there is no beep, it may be a limit switch failure.
Please provide a photo of the machine's serial number (as shown in Figure 60) and a video of the failure to trigger to the customer service staff for processing.
For replacement, please refer to the Kraft limit switch replacement video.

The Y-axis limit switch cannot be triggered: In standby mode, manually press the two limit switches on the front and rear of the left Y axis (as shown in Figure 58).
◆ If a `beep` sound is heard after pressing and the software has a trigger alarm prompt, then the limit switch itself is normal.
Please carefully check the following points.
①The laser is not installed properly: remove the laser and reinstall it, making sure the two grooves at the bottom of the laser are aligned with the two limit posts on the slider, as shown in Figure 61.

② The X-axis is not horizontal: measure the distances from both ends of the X-axis to the front frame to see if they are consistent.
If not, refer to the Kraft X-axis horizontal adjustment video.
◆ If no prompt appears after pressing and no beeping sound occurs, it may be a limit switch failure.
Please provide a photo of the machine's serial number and a video of the failure to trigger to the customer service staff for processing.
(3) The Z-axis limit switch cannot be triggered: In standby mode, manually press the Z-axis upper limit switch (as shown in Figure **) and the trigger lever under the laser (as shown in Figure **).
◆ If no `beeping` sound appears when pressing the upper limit switch and there is no alarm prompt on the software, it may be a limit switch failure.
Please carefully check whether the limit switch plug is properly connected.
If it is confirmed that there is no abnormality in the connection line, it may be a limit switch failure.
Please provide a photo of the machine's serial number and a video of the failure to trigger to the customer service staff for processing.
◆If there is no `beep` sound when pressing the lower limit switch and there is no alarm prompt in the software, please unscrew the screws of the flame detection board and check whether the trigger pin of the lower limit switch on the driver board is broken.
If it is broken, please provide a clear photo and a photo of the serial number to the customer service staff for processing.
If it is not broken, please provide a video of the failure to trigger and a photo of the serial number to the customer service staff for processing.
◆If the lower limit switch does not move when pressed, it may be that the trigger rod is stuck.
Please refer to the Kraft laser lower limit trigger rod adjustment video for adjustment.
(4) All limit switches can be manually pressed to issue a prompt but cannot control the movement of the laser: This situation may be caused by an abnormality in the mainboard firmware.
Please provide a video of the failure and a photo of the serial number to the customer service staff for processing.

Solution:
(1) Confirm whether the engraving material is flammable:
Check if the material is flammable, such as MDF. If so, false alarms from the flame detection sensor are more likely.
(2) Confirm whether the engraving file has dense lines:
If the line patterns are very dense, the flame detection is more easily triggered.
It is recommended to increase the engraving speed and the number of passes.
(3) Test whether engraving other materials triggers the alarm:
① If cutting the same file on plywood does not trigger the alarm, you can disable the flame detection function in AtomStack Studio or the AtomStack App while cutting the current material, as shown in Figure 62.
(Note: When this function is disabled, the machine must be supervised at all times to prevent accidents.) Please re-enable this function after engraving is complete.

② If the alarm is still triggered when working on plywood, adjust the flame detection sensitivity in LightBurn or LaserGRBL:
The command $fire_alarm/overflow_value=15 adjusts the number of trigger counts beyond the threshold.
The command $fire_alarm/threshold_value=74 adjusts the flame detection threshold value，shown in Figure 63; a higher value makes it harder to trigger.
Note: While these tips can effectively reduce false alarms, they do not replace careful operation.
Always closely monitor the machine during operation, as safety should be your top priority.

Solution:
(1) Confirm that the air assist is properly turned on:
Check if the control knob is turned on; turning clockwise switches it on.
(2) Check whether the air pump is vibrating:
① If the air pump is not vibrating, measure the voltage at the Kraft air assist power output port (port 05 as described in the panel function section).
The voltage should be between 20V and 24V.
If the power supply is normal, the rotary switch board is faulty and needs to be replaced.
Refer to the Kraft Air Assist Rotary Switch Replacement Video.
If there is no voltage, the mainboard is faulty. Refer to the Kraft Mainboard Replacement Video.
② If the air pump vibrates but there is no airflow, the air pump is faulty and needs to be replaced.
Refer to the Kraft Air Pump and Water Pump Replacement Video.

Solution:
(1) Check if the fire extinguishing water tank has sufficient water:
Inspect the water level through the water level window of the fire extinguishing pump.
(2) Confirm that the active fire suppression function is enabled:
Verify this in AtomStack Studio software or the AtomStack App, as shown in Figure 64.

(3) Confirm that the fire suppression device is receiving power:
If the fire suppression function is triggered but the water pump does not vibrate or make any noise, measure the voltage at the water pump output port on the Kraft chassis.
The voltage should be between 20V and 24V.
If the voltage is present, the water pump is faulty and needs replacement.as shown in Figure 65.

Solution:
(1) Confirm whether an air purifier is being used:
If the purifier’s filtering capability is weak, the exhaust will be affected.
Try removing the exhaust hose and venting the smoke directly outdoors to check if the enclosure exhaust works normally.
If direct venting works, it indicates the purifier’s filtering capacity is weak or the filter needs replacement.
(2) Check if the enclosure fan is clogged with dust:
Excessive dust accumulation will reduce exhaust efficiency. Refer to the Kraft Enclosure Cleaning Video to clean the enclosure and fan.
(3) If direct venting and cleaning do not resolve the issue, the fan may be faulty:
Try replacing the fan. Refer to the Kraft Enclosure Fan Replacement Video.

Solution:
(1) Confirm whether the output pattern is mirrored:
If yes, check if the mirror function is enabled in the software settings. If it is enabled, disable it;
if it is disabled, enable it.
Refer to AtomStack Studio (see Figure 66) and LightBurn (see Figure 67).

(2) Confirm whether the engraving pattern is reversed:
If so, try reversing the motor direction to fix the issue. See Figure 68.

