I see FocusMax 4 has a temperature compensation feature. I was logging the focus positions of my Honders but it was hard to see an accurate difference per degree C. I think it was going in 75 steps out of 105000 on the Atlas. Not 100% sure. The temperature sensor on the Atlas seems slow to respond to the ambient temperature and I think that was throwing it off. Do you use an external temp sensor? That may be the key rather than one embedded in the focuser.
Sky X also has a temp compensation feature. It seems easy enough to use if you get the right temp data.
