Hi I just installed the Z cable extension and the Z servo will only jitter and not turn, I connect the original curly cable to the originally supplied stepper motor cable and things work fine. I then replaced the original cable with the new extension cable all works fine.
I can join the original cable to the “new” extension cable and motor jitters again. When I add the curly cable to the extended pairs the Z axis functions properly.
To be clear in all cases I have used original as supplied Z cable that terminates into the plastic holder on the X rail. The connector on this cable appears to be compliant to the Z stepper motor as it fits, my long winded question is - are the terminations on the Z stepper different to the other stepper motors as I had no problem extending those cables?