(3)If the above steps do not resolve the issue：Restore factory settings in AtomStack Studio: for version 2.20 or later, tap the Version Number (e.g., V.2.20) seven times consecutively to enter Developer Mode (see Figure 69).In the menu, open Serial Port Log, then click Reset to restore factory settings (see Figure 70).Alternatively, in LightBurn software, enter the command $RST=* in the command box to reset to factory defaults (see Figure 71)

Solution:
Confirm that the connection method is correct: Please refer to the video of unboxing and online use of Kraft.
Confirm the password is correct:The default password for Kraft is 12345678.
Ensure the phone is close enough to the machine:When connecting via the app, keep the phone near the machine.
Check if the machine’s Wi-Fi is occupied:If the machine’s Wi-Fi is already connected to another device, it cannot connect to a new one.
Disconnect other devices before attempting to connect.
Turn off mobile data on the phone and reconnect to Wi-Fi, or try using a different phone.
Confirm the Wi-Fi signal strength of the machine:
When connecting, check the Wi-Fi signal strength on the phone.
If the signal is very weak, the Wi-Fi antenna may be loose.
Open the mainboard, check if the Wi-Fi antenna connector is detached, and reseat it before trying again.

Solution:
(1) Confirm usage conditions:
When using the APP, a USB KEY and a USB drive must be plugged in. The USB drive should have sufficient storage space.
(2) Confirm the enclosure door is closed:
The door must be fully closed to start engraving. The laser will not emit light if the door is open.
(3) Check for any error messages in the APP:
Pay attention to any abnormal prompts in the APP. If there are no messages, try restarting both the engraving machine and the APP.
Also, delete the connected machine from the APP and reconnect it.

Solution:
(1) Check if the USB drive is damaged:
Insert the USB drive into a computer to see if it can be read normally.
If files can be accessed, the USB drive is considered functional.
(2) Confirm the USB drive is plugged into the correct port:
Ensure the USB drive is inserted into the engraving machine’s USB DRIVE port.

Due to the P1's special design, it is not compatible with other brands' modules/accessories. The module uses an 8-pin connector and a specific mounting (see Figure 1).

The P1 does not support other models' modules. It supports the P1's 1.2W infrared module and AtomStack R6 /R8 /R8 Pro rotaries with auto-recognition.

Diode laser: 110 × 110 mm. Infrared laser: 105 × 100 mm. The P1 prioritizes portability.

It can engrave certain metals but cannot cut metal. The P1 supports a diode laser (blue) and a 1.2W infrared laser. See the P1 parameter sheet for settings.
Notes for metal:
• With the diode laser: limited metal marking (e.g., stainless steel with appropriate process), not suitable for metal cutting.
• With the 1.2W infrared laser: suitable for metal engraving; still not for metal cutting.

Available in licensed LightBurn v1.3.01+ or AtomStack Studio. Use parameter tests to quickly find optimal settings for different materials.

The laser window (protective glass) is non-removable. Use 99% anhydrous ethanol or optical-grade lens cleaner (avoid ammonia/acetone). Wipe gently with a lint-free cloth in one direction (e.g., center-out spiral) to prevent scratches. Side-light with a bright source to confirm no residue/fibers remain. Daily cleaning for heavy use; weekly for light use. If the window is damaged, contact support. • Dust buildup on the module fan impairs cooling. Clean weekly (heavy use) or every 1–2 months (light use). Use lint-free cloths or optical swabs (avoid fuzzy cotton swabs).

Use 99% anhydrous ethanol and a lint‑free cloth. Avoid corrosive liquids and avoid back‑and‑forth rubbing that may scratch surfaces. Clean weekly (heavy use) or monthly (light use). After wiping the linear shafts, apply grease evenly (recommend NLGI grade 2 below 15°C; grade 3 above 15°C). When cleaning the exhaust fan, disassemble carefully; do not force. See Fig. 1 for screw locations.

• Store in a dry place; avoid humidity over time.
• Power on the machine periodically to keep electronics in good condition.

• Check panel indicators: solid green = normal; solid red = alarm. If red, confirm the door is closed, head not pressing limit switches, USB key seated, and the door limit switch works. If the door switch is faulty, you may temporarily disable Door Detection in the APP or AtomStack Studio (see Fig. 1) but operate cautiously.
• LightBurn baud rate: 460800 (Fig. 2). Or import the P1 config file.
• Serial/COM port: check Device Manager (plug/unplug Type‑C to see changes). If not recognized or shows warnings, install the USB serial driver. Example COM port shown in Fig. 3.
• Try a different Type‑C cable/port; try AtomStack Studio.

• Check Wi‑Fi signal strength on your phone near the machine. If weak, see “ Wi‑Fi signal is very weak.”
• Ensure no other device is occupying the P1’s Wi‑Fi connection.
• Try alternative modes: Wi‑Fi, Bluetooth, or Hotspot as supported. See APP connection tutorial.

• If dirty: clean with 99% anhydrous ethanol or optical‑grade cleaner (avoid ammonia/acetone). Wipe gently with a lint‑free cloth in one direction. Side‑light to confirm clean. Clean daily (heavy use) or weekly (light use). See window /fan cleaning video.
• If damaged: the window is non‑replaceable; replace the entire module. Provide clear photos of the damage, the machine Serial Number (Fig. 1), and the laser module code (Fig. 2) to support.

Indicator is RED:
• Door closed? Open and re‑close. Check the Hall switch wiring at the door (Fig. 1). Use a small magnet near the Hall sensor—if it turns green (Fig. 2), the door magnet may be weak or the switch/wiring loose. See “Door Detection not working.”
• Head at the edge? Manually move the head to the center to avoid pressing a limit switch.
• Limit switches: press each internal limit switch to confirm it triggers (Fig. 3).
• USB key: gently wiggle to detect intermittent contact. Reseat. If needed, press the USB jack shell slightly inward to improve contact (Fig. 4). Provide a fault video and Serial Number (Fig. 5) to support.
• Firmware: copy the latest (or previous) firmware to the USB drive root; insert and wait for beeps to finish. See firmware tutorial.
• If unresolved: mainboard replacement.

Indicator cycles RED/GREEN with beeps:
• Usually poor USB‑key contact. Reseat or gently press the USB jack (Fig. 6).

No indicator light:
• Power adapter: check the adapter LED. Measure output DC 20–25V (Fig. 7). If <20V, adapter is faulty.
• Power switch: disconnect adapter, open the top lid, short the two power‑switch leads with a wire, reconnect power and test. If it boots, replace the switch (see short‑connect tutorial).
• If still off: mainboard failure; replace the mainboard.

• Check wiring: reseat the Hall switch connector at the door (Fig. 1).

