You can set NINA to " dial out " backlash so that it always comes to a new point from the same direction, so say you have a backlash equivalent to 15 degrees, NINA will move the focuser more than 15 degrees away from the last point then move to it, so the backlash is taken out in the first part of the move.
The people writing NINA introduced that about 6 months ago, not sure where it is but most likely in the equipment setup.
Hope this helps.

Thanks. I have been using the overshoot method with NINA. I measured the focuser backlash with some callipers and got a good estimate of the numerical value to use with NINA. I put in a number times 120 percent so it should be ok. The correct number gives me that sawtooth outcome in NINA autofocus diagram. If I put in a very high number, I can get a V shape but the edges are with HFR's of 10 plus. My current system gives me a HFR of around 4 at max with a generally good outcome of around 2 to 2.5 depending on the camera/filters. My vendor washed his hands of this issue when I thought it was my Sesto Senso V 1 auto focuser but it turned out not to be it. I did manage to keep the Sesto and he refunded me to shut me up.
