Dear Michael,<br>
in the bginning I also had the problem of belt slipping. At least I
was believing that the belt slips. Later I learned that the belt
tesion was to high and the bearing was hard-steering. This results
during the operation of the twister stepping motor in a loss of
steps. Loss of steps or slipping has the same effect, the twister
does not turn to the expected angle. We solved this issue by
exchanging the bearing with a smooth running one and by a LONGER
belt producing lower tension and thereby lower friction in the
bearings of the motor and the sample holder.<br>
<br>
I don't know if this helps to solve your problem but eventually this
could help others. At least here in Munich it worked.<br>
<br>
Best regards<br>
<br>
Hartmann<br>
