Issue description

If you encounter a pop-up error message in XCS indicating "W-axis homing failure (error code: M23 S144)" while the indicator light turns red and the buzzer sounds the alarm three times consecutively, this indicates a W-axis reset failure. Please consult this guide for troubleshooting advice.

1. The 34-pin cable on the Z-axis control board may be loose.
2. The 34-pin cable on the main control board may be loose.
3. The motor inside the multi-function carriage may be malfunctioning.
4. The sensor inside the multi-function carriage may be glitching.
5. The multi-function carriage may be breaking down.

Troubleshooting

#2 Reconnect the main control board 34-pin cable

1. Power Down: Turn off the M1 Ultra.
2. Remove Shield: Follow the video tutorial below to remove the main control board shield.
3. Inspect Connection: Ensure the 34-pin cable on the back of the main control board is securely connected.
   • If it is loose, reconnect the cable.
   • Ensure the cable is inserted until the white line is parallel to its connector.

4. Reboot: Reboot the M1 Ultra to check if the machine resumes proper operation.
5. If the error message continues to pop up, proceed to the next step.

#3 Contact xTool Customer Service

1. Power off M1 Ultra.
2. Install either the rotary blade or the cutting blade for testing.
3. Power on M1 Ultra.
4. Observe if the blade tip rotates and evaluate the results:
   • If the blade does not rotate, it suggests a glitch in the W-axis motor inside the carriage.
   • If the blade rotates over one full turn, it indicates a sensor failure.
   • If both actions are normal, the multi-function carriage is likely malfunctioning.

6. Regardless of the above deduction, given the multi-function carriage's structural design, please contact xTool Customer Service for further assistance.
7. Include a detailed description of the issue, your recipient information, and a video of the troubleshooting results in the previous steps to help us determine the appropriate course of action promptly.
