Calibration Fail

[GunLake]

Hello,

So every few days (I don't use the CMM often) I calibrate using the sphere, Never had an issue in the past but lately my A0,B0 position will fail. Everything else is good. If I redo it a few times it will eventually pass. Is this a sign of the tip going bad?

Thank You,

Several things it COULD be.

Dirty TP20 module base (use the "silly putty" stuff to clean the contacts, on the module & base unit)
Crash causing the module to get 'shifted', easy to fix, put the module on the table (connecting base DOWN) and press unit into table. This will re-seat the unit, but expect to have to replace it eventually, they are not meant to be 'fixed' like this, but generally it will work.
Dirty sphere or tip
Loose tip (or even loose sphere)
******* tip

When you say fail, what do you mean. Std Dev, diameter?

Press the TP20 down into the table to ensure the balls are properly seated into into the unit. If they're un-seated, you might feel a slight "click" as it pops back into place.

Clean everything.

Visually inspect that nothing is damaged.

Make sure the probe info is correct.

Re-start CMM and controller. Allow it to "Home" itself. Then, attempt to qualify using your MASTER probe.

This is the stuff you should look at first.. Report back if you still have issues.

Agreed ^^^
Also look at your ruby. I racked by brain for hours once and realized there was a tiny pin sized chip in my ruby that was causing the failure
