Troubleshooting procedure
#1 Check the air pump and ensure the airflow system's continuity
- Verify Air Pump Wiring:
- Ensure all cables and connectors are securely attached. Refer to steps #1 and #2 in P2S Troubleshooting: Air Pump Current Exception.
- Inspect and clean the air tube:
- Detach the air tube connector from the laser module by pressing it down. (see Image 1, arrow "1")
- Use the 2.0mm hex screwdriver to remove the two screws (see Image 1, arrow "2"), and detach two connectors.
- Clean the air tube connector with a toothpick and reattach it.
- Disassemble the laser lens holder and air tube connector:
- Use a 2.5mm hex screwdriver to remove the two screws (see Image 2, arrow "1").
- Pull down the air tube connector (see Image 2, arrow "2") to remove the lens holder.
- Clean the component:
- Rotate the black retainer counterclockwise to remove the laser lens.
- Place the detached components on a lint-free cloth.
- Clean the laser lens holder outlet and air tube connector with a toothpick.
- Inspect the spiral air tube for kinks or damage.
Note: Use plastic gloves to avoid damaging the lens. Ensure the convex side of the lens faces up during reassembly.
- Reboot your P2S to check if the error message continues to pop up. If this does not settle the problem, proceed to the next step.
#2 Check for bends in the air tube inside the drag chain
- Inspect the entire length of the air tube for bends, kinks, or damage. If there are any issues, replace the air tube to ensure proper airflow and prevent any operational problems.
- For replacing the air tube in the drag chain, please refer to Replace the Cables of the Z-Axis Adapter Board of xTool P2 (while this video does not specifically cover air tube replacement, following the steps will help you learn how to remove and reinstall the air tube).
#3 Test air pump performance
- Activate the air pump via commands: Connect the device to your computer and enter the following commands in a browser:
- Turn on the air pump: http://201.234.3.1:8080/cnc/cmd?cmd=M15S255&force=1
- Turn off the air pump: http://201.234.3.1:8080/cnc/cmd?cmd=M15S0&force=1
You should hear a distinct sound when the air pump starts.
- Check the air pump current value:
- After turning on the air pump, enter the following command to check the airflow value: http://201.234.3.1:8080/cnc/cmd?cmd=M26&dest=34&wait=true&force=1.
- Screenshot the results send them to support@xtool.com with a brief description. If the air pump does not function or the value is too low, the air pump may need to be replaced.
#4 Inspect the UI board and voltage output
- The UI board is inside the upper right cover. You can see it in the aforementioned dissembling video.
- Check the UI board’s air pump socket: Detach the cable and examine the air pump socket (see Image 3, the arrow) for signs of burns or physical damage. If there are unusual signs, the UI board may need to be replaced.
- Measure the terminal voltage (optional): Use a multimeter to check if the output from the air pump socket is 24V. If the voltage is not 24V, the UI board may need to be replaced.
- For a replacement, please contact our customer service team support@xtool.com.
