Hi Roger - there's a procedure for doing this in the robofocus software - I seem to recall holding down one button when switching the unit on. If you have any slip in the clutch this is bound to end up out if whack. I switch my unit between 3 different motors, so this is an ongoing pain...
Just saw Paul's response - but also seem to recall sometimes during this process the motor stalls...
Cheers,
Andrew.
