Find the smallest play by turning the outgoing
shaft for axis 4 in intervals of 90°, totally one
whole turn, and thereby finding the area where
the play for motor 6 becomes smallest.
7
Turn the motor for axis 5 one full turn at the time,
totally five turns. Find the smallest play for axis
6 within this area.
Turn the motor for axis 6 one full turn at a time
for a time for a total of three turns. Find the
smallest play for axis 6 within this area.
Use swift movements to avoid noticing the
magnetic field, which makes the gears stick to-
gether
Push or tap the motor in radial direction so that
the play becomes minimal within one motor turn,
without the gear “chewing”. Do not use force!
