Hi,
I’m having some strange motor issues where the right hand motor seems to be twitching and stuttering intermittently. When this happens while the machine is running, the right side gantry lags a bit before continuing. It seems to stop after a full reset, but will continue again after a while.
I’ve uploaded a video showing the motor twitch, watching with volume up helps.
Seems to me that you have one of two issues:
Your board is defective / going bad
Your stepper motor is defective / going bad
Could also be the wiring to the stepper.
Pull all the connectors for that motor and re-seat them as a simple check.
Try swapping the two Y stepper connectors on the controller and see if the same motor carries on misbehaving or the problem moves over.
