Hi John,

I finally got around to updating my focuser to the latest firmware. Backlash compensation is disabled. I tried several steps in and out and the focuser hardware appears to be very repeatable. Unfortunately, I'm still seeing the issue. Here's a screenshot from tonight's testing. The correct solution is 10185 which I confirmed with a bahtinov mask but the algorithm picked 10084 for some reason which is out of focus. I haven't spent much time with the other Curve Fit settings but it does seem like the Hyperbolic fitting causes me the most trouble.
