Calibration issue or is this normal...

That depends on the hardware you're using - stylus, tip, length, material, module, tactile, scanner. Also, depends on if your example is in metric or inches.

Can you provide more info?

I would guess that it is metric, unless he has a 1" diameter tip.

Actually, I think that's the size of the Calibration sphere. Which made me think it would be inches. If I remember right, the calibrations results window only shows the dia of the cal sphere, and not the dia of the tip used.

nope, that SHOULD be the probe as the quad-sphere has no STD-DEV

I do see that the QUALTOOL_ID=25MM, which is equal to ~1" (0.9843)

Yeah this is in inches and you are correct, thats the size of our cal sphere

what probe hardware are you using?

Sure! we are using NC Server 2022.2. Ill take a picture of our probe build which was set up by an applications engineer and looks alot different than what we actually have set up... but according to apps engineer, its correct. I am working in inchs.

I'm not as familiar with the NC side of things, or the specific probe you're using. Are you measuring with the optical, or the touch probe?

if its the touch probe, then this is what I found in the OMP60 manual about repeatability - 

So you should be getting STD DEV closer to that number, depending on actual probe build. Also I would suggest looking into the probe build file that you showed, as its always going to be suggested (and more accurate) to have the probe build match your hardware. (again, I'm not familiar with NC, so maybe that file is want you want)

Beyond that, if you're still having high STD DEV, then here is what the OMP60 manual suggests - 

hope that helps! good luck

He's in a CNC machine so it's an "optical touch probe" where the optical is just referring to the data transmission type. The probe is held in the spindle and communicates with a receiver via IR signals. Pretty cool stuff.
