Issue description

When you use laser processing, the laser module does not emit a laser. At this point, if you observe the laser tube from the primary mirror, it does not illuminate during processing.

The image below shows the laser tube in its normal illuminated state during processing.

If the laser tube lights up during processing but without emitting a laser, go to Troubleshoot No Laser Output for xTool P3 for troubleshooting procedures.

Possible causes

1. Power is set too low.
2. Laser tube is faulty.
3. Connection cable of the laser power supply is loose.
4. Power supply of the laser tube is faulty.

Troubleshooting procedure

1. Check the laser power setting

Check whether the processing power is too low. If it is too low, the laser tube can't emit the laser. As the laser tube ages, more power will be needed for the same level of laser activation as before (normally, the power is within 20%). Please try to process the material by increasing the power by over 20%.

2. Check the laser tube

(1) Disconnect the power supply of the device.

(2) Remove the rear upper cover by referring to the video tutorial. The laser tube is not required to be removed.

(3) Inspect the laser tube for any cracks, both inside and outside.

• If any cracks are found, replace the tube.
• If no crack is found, check for other issues.

3. Check the connector of the main control board

(1) Disconnect the power supply of the device and remove the left plate. See the video or follow the tutorial below.

(2) Check whether there is any looseness in the cable connector as shown.

• If it is loose, plug it snugly.
• If it is not loose, check for other issues.

4. Check the connector of the laser power supply

(1) Disconnect the power supply of the device and remove the right plate. See the video or follow the tutorial below.

(2) Check whether there is any looseness in the cable connectors as shown.

• If they are loose, plug them snugly.
• If they are not loose, check for other issues.

5. Check the laser power supply

(1) Based on Step 4, power on the device and process at 50% power (a file lasting several seconds will suffice).

(2) Observe whether the indicator (as shown) on the laser power supply lights up normally during processing.

• If the indicator lights up, replace the laser tube.
• If the indicator won't light up, replace the power supply of the laser tube. And take a picture of the QR code on the laser power supply and send it to xTool customer service team.
