Issue description

When powering on the device or during processing, the software displays a pop-up indicating abnormal air pump current, preventing further processing.

Possible causes

1. Air pump failure
2. Abnormal power supply to the air pump
3. Air pump channel blockage
4. Material thickness issue
5. Fault in the connection cable between the air pump and the UI board
6. UI board failure
7. Air pump driver board failure

Troubleshooting procedure

1. Update software and firmware

• Check if the xTool Studio software and firmware versions are up to date.
• If not, update to the latest versions before using P2.
• If the issue persists, proceed to the next step.]

2. Check the focus status

When xTool P2 focuses normally, the nozzle is approximately 4 mm from the material surface. After processing begins, you can pause to observe the distance between the nozzle and the material surface:

• If the distance is normal, check for other issues.
• If the nozzle is pressed tightly against the material, enter the correct material thickness value in the software.

3. Clean the gas circuit

(1) Power off the device. Refer to the tutorial to remove the three pneumatic connectors and the nozzle on the laser module, then use a thin tool (such as a toothpick or wire) to clean them and ensure there is no blockage.

(2) Use an air gun or similar tool to blow air through the spiral air tube to ensure there is no blockage inside.

4. Test the air pump

(1) Turn off the VPN and connect the device to the computer using a USB cable.

(2) Depending on your computer's operating system, open the air pump startup command below in your browser, and the air pump starts working.

• For Windows: http://201.234.3.1:8080/cnc/cmd?cmd=M15S255&force=1
• For macOS: http://201.234.3.1:8080/cnc/cmd?cmd=M15S0&force=1

(3) Listen to the sound of the air pump while it is operating:

• If the air pump is not working and makes no sound, proceed to the next troubleshooting step.
• If the air pump makes sound but the error still occurs, replace the air pump.

5. Test the voltage of the UI board

(1) Disconnect the power supply, and follow the video tutorial to remove the UI board.

(2) Unplug the cable connecting the air pump and the UI board.

(3) Restart the device. With the air pump running as described in the previous step, use a multimeter to measure the output voltage at the air pump connector on the UI board:

• If the voltage remains stable at around 24V, replace the air pump.
• If the voltage is significantly lower than 24V (typically close to 0V in the event of a fault), please replace the UI board.
