CMM measuring dimensions incorrectly

Shay**
PC-DMIS 2020R1

I am having an issue with the CMM measuring dims out of tolerance. Screen shot of the CMM report is attached. A lot of these programs are from 2017 or 2018. They are not using CAD models. The CMM was calibrated Aug 2023. I'm very stuck on what else to look into.

I thought maybe it was a migration issue but this is a recent issue. Within the last 8 months.

I tried setting the FCF instead of using the x,y and z from measurements. i tried using the back up program. program is using a star probe so i switched it to a rotating probe, still didn't work.​

    @ Shay**
    it definitely could be an alignment issue.

    have you checked a known standard like a ring gage?
