Change in actual position vs theoretical

Just had our machine calibrated on 12/6 and I ran an automated probe calibration program late last week. Started crashing on programs that have a tight target window prior to alignment and notice that we have quite a bit of variance between actual hit points versus theoretical targets. X is +.0081, Y is + .00285 and Z is -.0304.
The technician did comment that our calibration sphere was loose and that it was ok to super glue it back into place. I did that this morning and reran the probe calibration probe with no change, still crashing.

Machine Brown & Sharpe one running PCDMIS 2020 R1

any ideas?
Thanks,

You state it is crashing on features prior to Alignment, how is the part being aligned to run DCC held on fixture if so has the fixture alignment been re-run after the calibration.

It is normal practise to remove all fixtures when calibrating a CMM this will then require the fixture alignment program to be run, but even if the fixtures were not removed it is good practise to re-run alignment programs after a machine calibration. This is the first thing I would do to see if it fixes the problem.