• Confirm the door is fully closed.
• Ensure Door Detection is enabled in AtomStack Studio or the APP (Fig. 2).
• Test the Hall switch with a magnet—if it turns green, the door magnet is weak; replace the magnet. If no response to any magnet, replace the Hall switch board (Fig. 3). Until replaced, you can disable Door Detection via software to continue (operate cautiously).

• Focus: refocus after placing material (see focusing tutorial).
• Flatness: ensure the work surface and material are flat; warping leads to uneven depth.
• Material suitability: only non‑transparent materials engrave properly. Verify compatibility in the P1 parameter sheet.
• Software parameters: start from recommended values; for missing presets, test to find optimal parameters based on similar materials.

• Usage time: diode power naturally decays over time—compensate with higher power or lower speed.
• Refocus for different material thicknesses.
• Power adapter output: verify 20–25V DC (Fig. 1).
• Software: confirm LightBurn S‑Max remains 1000 (Fig. 2). Consult the parameter sheet.
• Window condition: clean or replace module if the window is damaged. If all checks pass but cutting is still weak, the module may have failed. Provide videos, Serial Number (Fig. 3), and module code (Fig. 4) for support and replacement.

• Do not engrave reflective materials unprepared—coat the surface (e.g., black paint) or avoid such materials to prevent damage.
• Power adapter: verify 20–25V DC output (Fig. 1).
• Laser cable: reseat the connector.
• Recognition: AtomStack Studio auto‑detects modules. If framing/engraving reports “no laser installed,” the module or cable may be faulty. Use a multimeter to continuity‑test the cable.
• Cable voltages: while running 100% power at 1 mm/min, measure on the module connector (Fig. 2): pins 1–2 = 20–25V; pins 2–3 = >1–6V. If voltages are normal, the module is faulty—replace it. Provide Serial Number (Fig. 3) and module code (Fig. 4).

• Power adapter: LED on and DC output 20–25V? If mains power is unstable locally, try again or use another 24V 3A adapter.
• Rebooting during jobs may indicate a mainboard or adapter fault.
• “Alarm 1” or out‑of‑bounds without hitting the frame: likely a limit‑switch failure; if it hit the boundary, scale down the job.
• “Disconnected”: may be Type‑C cable/COM/mainboard fault. Try another cable/port and install drivers. If disconnects persist, replace the mainboard.
• No alarm message at all: re‑flash firmware. If still bad, mainboard failure.

• Focus consistency: refocus after material changes.
• Flatness: ensure base plate and material are flat.
• Grain variations: natural grain causes variability—try MDF.
• Window: clean the laser window.
• Mechanical: check motor pulley set‑screws (Fig. 1) and confirm belts sit correctly on idlers (Fig. 2).
• If unresolved, send a video showing settings, material surface, results, plus Serial Number (Fig. 3) to support. [img::https://cdn.shopify.com/s/files/1/0790/2586/4977/files/Fig._1_bb68daf6-95ca-42d9-b57b-ace150c4fc17.png?v=1758881305Fig. 1]

• Parameters: verify against the P1 parameter sheet.
• LightBurn S‑Max: confirm 1000 (Fig. 1).
• Window: clean or replace the module if the window is damaged.
• Adapter voltage: confirm 20–25V (Fig. 2).
• Fill artifacts: if horizontal banding occurs, reduce line interval to ~0.08 mm and use Vertical scanning (AtomStack Studio: Fig. 3; LightBurn: Fig. 4).
• Power decay check: 100% power at 200 mm/min cutting 3 mm plywood in one pass—if it fails, the module may be at end‑of‑life.
• If patterns are irregular, see “Irregular patterns.”

• Jog test: use arrow keys to move axes; if motion is diagonal (45°) or wrong, a motor or driver may be faulty. Swap motor connectors to see if the issue moves—if it moves, mainboard driver is faulty; if not, the motor is faulty.
• Circle & square test: draw vector circle & square.
– If unequal sides but straight lines are fine: steps/mm may have changed. Check LightBurn Machine Settings: $100 and $101 should be 100.270 (Fig.1).
– If wavy/curved lines: adjust mechanics—belt tension, belt in idlers (Fig. 51), X‑axis parallelism, motor pulley set‑screws (Fig.2). If still bad, re‑flash firmware. Provide video, parameter screenshots, and Serial Number (Fig.3).

• Module type: note that the infrared module working volume is 105 × 100 × 50 mm.
• File size: ensure the design fits within the P1 work area.
• Coordinates: remove negative coordinates; restart software and re‑import the file.
• Motion check: engrave a 20 × 20 mm square. If size is off, steps/mm may have changed or the controller is abnormal. In LightBurn Machine Settings, set $100 and $101 to 100.270 (Fig. 1). Re‑flash firmware if needed; otherwise mainboard failure.

• Calibrate the infrared red‑cross cursor first (applicable only to the IR module). See tutorial.
• If still off, enter LightBurn Console and send: $rst=* (Fig. 1), then calibrate the cross cursor again.
• If still off, reset offsets with either:
$aux_red_light/offset_y_mm=0
$aux_red_light/offset_x_mm=0
or [ESP312]/X0/Y0
Then re‑calibrate the cross cursor.

Calibrate the IR red‑cross cursor (only on the IR module). If still misaligned, follow the steps in topic 14.

• Design size: ensure it fits (diode: 110 × 110 mm; IR: 105 × 100 mm).
• Always Frame before engraving. If the frame exceeds boundaries, the job will crash.
• Coordinate mode: with Current Position, always frame first to ensure clearance. With Absolute Coordinates and a file smaller than the work area, crashes are unlikely.
• Module type difference: diode uses the laser spot as (0,0) after homing; IR uses the red‑cross center as (0,0).
• Axis motion: use arrow keys to verify correct motion; if only diagonal motion or alarms occur, reseat motor connectors (Fig. 01).
• Firmware: update to latest via AtomStack Studio/APP. If already latest, try a previous version. If unresolved, consider swapping mainboard and motors. Provide Serial Number and fault video. See firmware, mainboard, and motor replacement tutorials.

The enclosure fan can lift or move very light materials. Use the supplied magnets or weights to secure corners/edges.

• Wi‑Fi antenna: open the top cover and reseat the antenna connector on the mainboard (Fig. 1).
• If still weak, the antenna may be faulty—replace it (see antenna replacement tutorial).
• No Wi‑Fi at all may indicate firmware or mainboard faults. Re‑flash compatible firmware; if still absent, replace the mainboard.

