See pic;- every time one of those "teeth" passes a "notch" in the core of the coil you generate a voltage spike (which can actually be quite a...
I use mine for a cnc router, so I don't know all the answers for your application, but have a look at the Duet controller which has 5 stepper...
DRY ptfe or silicone spray for the leadscrew. Alex.
Most likely you have disturbed one of the wire connections to the stepper motor that is misbehaving. POWER OFF and check all the connections. Alex.
PS - someone has developed a modification of the Ooznest interface for the Duet 3 - I'll try to find a link tomorrow if you are interested. Alex.
