Replace the stepper with a big larger DC servo and encoder and a Gecko

I built a few motion systems on my former companies dime. I know steppers are cheap but
if you blow past the limits, a servo recloses the loop when it has a chance. Steppers
just sit outside, kicked to the curb, never catching up again.
