I am having an odd problem with my Robofocus set up to do with the recorded position of the focuser. The autofocus function is working fine but what I am finding is that the step count position of the focuser does not return to its previous position from one imaging session to the next. For example, I may start an imaging session for the night with the focuser at a position count of 2100 at a temp of 600 (robo focus funky units). During the night the step count may drop to 2025 at a temp of 580 funky units. Now, you would expect that the next time out the position would return to 2100 if the temp is back to 600 but it doesn't. It always starts off at the same position that it was in the previous night.(2025 in my example here). Every night I go out then the position count gets lower and lower until I have to reset the zero position. The physical focus point on the OTA is not changing much however (I drew a line on the draw tube so that I can see where it was changing).
Any ideas?
Thanks,
Rodney.