• Motor connectors: reseat.
• Identify the faulty motor by unplugging one motor at a time. Swap connectors to determine if the issue follows the motor (driver issue) or stays with the same motor (motor issue). Replace the faulty part accordingly.

• Limit switches: manually press X and Y limit switches (Fig. 58). If not triggering, reseat connectors; if still bad, replace the switch (see replacement tutorial).
• Axis motion: verify normal motion with arrow keys. If clicking or no motion, see topic 19.
• Firmware: check and update via AtomStack Studio/APP (Fig. 1). Insert a USB drive to update.
• Motor pulleys: tighten the pulley set‑screws on both motors with a 1.5 mm hex key (Fig. 2).
• Factory reset: In AtomStack Studio v2.20+, tap the Version Number 7 times to enter Developer Mode (Fig. 3). Open “Serial Port Log” and click “Reset” (Fig. 4). Or in LightBurn Console, type $RST=* (Fig. 5).

• Focus: refocus with the fixed focus lever correctly.
• Energy: increase power or reduce speed.
• Constant Power: enable Constant Power mode (LightBurn: Fig. 1; AtomStack Studio: Fig. 2).

• Clean the fans as per the enclosure maintenance tutorial.
• If using a purifier: check hose kinks/bends; try venting directly. If direct exhaust is fine, the purifier filter may be saturated—replace filters.
• Replace the enclosure fan if RPM is low after cleaning.

• Linear shafts: if dry, apply lubricant.
• Belts: ensure the timing belts sit in the idler grooves (Fig. 1); misalignment can rub on standoffs. See belt replacement and idler adjustment tutorials.
• Steps/mm: verify LightBurn Machine Settings $100 and $101 are 100.270.
• Motor pulley set‑screws: tighten with a 1.5 mm hex key (Fig. 2).

• Jog direction: if axes move opposite to the on‑screen arrows, toggle the axis invert ($3) in LightBurn Machine Settings (Fig. 1).
• Firmware: re‑flash if parameter edits don’t resolve.
• Software: set rotary parameters, and enable/disable Mirroring as needed (AtomStack Studio: Fig. 2; LightBurn: Fig. 3). If still unresolved, consider replacing mainboard and X/Y motors.

• Test the USB drive in a computer. If not recognized, replace it and request the required files from support.
• If prompted to format, use FAT32.
• If the PC recognizes it and formatting doesn’t help on the P1, the mainboard USB port may be faulty—replace the mainboard.

• Power off the P1; reseat the USB drive and try again.
• If asked to format in PC, choose FAT32.
• If storage is abnormal, replace the USB drive.

• Power‑off Resume: if enabled, the head is locked. Connect via APP or AtomStack Studio and disable “Power‑off Resume” (Fig. 1).
• If still locked after disabling, re‑flash P1 firmware (you cannot flash the same version again; request a different version if needed). If manual movement works only when power is off, the mainboard may be faulty—replace it.

Update directly via AtomStack Studio or the APP (requires a USB drive for storage; see Fig. 1). If it still fails, first confirm the USB drive works on the P1.

• AtomStack Studio: if a new version exists, the app prompts to update. Or go to Settings → Check for updates. You can also download from atomstack.com.
• Firmware: update via AtomStack Studio/APP (requires a USB drive; Fig. 1) or copy the firmware file to the USB root and insert it into the P1.
• APP: download from atomstack.com or in APP go to Profile → Settings → About ATOMSTACK to check for updates.

• Alarm 1 — A limit switch was triggered. If it occurred without physical contact, check each limit switch by manually triggering and reseating connectors to isolate the faulty one.
• Alarm 2 — Soft limits. Check $20 (soft limits) in Machine Settings; disable if necessary (Edit → Machine Settings; see Fig. 1).
• Alarm 3 — Disconnected during operation. Use the console/code output to inspect preceding messages and diagnose.
• Alarm 8 — A limit switch is held active continuously. Reseat or disconnect limit switches one by one to locate the fault.
• Alarm 11 — Tilt alarm. If the machine did not tilt or the control box wasn’t disturbed, it could be a false alarm. Power‑cycle or disable the tilt alarm via the APP/control screen/AtomStack Studio.

(4) Choosing a Type-C cable:
Non-original or charge-only Type-C cables may cause connection failure.
Make sure the cable supports data transfer.

The laser uses a fixed-focus module located on the side bottom of the laser.
The laser is secured using an L-shaped hand screw, making focus adjustment faster and easier.
If the hand screw is blocked by the optical axis, pull the handle outward to rotate it freely.

The Swift laser does not come with an air nozzle, so only the F40 Air Assist is compatible.
The F40 includes dedicated air nozzles for both the 7W and 12W lasers and must be installed manually.

Rotary selection:
The Swift uses threaded risers, so R6, R8, and R8 PRO rotary tools are recommended.
Connect the included USB cable to the Accessory port for automatic recognition.
If using R1, R1 Pro, R2, R3 Pro, R1-B, or R2-B:
You must power off the machine, unplug the Y-axis motor cable, and follow the sequence-connection procedure.
Warning: Ensure the device is completely powered off before disconnecting cables to avoid short circuits.
The default riser feet may not fit first-generation rotary units. Use four objects of equal height to elevate the Swift.
AtomStack Studio configuration:
Select the detected rotary device.
R6 (roller) requires no parameter changes.
R8 (chuck) requires setting the circumference or diameter of the material.
LightBurn configuration:
Set the rotary parameters manually:
Rotary type: Roller for R6, Chuck for R8
Rotary axis: Y-axis
R8 (chuck):
Steps per rotation: fixed at 160mm/rotation
Enter either diameter or circumference
R6 (roller):
Steps per rotation: 50mm/rotation
Roller diameter: 16mm (fixed)
Enter either diameter or circumference

Each laser has a fixed-focus knob.
Turn the knob fully in the direction of the arrow.
When the highest point of the knob touches the material surface, set the laser height and then loosen the knob slightly to complete focusing.
Final focus distance is 4mm.

If the L-shaped screw is blocked, pull the handle outward and rotate it to a different orientation.

Current Position:
Uses the laser’s current location as the starting point. You can manually move the laser to any desired position.
User Origin:
A custom start point set by the user.
Absolute Coordinates:
Uses the home position (0,0) as the origin.
The material’s position on the workspace determines the starting location.

