OK, I'm glad you solved that part of it. What type of breakout board is this?

I'm not sure what kind of sugestions you are looking for.... The numbers doesn't mean anything to me since I don't know you steps/inch, gearing, leadscrew pitch, maximum motor speed etc.

If you have 60ipm set up in motortuning it doesn't matter if you go above 100% feed, it won't go faster than 60ipm...
