I have this recording to share with you, unfortunately no log but will post one soon.
Focusing test...
I change focus and the focuser goes wrong for some reason, then I click the run-button again and the focuser goes to where I wanted.
Problem solved!
When looking at all the settings for autofocus it seems that there is some settings there that interfere when I just want to manually change the focussetting, so I'm not sure why this is happens but it does, I think the settings for autofocus should affect just autofocus but I can be wrong about that.
In 3.6.5 "AF Overscan" is applied to all focuser moves. I would guess you have it set to 100 ticks in the Mechanics tab. So when you move out it does it as a 2-stage process... firstly it moves out by 10+100 = 110 ticks from 6270 to 6380, then it moves in by 100 ticks to 6280.
If you don't want the 2-stage move then set AF Overscan to zero. You'll need to deal with focuser backlash some other way in this case, of course.
