Unable to calibrate 2mm ball probe

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!

  • If you're just hitting "mark all" and saying YES THE SPHERE HAS MOVED, then you're confusing DMIS and not setting up an appropriate master/slave relationship for your probe files. This seems like it might be your problem.
  • I tried all of that stuff and it helped, but still didn't completely fix the issue. I did find a very old backup probe file that I was able to get the calibration to take with. I will definitely be more careful with making sure to not be reckless with my calibration in the future, and with keeping regular backups of probe files.

    Thank you so much!
