Issue description

• After connecting M1 Ultra to xTool Creative Space (XCS), if you see a pop-up error message displaying "Z-axis Homing Failure  (Module on Basic Carriage | Error Code: M23 S142)" while the indicator light turns red and the buzzer sounds the alarm three times consecutively, this indicates a Z-axis reset failure. Please consult this guide for troubleshooting advice.

Possible causes

Troubleshooting

#1 Reconnect the basic carriage ribbon cable

1. Follow the video tutorial below to remove the basic carriage cover (from 0:00 to 1:32).
2. Inspect the connector of the basic carriage on the Z-axis control board for any loose connections.
   
3. Replug the connector and reboot M1 Ultra to check if the machine resumes proper operation.
4. If the error persists, proceed to the next step.

#4 Replace the basic carriage

1. Power on M1 Ultra.
2. Inspect if the basic carriage is tossing up and down during the power-on reset phase.
3. If the basic carriage moves up and down, it indicates a possible broken ribbon cable inside the basic carriage, ruling out a motor malfunction. Please contact xTool Customer Service at support@xtool.com for further assistance. Include a detailed description of the issue, your recipient information, and a list of the troubleshooting results you have already attempted to help us determine the appropriate course of action promptly.
4. If the basic carriage does not move, it suggests that the motor connection wire may be damaged, or the motor itself may be malfunctioning. Please contact xTool Customer Service at support@xtool.com for further assistance. Include a detailed description of the issue, your recipient information, and a list of the troubleshooting results you have already attempted to help us determine the appropriate course of action promptly.
