If you cycle the power to the TCF-S, it will perform a homing operation to move the focuser drawtube fully in (position 0), and then move back out to the focuser position as 'remembered' in the TCF-S controller electronics.

Doing this homing procedure can help maintain repeatable positioning of the focuser because it is a Crayford/friction drive...and there can be a small amount of slippage...which is not unusual for a friction drive.
