Re: [CAD_CAM_EDM_DRO] Adjustment

The way I adjust mine is hook the gecko to a function generator, and set it to
about 3 pulses per second. I have to get my ear really close to the motor,
though. But you can _really_ hear the microsteps bunching up (or not bunching
up...). I listen for all the clicks to be about the same volume. If the uSteps
bunch up too much (pot all the way one way) you hear come clicks gradually getting
quieter, and then a "missing" click or two. If the uSteps are un-bunched, then
you hear several uSteps, then one BIG uStep for the motor to catch up.

This way helped me understand what the pot was really for, and just works better
for me.
