Unable to calibrate 2mm ball probe

mushking
I'm fairly new to running a CMM and I'm having an issue that I'm not sure how to fix. Every time I try to calibrate the 2mm ball probe that I typically use (and have used almost daily for the past couple months), it just refuses to calibrate automatically.

When I say that the sphere I calibrate to hasn't moved, the probe goes off to one side and can't seem to find the sphere. When I say that it has moved, I take my hit on the sphere and the probe either stops short of the sphere or crashes into it. I can get it to calibrate manually, but that isn't really feasible in the long term.

The thing that is especially confusing to me is that using other probes, I don't have any issues calibrating. For some reason, it's just the 2mm ball.

Also, I'm using PC-DMIS version 3.125 on a Brown & Sharpe Xcel 9.12.9.

Any help would be greatly appreciated!

  • 1) Turn everything off and then back on again

    2) Clean everything (scales and all)

    3) Select a tip to be your MASTER. Your 2X20 should work well. Say YES sphere has moved and do the manual point. ONLY CALIBRATE T1A0B0 IN THIS STEP. Because you said yes and only did T1A0B0, it is now your master.

    4) Now calibrate all other probes and make sure you say NO SPHERE HAS NOT MOVED. Now, all of these subsequent calibrations are related back to your master.


    If your machine is calibrated and in good working order AND you followed the above sequence correctly, then you should be good.

    If you're still failing, then F9 the probe and verify that all of the components are correct and match your physical build. If the build is correct and you're still failing, check back.
