Now remove the holder from the gripper
again and confirm by pressing 'Enter'.
Now place the adjustment strips (used 
once already) in the gripper. Between
the tips of the strip and the base 
plate there should be a distance of 
approximately 1-2 mm. This enables the
robot body to rotate freely around
axis 1.

When you have centered the strips, this
is concluded with 'Ctrl-Enter'!
