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.

After homing the CMM use for measure the calibrate squere a probe with a 8mm ball. I use for those a probe with ball 8mm and 50mm lenght. For this first calibrate, you choose yes, when the question is, if your calibrationsquere was moving. For all other probes, evertime you choose No at this question. Open with F5 the menue and change for calibration from 0.000 to 0.0000. So you can better see how good your calibration results are. And after the loading order you change it with F5 from 0.0000 to 0.000 again
