Trendsetter_400/800_Proofing
Sets the number of mm the vacuum roller should move away from its home (index
slot) position in order to line up the suction cups tangental to the surface of
the drum.

0 to 300 mm
This is another parameter that's a pain to set up, but the best way to do it is
to load something on the drum, place the vacuum roller in the middle of that
something, then turn on the roller vacuum. After that, jog the stepper 1 mm at
a time in each direction until the vacuum breaks, then the center point of those
two outer limits is the ideal setting for this parameter (type "py pos" to see
the current stepper position). After you think you know the number, reset the
stepper to home ("proof init") and move the stepper to the newly-discovered
postion and see how good it is.
