Re: HAND WHEEL

Jon,
I think you can have your cake and eat it too.

By setting the resolution on the hand wheel to 0.1 mil, and using a count of 1000 per turn, you will simulate a hand wheel since
one turn gives 0.1" movement and you can pretend it is manual. By changing resolution, you can have 1 or even 10" per turn to
quickly get close and then switch back to high resolution mode.

A 250 count shaft encoder times 4 gives 1000. count.

I think the jog buttons will move the axis continuously, at the step size selected, if held down.
