Issue description

When starting up or during processing, the xTool Studio software may display a pop-up indicating abnormal air pump current, preventing processing from continuing.

Different error codes correspond to different causes, and each error code is unique. Please select the corresponding troubleshooting solution based on the error code displayed in the pop-up.

Possible causes

• Air pump malfunction.
• Air pump driver board malfunction.
• UI board malfunction.
• Air tube blockage.
• Abnormal cable connection.

Common error code troubleshooting

AIRPUMP.ELEMENT_ABNORMAL.CUR_HIGH

1. Check the focus position

When the P2S is focused normally, the nozzle is about 4 mm from the material surface.

After processing begins, pause to check the distance between the nozzle and the material surface.

• If the nozzle is pressed against the material, enter the correct material thickness value in the xTool Studio.
• If the distance is normal, proceed to troubleshoot other possible causes.

2. Clean the air path

Follow the tutorial: Clean the tube fittings and the air nozzle

3. Check the UI board

(1) Follow the video to remove the right-side UI board: Assemble & Disassemble the Right Plate for P2S (2) Check whether the air pump connector on the UI board shows any visible abnormalities (such as burnt components). You can also disconnect the J10 connector, power on the machine, and check whether the terminal outputs 24V normally.

• If there are abnormalities such as burnt terminals or incorrect voltage output, replace the UI board.
• If no abnormalities are found, replace the air pump assembly.

AIRPUMP.ELEMENT_ABNORMAL.CUR_LOW

1. Check the air tube connections

Check whether the fittings and air tubes in the laser head air path are properly connected and in good condition.

• If any connection is loose, reinstall by following the cleaning tutorial to prevent air leakage: Clean the tube fittings and the air nozzle
• If the air tube is damaged, replace it.
• If no issues are found, troubleshoot other possible causes.

2. Clean the air path

Follow the tutorial to prevent blockage: Clean the tube fittings and the air nozzle

3. Check the UI board

(1) Follow the video to remove the right-side UI board: Assemble & Disassemble the Right Plate for P2S (2) Check whether the air pump connector on the UI board shows any visible abnormalities (such as burnt components). You can also disconnect the J10 connector, power on the machine, and check whether the terminal outputs 24V normally.

• If there are abnormalities such as burnt terminals or incorrect voltage output, replace the UI board.
• If no abnormalities are found, replace the air pump assembly.

AIRPUMP.ELEMENT_NOT_FOUND

1. Check the air pump cable

(1) Follow this video tutorial to remove the right plate: Assemble & Disassemble the Right Plate for P2S

(2) Check the connection cable on the UI board and air pump adapter board to see whether the socket is loose or the pins on the connection cable are disconnected.

• If the connector is loose, reconnect it properly.
• If any metal pins are broken, replace the corresponding PCBA.

2. Check the UI board pins for short circuits

(1) Disconnect the power supply of the device. (2) Set the multimeter to continuity mode (buzzer mode). (3) Connect one probe of the multimeter to the GND point, and connect the other probe to the 24V, 5V, and 3.3V connectors respectively.

• If any of the circuits is short-circuited, replace the UI board.
• If all three circuits pass the continuity test normally, proceed to troubleshoot other possible causes.

3. Measure the actual voltage of the UI board pins

(1) Disconnect the J10 (the air pump connector on the UI board).

(2) Turn on the device.

(3) Use a multimeter to measure the actual voltage of the 24V, 5V, and 3.3V connectors.

• If the voltage at any point is significantly lower than the expected value, replace the UI board.
• If the measured voltages at all three points are close to the expected values, proceed to troubleshoot other possible causes.

4. Measure the voltage of the J10 pins on the UI board

(1) Disconnect the J10.

(2) Turn on the device.

(3) Use a multimeter to measure the actual voltage of all ports on the J10.

• If the voltage of any pin does not match the values specified in the table, replace the UI board.
• If all voltage values are within the expected range, the UI board is functioning normally. Replace the air pump assembly.

AIRPUMP.ELEMENT_ABNORMAL.TMEP_HIGH

1. Update the firmware

Refer to the following instructions to check the firmware version.

• If the firmware version is "V40.22.006.00" or earlier, it is recommended that you update to the new firmware version 006 or later.
• If the firmware version is already newer than this version, proceed to troubleshoot other possible causes.

2. Test the air pump fan

Disassemble the right plate by following the air pump replacement tutorial (How to Replace the Air Pump for P2S), then check the operating status of the air pump fan.

• Method 1: Visual inspection

The air pump fan operates together with the air pump. During processing, directly observe the fan.

If the fan does not run after processing starts, the fan is abnormal. Record a video and contact customer service to replace the fan or cable.

• Method 2: Command control

Connect the P2S to a computer via USB. Click the command link below to open it in a browser and directly control the fan.

• • If the fan cannot be turned on, replace the fan.
  • If the fan turns on normally, export the device work logs and contact the customer service.

AIRPUMP.ELEMENT_ABNORMAL.STALLED

1. Check the focus position

When the P2S is focused correctly, the distance between the nozzle and the material surface should be approximately 4 mm. You can place a 3 mm basswood sheet in the machine and pause the processing to check the distance.

• If the distance is less than 3 mm, enter the correct material thickness and try processing again.
• If the distance between the nozzle and the material surface is normal, proceed to troubleshoot other possible causes.

2. Clean the air path

Follow the tutorial: Clean the tube fittings and the air nozzle. If the error persists after cleaning, replace the air pump assembly.

Other error code troubleshooting

The following error codes usually indicate an issue with the air pump or its driver board. Replace the air pump assembly (including the air pump and driver board).

• AIRPUMPELEMENT ABNORMAL.FIRST_PEAK_CUR_PROTECT
• AIRPUMP.ELEMENT_ABNORMAL.SECOND_PEAK_CUR_PROTECT