Engraving parameter testing requires:Official LightBurn version 1.3.01 or above, or AtomStack Studio.

Cleaning Accessories:
7W laser module: It has no removable focus lens or window lens, so only the surface of the laser tube’s internal lens needs to be cleaned.
12W laser module: It has both a focus lens and a window lens. You may remove the window lens for cleaning, and also check both lenses for damage.
Cleaning Method:
Use 99% anhydrous ethanol or a professional optical lens cleaner (avoid cleaners containing ammonia or acetone).
Wipe gently with a lint-free cloth in a single direction (e.g., from the center outward in a spiral). Avoid back-and-forth wiping that may cause scratches.
After cleaning, inspect the lens surface under strong side lighting to ensure there is no residue or fiber.
Cleaning Frequency:
High-frequency users: clean once daily.
Low-frequency users: clean once weekly.

Components to Clean: Laser module fan, driver board, and tube heat sink.
Cleaning Method: Start by brushing off surface dust. Then wipe clean with 99% anhydrous ethanol and a lint-free cloth.
Cleaning Frequency: Clean when the fan blades are visibly covered with dust.

Components to Clean: Dust on the Y-axis and X-axis guide rails.
Cleaning Method: Use a soft brush to remove dust and debris from the rails to avoid obstruction during operation.
Cleaning Frequency:
Dusty environments: clean once weekly.
Cleaner environments: clean once monthly.

Reason for Cleaning: Prevent dust from blocking the air pump’s intake, which could cause overheating and damage.

(1) Hurricane can achieve autofocus via the autofocus button on the chassis, by clicking the autofocus button in AtomStack Studio software, or by entering [ESP500] in the code box of LightBurn software. Manual focus can also be achieved using a fixed-focus lens.
(2) If the autofocus focal length is not 8mm:
If the autofocus focal length is not 8mm, you can adjust the autofocus focal length by modifying the code in LightBurn or LaserGRBL software. The default value for the autofocus parameter is 1.5, and the correction value is 1.5 ± the error value, i.e.: When the actual value is greater than 8mm, the correction value is calculated as: 1.5 - (actual measured value - 8).
When the actual value is less than 8mm, the correction value is calculated as: 1.5 + (8 - actual measured value).
In LightBurn 【Console】, enter $autoFocus/depth_max_mm = correction value (1.5 ± error value) and press Enter. For example, if the actual focal length of autofocus is 9mm, then the correction value is 1.5-1=0.5.

Refer to the Hurricane camera application video or instruction manual.

If they are loose or disconnected, plug them back in. If they are broken, please provide clear photos of the broken part and the serial number to customer service for processing.

(5) Verify that the Z-axis limit switch or wiring is functioning correctly: First, carefully check that the wiring is not loose or broken. In standby mode, press the limit switch in the red box to see if it triggers an alarm (including a beeping sound and software prompt). If it doesn't trigger, the limit switch or adapter board may be damaged and needs to be replaced. Refer to the Hurricane limit switch replacement video.

(6) Verify that the Z-axis moves up and down correctly when controlled by the software: Use the direction keys in the software (AtomStack Studio, LightBurn) to control the Z-axis movement and check if it operates normally. If it can only move up but not down, or only down but not up, and there is no obstruction during manual adjustment, the mainboard may be faulty and needs to be replaced. Refer to the Hurricane mainboard replacement video.

(1) Confirm that the automatic focusing touches the material surface: If no material is placed, the trigger rod may not be triggered correctly, leading to focusing errors.
(2) Confirm whether modifying the focus correction value solves the problem: If the automatic focusing focal length (Figure 63) is not 8mm, you can adjust the automatic focusing focal length by modifying the code in LightBurn or LaserGRBL software: The default value for the automatic focusing parameter is 1.5, and the correction value is 1.5 ± error value. The calculation method for the correction value when the actual value is greater than 8mm is: 1.5 - (actual measured value - 8). The calculation method for the correction value when it is less than 8mm is: 1.5 + (8 - actual measured value). In the LightBurn [Console] interface, enter $autoFocus/depth_max_mm=correction value (1.5 ± error value), and then press Enter. For example, if the actual focal length of automatic focusing is 9mm, the correction value is 1.5 - 1 = 0.5. Refer to the "Hurricane Focal Length Adjustment" section.
(3) If none of the above solutions resolve the problem, please send the fault video, the image of the modified focus correction value, and the actual focal length value after focusing to customer service.

(2) Verify that the LED strip is receiving power correctly: Disconnect the terminal at the connector, and use a multimeter in DC voltage mode to measure the voltage across the two pins of the connector. The voltage should be between 20V and 25V. If it is 0V or less than 20V, there is a fault in the LED power cable. Refer to the Hurricane LED power cable replacement video for instructions. If the voltage is normal, the LED strip is faulty and needs to be replaced. Refer to the Hurricane LED strip replacement video.

(1) Verify that the RGB LED strip's connector is properly connected: Remove the three screws on the LED cable protection cover and check if the connector is loose or disconnected. Try unplugging and replugging it.
(2) Check if any of the RGB LED beads are lighting up: If none of them light up, the power cable may be faulty. Refer to the Hurricane RGB power cable replacement video for instructions. If some of the LED beads light up, the RGB LED strip is faulty and needs to be replaced. Refer to the Hurricane RGB LED strip replacement video.

Check the purifier working status: If the purifier’s performance is weak, smoke exhaust will be affected. You can remove the exhaust hose and discharge the smoke directly outdoors to check whether the enclosure exhaust is normal. If direct exhaust works properly, the purifier may have insufficient performance or the filter cartridge needs replacement.
Check that the enclosure fan is free of dust buildup: Excessive dust accumulation will reduce exhaust efficiency. Please refer to the Hurricane Enclosure Cleaning and Maintenance video to clean the enclosure and fan.
If neither direct exhaust nor cleaning resolves the problem, the fan may be faulty. Please provide a clear photo of the Serial Number (see Fig. 1) to customer service, and refer to the Hurricane Enclosure Fan Replacement video.

