Using a Mititoyo MiStar 555, can I calibrate a star probe with a normal straight calibration sphere as long as my A and B axis stay at 0.? I understand you need a tilted calibration sphere but thats only if your gonna rotate the head correct?
The Mistar 555 I use and program has a weird issue. Whenever I start learning a new program and I immediately start off in CNC mode and use machine position to find and align the part automatically, when I stop and save and repeat in CMM mode to check and actually run through my program sometimes the position is WAY off from where I programmed. Like .100" or more, causing collisions. Why would this be? Once it picks up an alignment and sets an origin its perfect but in the beginning when its in machine position the repeatability seems way off.
Do I need to actually manually pick up all my alignments everytime? Kinda cumbersome to do so in order to have everyday operators come in and run it. I want them to be able to put the part on the fixture and hit go. Any ideas?
