Ah, OK, I see what your doing now, tks!
I think a key, or some kind of physical feature will be required to orientate the spool relative to the end stops.
Maybe on the arm that the motor is mounted to (upper arm) you print a scale, and on the spool you print an arrow.
Home the arms against the end stop, then adjust the location of the spool, repeat a couple of times to verify.
