centers of same feature from 2 different probes - don't match

seppley
About to put in a tech support ticket, but they are slow so.... it is a race to see if you can fix this first.

2mmx30mm probe measure outside cylinder. Then measure the same cylinder with a 4mmX40mm probe. The measured diameters are exactly the same.. but the measured centers are 0.006" different in X and 0.006" different in Y.

this is so not cool, i don't know how long this has been going on or what is causing it. I thought that it was my calibration, so i recalibrated and said "Yes tool has moved" and manually "found" the cal tool just to be on the safe side.... still the same results.

HELP!

  • I use one "master tip" to set the location of the cal sphere at 0A0B. Then after that, all of them are told no, the tool has not moved. I do not believe that it is a calibration proceedural error, i have done plenty of calibrations in my time... and i reinforce that by saying that it is only the one probe that has a problem... all the other probes correlate with each other.

    Yes, same program, same feature, same everything, i just have it go a grab different probes, and it creates mutliple features ontop of each other, then i compare their axis to each other... only the feature created by the 2mm probe is different from the others.
