¶ 4. The Atelier Focusing Lens Is Dirty or Damaged.
Solution:
When there is a significant drop in power or a large change in the laser spot, the laser lens needs to be checked.
-
Dirt/Contamination: first, clean the lens using 99% pure anhydrous ethanol or a professional optical lens cleaner (avoid solvents containing ammonia or acetone). When wiping, use a lint-free cloth and wipe in a single direction (e.g., from the center outward in a spiral), avoiding back-and-forth rubbing that could scratch the lens. After cleaning, inspect the lens under strong side light to ensure no water stains or fibers remain. Please refer to the Atelier laser lens cleaning guide.
-
Damage: if the lens is damaged, the entire laser module must be replaced because it is a sealed structure. The probability of the focusing lens being damaged is very low. Unless there is a significant change in the laser spot, it is not recommended to disassemble the laser to check the focusing lens. Please refer to the Atelier laser replacement guide.
¶ 5. The Atelier Laser Cutting Capability Has Significantly Decreased.
Solution:
-
Normal power attenuation: as the laser is used over time, normal power attenuation will occur. This can be compensated by increasing the power or reducing the cutting speed.
-
Check the fixed focal distance of the laser: refocus the laser using the focusing knob on top of the machine so that the two red dots overlap on the surface of the material. The fixed focal height is 151 mm (distance from the galvo platform to the material surface).
-
Check parameter settings: confirm whether the parameters are correctly set according to the recommended parameter table. Note that the speed unit must be mm/min. How to view the Atelier parameter table: ① scan the QR code on the machine to view it; ② visit the official website: https://atomstack.com/pages/product-support; ③ request it from customer service.
-
Confirm the S-value max setting in the software: if you are using LightBurn, check whether the S-value max has been modified. Make sure it remains at 1000, as this value should not be changed (see Figure 22).
Figure 22 -
Check the sealed glass: check whether the sealed glass at the galvo scanner area is clean, as shown in Figure 23. If there are stains, clean it with alcohol and a lint-free cloth. Please refer to the "Enclosure Cleaning" section for the correct cleaning method. If the glass has stains that cannot be cleaned or if it is damaged, it needs to be replaced. Please refer to the Atelier sealed glass replacement guide.
Figure 23 -
Test the power adapter output: use a multimeter set to DC mode to measure whether the adapter output is 24V. If the output is abnormal, please provide a test video and the device Serial Number and send them to customer service for further handling.
-
Test the laser module status: use 100% power and a speed of 200 mm/min to make one cutting pass on 3 mm plywood to determine whether there is power attenuation. If it does not cut through and there is no visible mark on the back of the plywood, the laser module needs to be checked. Open the top cover of the Atelier and remove the laser module according to the Atelier laser lens cleaning video. Be careful not to let dust enter the galvo scanner assembly.

¶ 7. The Engraving Result on the Atelier Is Distorted.
Solution:
-
Confirm the material weight: lightweight materials can be blown by the strong suction of the Atelier exhaust fan. When engraving lightweight materials, the material should be secured — you can use the provided masking tape to stick it to the base plate or use the supplied positioning strips to hold it down.
-
Confirm that the galvo is calibrated: create a square file in the software and perform an engraving to check whether the result is correct. If distortion is observed, follow the steps below to calibrate in AtomStack Studio or LightBurn.
- Calibration in AtomStack Studio: open the software, click "Settings" → "Calibration" to enter the calibration interface (see Figure 28). Place the engraving material inside the machine and focus it properly. Click "Start" to engrave a 100 mm × 100 mm square. Measure the actual side lengths in the X-axis and Y-axis, then input these values into the "Galvo Calibration" interface in the "size coefficient calculation" section. For example, if the actual square measures 112 mm × 117 mm, input these values to obtain an X-axis ratio of 0.893 (see Figure 29). Repeat the same for the Y-axis. Please refer to the Atelier galvo calibration video.

Check the engraving file: create a square or circular line file in the software and perform a test engraving. If the lines close correctly, the issue is caused by the original engraving file.
-
Check the focus: refocus the laser using the focusing knob on the side top of the laser so that the two red dots overlap on the material surface. The fixed focal height is 151 mm (distance from the galvo platform to the material surface).
-
Check the parameter settings: confirm whether the parameters are correctly set according to the recommended parameter table. Note that the speed unit must be mm/min. How to view the parameter table: ① scan the QR code on the machine to view it; ② visit the official website: https://atomstack.com/pages/product-support; ③ request it from customer service. If the parameter settings are correct, try reducing the speed or increasing the power.
-
Enable "Constant Power": in AtomStack Studio, see Figure 37; in LightBurn, see Figure 38.
Figure 37
Figure 38 -
Increase the $31 minimum power value: use AtomStack Studio or LightBurn to send the command $31=* ("*" represents a specific value; you can gradually increase this value until the lines fully close). For example, if the lines do not close when $31 = 0, send $31 = 10. If the lines are still not closed, continue increasing the value and send $31 = 20, and so on until the lines fully close. For the operation steps, please refer to the Atelier tutorial video on adjusting the minimum power value.
¶ 13. The Atelier Exhaust Performance Is Poor, and the Enclosure Is Filled With Smoke.
