You have a zwo eaf?
Overshoot is probably the right mode. And the direction of it matters.
I'm sure I've seen mention of using a much larger backlash setting for this eaf. Just look at you scope when you reverse direction, see how many steps it take for the focuser to start moving - then double that for the setting.
You want more than 2 steps wirhin the flattish part of the curve.
