General Mach Discussion / Re: Possible to send pulses directly to stepper driver while connected to a BOB

Just rambling…
It’s probably way OTT for your application but I had a similar situation a while back and after much experimentation and thought settled on a system of using two stepper motors driving one axis through a differential gear arrangement. One motor (controlled by Mach) did all the work of driving the axis and the other motor (controlled by a plc driven by sensors) made the corrections.
Just something to think about, perhaps ?
Tweakie.
