Agreed. Seems that the first pass calculation is really good... then it should move way out (to eliminate backlash) and then back to that point.

One additional thing that seems to happen to me... When it currently moves way out, then in, it doesn't wait for the focuser to hit that "out" position. Which means it doesn't always eliminate the backlash. Perhaps you could put a small pause after it moves out... before it moves back in?

Does that make sense?
