I'm going to try a little optical pot, fairly cheap. Under direct control
I only worry for sudden spirts which the steppers may loose counts.
Oh yes, I'm moving two steppers in sync. I
was considering using a VCO and toggle switch. The VCO would
speed up the longer the toggle is held. I guess using an optical pot would
best implimented sending the pulses to a controller instead of directly to the
motor.
It could control acceleration/deacceleleration/max speed.