◆Check that the flame detection function is enabled in the software: In AtomStack Studio software or AtomStack APP, verify whether the “Flame Detection” function is turned on (see Fig. 1).
◆Check the flame detection sensitivity:
In AtomStack Studio or AtomStack APP, reselect the flame detection sensitivity level (three levels: Low, Medium, High) as shown in Figure 68. Alternatively, in LightBurn or LaserGRBL, adjust the flame detection sensitivity via the Console command:
$fire_alarm/overflow_value=15 // Adjusts the number of triggers exceeding the threshold
$fire_alarm/threshold_value=74 // Flame threshold; higher values make triggering harder
(see Fig. 2)
If lowering the threshold to the minimum does not resolve the issue, the flame detection board may be faulty. Please refer to the Hurricane Flame Detection Board Replacement video for replacement.
Note: While these adjustments can be useful, they do not replace careful operation. Always closely monitor the machine during operation; safety should always be your top priority.

◆Confirm that the material is not MDF, balsa, or similar:

◆ Precautions:
Do not use corrosive liquids for cleaning. After wiping, the linear shafts and bearing steel surfaces must be evenly lubricated with grease.

Solution:
Contamination:
First, clean according to the section “Cleaning the Protective Window and Focusing Lens of the Glacier Laser.” If the stain cannot be removed, the protective window glass can be replaced (the machine includes two additional spare protective window glass).
Damage:
If the protective window glass is damaged, it can be replaced (the machine includes two additional spare protective window glass). If the focusing lens is damaged, the entire laser module must be replaced. Therefore, determine the cleaning frequency of the protective window based on usage to avoid damage to the focusing lens caused by contamination or damage to the window.

Solution:
1) Normal power attenuation:
After a period of use, the laser module may experience normal power degradation. This can be compensated by increasing the power or reducing the speed.
2) Check the laser focal distance:
Use a ruler or similar tool to measure the distance between the bottom of the laser module and the material surface. It should be 16 mm or 4 mm.
3) Check the laser power level:
The Glacier laser module supports multiple power levels (refer to the “Glacier Laser Power Switching Guide”). Confirm the cutting capability corresponding to the selected power level based on the parameter table.
4) Check parameter settings:
Verify whether the current parameters match the material according to the parameter table and selected power level. Note that the speed unit is mm/min.
How to access the Glacier parameter table:
① Scan the QR code on the machine body.
② Visit the official website: https://atomstack.com/pages/product-support
③ Contact customer service to request it.
5) Confirm S-value MAX:
When using LightBurn software, ensure that the S-value MAX has not been modified (see Figure 11).

6) Check laser module status:
Cut a 3 mm basswood board at 1200 mm/min speed and 100% power to verify performance.
* If it cuts through in one pass, the power is normal.
* If it cannot cut through, follow the steps below:
◆ Check the laser lens:
Power off the device and remove the laser module. Inspect the protective window glass and focusing lens for contamination or damage.
* For contamination, refer to the “Cleaning the Protective Window and Focusing Lens of the Glacier Laser” section.
* If stains cannot be removed or if there is damage, replace the protective window (two spare pieces are included).
* If the focusing lens is damaged, the entire laser module must be replaced.
Provide clear photos and the laser module’s engraved code (see Figure 12) to customer service for assistance.

◆ Check the laser spot:
If the lens is clean, point the laser at a ceiling or a wall 2–3 meters away and briefly activate it to observe the spot.
Check whether the spot is scattered or abnormal. Take a clear photo of the spot (see Figure 13) and send it to customer service for confirmation. Refer to the “Glacier Laser Spot Inspection” guide.

7) If no issues are found above:
Record a video showing the cutting of a 3 mm basswood board at 1200 mm/min and 100% power, clearly including:

Submit the video along with the laser module’s engraved code to customer service for further support.

Solution:
1) Check the laser wiring:
Power off the machine, unplug the laser cable, and plug it back in to see if it returns to normal.
2) Check software parameter settings:
Set the parameters according to the parameter table. Make sure the “Output” option next to the layer is enabled (it must not be turned off), as shown in Figure 14.

3) Check the laser indicator lights:
Carefully observe whether both indicator lights on top of the laser module are on during engraving or cutting (see Figure 15).

◆ Both lights on:
If both the red and green indicator lights are on, this indicates a failure of the internal laser module (laser diode).
◆ Both lights off:
This indicates a fault with the mainboard or the connection cable.
◆ Only the red light is on:
If only the red light is on and the green light is off, open the laser module housing and unplug the three diode connection cables on the driver board (see Figure 16). Then connect the two water-cooling tubes and run the engraving program to check whether the green indicator light turns on.
* If the green light turns on after unplugging the diode cables, the diode is faulty.
* If it still does not turn on, the issue is with the driver board or the mainboard connection cable.
Please provide a troubleshooting video along with the machine’s Serial Number (see Figure 17) and the laser module’s engraved code (see Figure 18) to customer service for assistance.For replacement procedures (mainboard connection cable, driver board, laser module), refer to the following guides:

5) Reflash the firmware:
Provide the machine’s Serial Number (see Figure 27) to customer service to obtain the correct firmware. Load the firmware using a USB drive and try again.

6) If the issue persists:
The mainboard may need to be replaced.
Please provide your troubleshooting steps, a fault video, and the machine’s Serial Number to customer service for assistance.
Refer to the Glacier mainboard replacement video for guidance.

Solution:
1) Confirm correct laser module installation:
When triggering auto-focus, check whether the bottom of the laser module can reach the material surface.
* If the laser cannot reach the material even when the Z-axis is at its lowest position:
* Manually adjust the Z-axis slider upward to a mid position using the adjustment knob.
* Loosen the laser module mounting screws.
* Move the laser module downward.
* Retighten the mounting screws.
Refer to the Glacier laser installation height adjustment video for guidance.
2) Check whether the Z-axis can move properly:
In AtomStack Studio or LightBurn, use the Z-axis up/down control buttons (see Figures 28 and 29) and observe whether the Z-axis moves in the correct direction.
* If there is abnormal noise and no movement:
* Check whether the motor wiring is properly connected.
* Unplug and reconnect the motor cable to see if the issue is resolved.
* If the issue persists, the mainboard, mainboard connection cable, or Z-axis motor may need to be replaced.
Please record a clear video of the issue and provide it along with the machine’s Serial Number (see Figure 30) to customer service for assistance.
For replacement procedures, refer to:
* Glacier mainboard replacement video
* Glacier mainboard connection cable replacement video
* Glacier Z-axis motor replacement video

3）Check the upper and lower limit switches:
Observe the auto-focus process. If the Z-axis reaches the highest or lowest position and continues moving without reversing or stopping, the issue may be caused by a faulty limit switch.
Manually press the upper limit switch of the Z-axis (see Figure 31) and the lower limit switch on the laser module (see Figure 32) to check whether an alarm is triggered.

