Datums are off inside programs (All out in same direction)

Hello all,

I seem to be running into a problem with my 2way and 4way checks inside my programs. All of a sudden 2 fixtures in a row are showing an offset on my 4way and 2way 0.5mm in the same direction.
For Example I pick up the tooling balls come back check 2 way and 4way and both fixtures show they are out 0.5 mm in same direction (Machine axis). Does this make any sense ? could it be a bent probe that could be causing this issue ? I'm not sure whats going on here. Disappointed

  • Alignments are run inside programs, not recalled. I think the issue is stemming from a calibration issue. I am also running 120mm in extensions on this TP20 so apparently that is not optimal either. My company currently has no QE or QC and the manager here isn't familiar with the CMM unfortunately so im stuck doing all the thinking or lack of Slight smile Thanks guys
