After clicking on 'Home', the faulty axis motor does not rotate. Taking the Z-axis as an example: Normally, after the XY-axis completes homing, the Z-axis should first rise by 10mm, then descend to complete Z-axis homing. If the Z-axis does not move at all after the XY-axis finishes homing, it indicates that the Z-axis motor is not rotating.
Motor wires are not connected properly.
3.1 Reconnect the motor cable of the malfunctioning axis. (The motherboard end also needs to be reconnected.)
3.2 Measure Drive Voltage (Only E-axis measurable), Measure Wire Harness Continuity.Please refer to the tutorial https://www.youtube.com/watch?v=s0PsS8H5PXE
