Solved 4 Z motors.. one randomly goes weird

[Adamfilip]

I have 4 steppers on my Z. (voron style) and One of them is acting strangely. hours into a print it will glitch and move the opposite direction from the rest. and the connector on the Duet2wifi feels very warm, much warmer then the others and started being noisy.

I assume I need to replace the wires/connector
could the stepper itself be bad?

@Adamfilip post config, and all the motors the same type?

@Adamfilip try switching the motor to another port and see if the problem follows the motor or stays with the driver

@T3P3Tony I swapped the motor for another. unsure if it was the Wires/Connection or motor itself and it solved the problem.
