Yeah I thought of that as well, generally I can move the motor slowly, it's a geared stepper motor with 0.072 step angle, so it will move pretty slow whether I'd like or not, but to move it I'll must have it connected, if I could, I'd try thinking of a way to push the shaft back with it being perfectly aligned.
I can probably move the focuser itself slightly, which will move the gears and that way be able to set it properly, or set a very small lever to the middle gear and rotate that which should also result in the same principle I think?
Would that work? Thanks
