John,

I've not been able to reproduce this at all. When I manually move the focuser in and out using Ekos it behaves perfectly, accurately moving to where I tell it to. For me I really think it's something in the Ekos Hyperbola algorithm. It runs through the moves but at the end rather than choosing the solution, Ekos chooses the last sample as the focus point. It doesn't seem to happen on parabola. You can see this in the screen shots Massimo and I posted. Backlash compensation is disabled in my driver settings and in the firmware.

Thanks
Ken
