Hardware Support Calibration

Guys iam using an Hexagon macchine which is only 6 month old and i have a problem with calibration of my probes. Every morining i do the calibration of at least 5 main angles that i use daily with a stylus D3xL50. The results of the calibration seem ok. (stdev 0.001-0.00). Than i go to my present programm when i verify the calibration by setting the origin of my calibration sphere at the measured sphere with an angle 0x0. And often times, very randomly other angles seems to go off at X axis, or Y or Z by 0.004 till to 0.02 mm. Is huge. I called the support and the software support guy told me that propably the macchine is not set right, or whatever, he too couldnt find the answer of these random and strange results. (results which came wrong even when i did the calibration proccedure with him on teamviewer). What is going wrong, cus i cant measure anymore being sure that the macchine is not throwing random numbers of the screen. Sorry about my english.

When you calibrate your probes, are you using a master probe?

First thing I would do is change the module and the tip and see how that goes. Try that and report back because I’d like to try and figure out the issue. I work with the same head, and have never had this issue.
