Yes, you are right.
Yesterday was really depressed with stellarmate.
This morning I told myself: do the last test, document it and send a ticket. If nothing works or a new thing appears, buy a MeLE and go back to ASCOM.

Well, thing started by going south: I could not set the sensor in debug mode in INDI. If I press debug it says: "Debug is enabled", and immediately, "Debug is disabled" (WTF!)
I then went to EKOS to exactly document my commands and the focuser response.
In the process, I discovered this AF Overscan thing.
I set AF Overscan to zero and the focuser behaved as expected (!!!???)
Then I set it again to 100 and the problem reapeared:
if I ask an outward movement of 10000 steps from position 8000 it says:That is what expected, but in reality it doesnt move inward 100 steps but 10200 because the focuser ends at 7900 (I can see it physically).

Then I saw your post. Thanks

What the problem is?
Is this a known bug or am I doing something wrong?
