Calibration issue or is this normal...

dmg mori powerprobe 60 optical

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.

Thanks! I know I've seen them before, but never learned about them. Good to know though
