Troubleshooting errors with automatic probe changing
By Aaron Wilt, Technical Support Specialist
Problem: CMM fails to drop off or pick up a probe from the holder rack during automatic probe changes
in Calypso. The machine may travel to the correct area but doesn’t quite line up with the holder
properly.
Troubleshooting steps:
First, we need to check the alignment of the probe holder rack. The rack should be aligned within
0.1mm from end to end, parallel to a given axis (depends on CMM type and size). Use the CMM to
probe two points on a surface parallel to the aligned axis (X in the example below), but on opposite ends
of the rack. If necessary, loosen the bolts securing the rack to the table and adjust the placement until
the coordinates are within 0.1mm of each other. Once finished adjusting, re-tighten the bolts to secure
the rack and doublecheck the alignment once fixed.