◆ No response from the upper limit switch:
* If the trigger lever does not spring back when pressed, the limit switch is defective.
Please provide a short video and the Serial Number to customer service for assistance.
* Unplug and reconnect the limit switch cable.
* If the issue persists after the above steps, replace the mainboard, mainboard connection cable, or Z-axis upper limit switch.
◆ No response from the lower limit switch:
* If the trigger lever does not spring back when pressed, the limit switch is defective.
Please record a fault video and provide the Serial Number to customer service.
* If engraving works normally but the limit switch cannot be triggered:
* Check whether the laser module cable is damaged.
* Unplug the connector at the back of the control box and inspect for bent or broken pins (see Figure 33).
* If no issues are found, the lower limit switch board is likely faulty and should be replaced.
Refer to the Glacier laser module lower limit switch replacement video for instructions.

Solution:
1) Check the machine structure:
◆ X-axis parallelism check:
Use a ruler to measure the distance between both ends of the X-axis and the lower crossbeam. If the distances are inconsistent, the X-axis is not parallel to the frame, which may cause the X-axis support to tilt and increase friction with the Y-axis rails, hindering movement.
◆ Check Y-axis timing belts:
Press the two Y-axis belts with your fingers to check whether they have proper elasticity and tension.
* If they feel loose, loosen the two fixing screws of the belt idler pulley on both sides near the upper crossbeam.
* Pull the idler block to tighten the belt, then retighten the screws (see Figure 34).
◆ If only the X-axis has abnormal movement or noise:
Adjust the eccentric wheels of the X-axis guide rail sliders according to the Glacier structural adjustment video (see Figure 35).
◆ If the friction noise occurs at both ends of the guide shaft:
Ensure that the couplers at the ends of the shaft are not too close to the shaft supports.
* If they are too close, adjust the spacing accordingly (see Figure 36).

2) Check motor wiring:
Unplug and reconnect the motor cables to see if the issue is resolved.
3) Check frame condition:
Carefully inspect the X-axis and Y-axis profiles for deformation, rust, or foreign objects.
* If deformation or rust is found, take clear photos and provide them along with the machine’s Serial Number to customer service for assistance.
* Refer to the Glacier unboxing video for profile replacement instructions.
4) If the issue persists:
Record a fault video and provide it along with the machine’s Serial Number (see Figure 37) to customer service for further support.

Solution:
Confirm the type of distortion:
Engrave a circle and check whether it is fully closed.
◆ Fully closed but appears as an ellipse:
This may be caused by incorrect step settings of the machine.
* First, restore the factory settings through the software.
* In LightBurn or LaserGRBL, go to the machine settings and check whether the values of $100 and $101 are set to 100.
* If not, change both values to 100 (see Figure 38).
◆ Open shapes, misalignment, or wavy lines: These issues may be caused by machine structural problems. Please refer to the following structural adjustment methods.

Check the machine structure:
Refer to the Glacier structure adjustment video.
◆ X-axis parallelism check: Use a ruler to measure whether the distances from both ends of the X-axis to the lower crossbeam are the same, in order to determine whether the X-axis is parallel to the upper and lower crossbeams. If not parallel, the X-axis support frame may tilt, increasing friction with the Y-axis guide rails and hindering movement. The adjustment method is as follows:
-- Required tool: L2.0 hex (Allen) wrench
-- Steps:
Near the lower crossbeam, locate the Y-axis motor and the two linear shafts. Use an L2.0 hex wrench to loosen the set screws of the two shaft couplings on the linear shafts that are farther from the motor (see Figure 39).

② Move the X-axis to the top so that the X-axis cable chain is flush against the upper crossbeam (if the chain cannot stay in place, you can secure it with a string). Then tighten the previously loosened set screws on the shaft couplings.
③ After completing the operation, measure whether the distances from both ends of the X-axis to the upper or lower crossbeam are equal. If not, repeat the above steps.
◆ Check timing pulleys and coupling screws: Use an L2.0 hex (Allen) wrench to check whether the set screws on the couplings and timing pulleys are loose.
◆ Check Y-axis timing belts: Press the two Y-axis timing belts with two fingers to feel whether they have good elasticity and proper tension. If they feel loose, adjustment is required. The method is as follows:
-- Required tool: L2.5 hex (Allen) wrench
-- Steps:
① On the sides of the two Y-axes near the upper crossbeam end, use an L2.5 hex wrench to loosen the two screws on the timing belt tensioner (see Figure 40).

② Pull the timing belt tensioner by hand toward the upper crossbeam to tighten the belt until it has proper tension and elasticity, then tighten the two fixing screws on the tensioner.
③ Apply the same adjustment method to the other Y-axis.
◆ Check X-axis timing belt: Press the X-axis timing belt with two fingers to check whether it has good elasticity and proper tension. If it feels loose, adjustment is required. The method is as follows:
-- Required tools: L2.0 and L3.0 hex (Allen) wrenches
-- Steps:
① Locate the timing belt tensioner at the upper right side of the X-axis (see Figure 41). Use an L2.0 hex wrench to loosen the two set screws on the top.

② Use an L3.0 hex wrench to turn the side screw to tighten or loosen the timing belt.
◆ Check the X-axis guide rail slider: Gently shake the laser module by hand to check for any play. If it wobbles or if the X-axis movement is difficult, the eccentric wheels on the X-axis guide rail slider need to be adjusted.
-- Required tools: L2.0 hex (Allen) wrench, needle-nose pliers or similar tool
-- Steps:
① Loosen the side fixing screws to remove the laser module.
② Turn the Z-axis manual adjustment knob to move the Z-axis slider to the highest position. You will see two circular eccentric wheels (see Figure 42).

③ Use an L2.0 hex wrench to remove the set screws securing the eccentric wheels (see Figure 43).

④ Use needle-nose pliers or a similar tool to insert into the two holes of the eccentric wheel and rotate it for adjustment (clockwise to tighten, counterclockwise to loosen). First loosen it, then gently move the Z-axis by hand to let it naturally align. After that, tighten the eccentric wheel clockwise, and finally reinstall the set screws.
⑤ After reinstalling the screws, move the Z-axis left and right by hand to check whether the movement is smooth, without wobbling or sticking. If any abnormality is found, readjust.
⑥ After adjustment is complete, reinstall the laser module.

