This prompt indicates that an exception occurred during the Z-axis homing, which may cause the Z-axis sensor to fail to trigger correctly.
Check the Z-axis sensor: Confirm whether the Z-axis sensor is working properly, and check whether there is damage or fault.
Check the hot bed wiring: Ensure that the hot bed wiring is not pulled or blocked to avoid affecting the trigger of the sensor.
Check the working status of the Z-axis sensor to ensure that it can trigger normally.
Make sure that the wiring of the hot bed is not pulled or disturbed.
If the problem persists, consider replacing the sensor or checking other related components.
