Over the years, I've randomly (yet persistently) had issues with software tip/probe/head location in Z mismatching with reality. I always calibrate all tips of all assemblies every Monday when I leave for the day.

We recently upgraded to 2020 & I've actually had more issues with this than less. Please see pic 1 for the mismatch. 

Pic 2 shows raises a question about the location the tips are stored. There is no longer a folder "C:\ProgramData\Nikon\CMM-Manager 3.8 SP1\Resource\Tip.tip". 

I'm sure I'm missing something or lacking knowledge, I just don't know what.

All comments & advice are appreciated in advance.
