The quill has a return spring , a bit like a pedestal drill but in an exercise the cutting depth is often increasing so backlash wont be a problem there. But lots of exercises where the quill is being driven up and down frequently so lost motion in each direction in that case . I am presuming if you enter a backlash figure , then a number of steps will be discounted before the Display registers movement. Is that so?
