As a precondition the front rail (BUM Beam) has
to be parallel to the X/Y beam.
To check parallelism, do the following steps: Go
to menu System - Calibration - XY gantry /
Calibstation and press to open the camera
window (1).
By means of the top camera, check the Y
coordinate of the left (2) and right (3) fiducial of
the front rail (BUM Beam). A deviation of less
than 0.1 mm is acceptable.
If adjustments are needed, go to chapter
'Mechanical Adjustment Possibilities' on page 3-
11.
