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!

  • In addition to what everyone else said, double check your probe build and verify you have all the correct components. I've had a very similar issue before and it was because I had built the probe up with the incorrect head and the program thought the ball was 2mm lower than it actually was.
