Yes, this is very interesting, but I'm still at a loss to understand why there are so many problems going through the speed range just using the foot pedal. My servo motors can all do exactly what is being described just with the foot pedal, but I don't think mine are optical. I guess it has something to do with what you learn on. I learned on machines equipped with clutch motors, so maybe that has something to do with it.
No one lives forever, the trick is creating something that will.