Solutions:
1）Check the material:
If the material is flammable (such as MDF, balsa wood, etc.), it may cause false flame alarms. You can disable the flame detection function via the touchscreen, mobile app, or AtomStack Studio software (see Figure 44). When cutting, it is recommended to appropriately increase the cutting speed and use multiple passes when processing thick materials.
Note: After disabling the flame detection function, close supervision by an operator is required.

2）Check the engraving file:
If the processed pattern has very dense lines when the flame alarm is triggered, false alarms may occur. You should increase the speed, increase the number of passes, or disable the flame detection function.
Note: Close supervision by an operator is required during operation.
3）Check the flame detection board:
Perform processing at a lower power level. If the flame alarm is still frequently triggered at low power, the flame detection board may be faulty and should be replaced. Refer to the Glacier flame detection board replacement video for guidance.

Solutions:
1）Check the file size:
The size of the engraving file imported into the software must not exceed Glacier’s working area, and the file must not contain negative coordinates. You can reopen the software and use its drawing tools to create a small test pattern to check whether the issue persists.
2）Check for software issues:
Try connecting and operating the machine using AtomStack Studio to see if the same problem occurs. Make sure to use a licensed version of LightBurn.
3）Verify movement:
Use the directional controls (up, down, left, right) in the software to check whether the movement distance and direction of the engraver are correct. If abnormal movement occurs, carefully inspect whether any cables are damaged and whether the motor connectors are properly plugged in.
4）Restore factory settings:
Perform a factory reset in AtomStack Studio or LightBurn. The steps are as follows:
◆ Factory reset in AtomStack Studio: For version 2.20 and above, tap “Version Number: V2.20” (client version number) seven times consecutively to enter Developer Mode. Return to the menu bar, open “Serial Port Log” (Developer Mode), and click “Reset” to restore factory settings. Refer to the AtomStack Studio factory reset video for guidance.
◆ Factory reset in LightBurn: Enter the command `$RST=*` in the “Console” to restore factory settings (see Figure 45).

Solution:
Adjust the eccentric wheels on the X-axis guide rail slider.

Solutions:
1) Restart the machine: Turn off the power and close the mobile app. Restart both the machine and the app, then try again.
2) Try another phone: Use a different mobile device to test. If the other phone works normally, please provide the phone model and upload the logs to our system (see Figure 48).

3) Check the USB drive: Remove the USB drive from the control box and insert it into a computer to check whether data can be read and written properly.
◆ If data can be read normally: Replace it with another USB drive (32 GB or less) and insert it into the machine’s control box to test. If engraving works normally after replacement, the original USB drive is faulty.
◆ If data cannot be read normally: Format the USB drive on a computer to FAT32, then reinsert it into the control box and test again. If the issue persists, try another USB drive (32 GB or less).
◆ If data can be read normally, but replacing with another USB drive (32 GB or less) still does not resolve the issue, the motherboard USB port may be faulty. Please provide detailed troubleshooting steps, a video, and the machine’s Serial Number (see Figure 49), and send them to customer support for assistance. For motherboard replacement, refer to the Glacier motherboard replacement video.

Solutions:
1) Reconnect the USB key: Turn off the machine, remove the USB key, then reinsert it. Power on the machine and check whether it works normally.
2) Use the spare USB key: Turn off the machine, remove the current USB key, and insert the provided spare USB key to check whether it works properly.
3) If the issue persists with the spare USB key: If the alarm continues, the motherboard may be faulty. Please provide the troubleshooting steps performed, a video of the issue, and the machine’s Serial Number (see Figure 50), and send them to customer support for assistance. For motherboard replacement, refer to the Glacier motherboard replacement video.

Solutions:
Check the “Power-off Resume” function: After connecting via AtomStack Studio or the mobile app, tap the icon in the upper right corner to enter the device information. Check whether the “Power-off Resume” function is enabled (when this function is enabled, the laser head must be moved using the directional controls in the software) (see Figure 51).
If it is enabled, please disable it. After disabling, you will be able to manually move the laser module to the desired engraving position while the machine is powered on.

2) If the “Power-off Resume” function is not enabled and the laser module still cannot be moved by hand after powering on, the motherboard may be faulty. Please provide a video of the issue (the video should include the troubleshooting steps described in item (1)), along with the machine’s Serial Number (see Figure 52), and send them to customer support for assistance. For motherboard replacement, refer to the Glacier motherboard replacement video.

Solutions:
1) Confirm the engraver is running: If the air assist is connected to the AIR ASSIST port on the motherboard, it will only activate during engraving or cutting operations.
2) Check the knob switch: Make sure the air assist knob switch is turned on. Note that rotating the knob clockwise turns on the air assist and adjusts the airflow rate.
3) Check the power supply: Use a DC 24V power supply to power the air assist directly and check whether it can start normally.
If it does not start when powered by the motherboard during engraving or cutting, but can start when powered directly by a DC 24V supply, the issue may be with the motherboard or the air pump power cable. You can use a multimeter to test the continuity of the air pump power cable and send the results to customer support for further assistance.
4) Check the operating status after startup: After starting engraving or supplying power to the air assist separately, turn the knob switch to check whether the air assist vibrates.
◆ No response at all: The knob switch may be faulty. Please send a video of the issue along with the machine’s Serial Number (see Figure 53) to customer support. For replacement, refer to the air assist knob switch replacement video.

◆ Vibration present but no airflow or very weak airflow: The air pump may be faulty and needs to be replaced. Please send a video of the issue along with the machine’s Serial Number to customer support. For replacement, refer to the air assist pump replacement video.

Solution:
If the chiller display screen is damaged, the screen assembly must be replaced. Please provide photos of the packaging, photos of the damage, and the machine’s Serial Number (see Figure 54), and send them to customer support for assistance. For replacement, refer to the Glacier chiller display screen replacement video.

Solution:
This behavior is typically caused by the homing function in LightBurn. Please open “Device Settings”, and under “Other Options”, disable the “Auto-home on startup” function (see Figure 55).

Solution:
Please refer to the Glacier firmware upgrade video.
1) Upgrade via USB drive / TF card: Copy the Glacier firmware file (in .bin format) to the root directory of a USB drive or TF card, then insert it into the control box to perform an automatic upgrade.
