Tips Calibrated, wrist angles way off?

I have a program that uses T1A0B0, T1A90B0, T1A-90B0 and T1A90B180 and I tried to measure from the front of the part half a cylinder, then rotating to -90B180 and measuring the back half to construct a center axis, but the numbers were way off.

So then I went and re-calibrated and grabbed a gage block and made the attached program. I measured the front plane of the gage block and it related the A0B0 and A-90B0 correctly, but the plane on the back of the gage block using -90B180. It measures Y=76.802 instead of Y=76.200 so off by 0.6mm on the rear plane. Then I did the front plane with A90B180 and it was measuring at -0.3mm. I calibrated all tips and the probe results, are added. Did I forget to calibrate something or is something off with my wrist? Anyone have ideas as to what is going on or what I could have missed?

  • How did you calibrate your probes? Do you have a master? Did you calibrate your master first?
  • Calibrated A0B0 man+DCC then calibrated the rest with a didn't move command. I don't think I set a master, I'll look at how to define and calibrate a master, I don't remember how to do that, it's been a couple years since I programmed, still trying to "get back on the bike".
  • Calibrating master probe is easy. Choose a probe with a short shank preferably 3mmx20mm, when you hit measure tab select YES & take one hit on top of sphere. Then for the rest of probes choose NO. And make sure calibration touch speeds are the same as in the programs.
  • As Matt stated important to do the master probe first, always, also you're Prb Rdv results look out too Disappointed
  • There is something wrong in the hit data after the first alignment the Y axis is not showing the correct nominal, also do not use the minus symbol in names use underscore.

    Whenever the needle is bent, you always get those kind of data from my experience.

    For testing purposes, I would calibrate A0B0 answering yes the sphere has moved to either man or dcc and then calibrate the rest of the tip angles answering NO for each.
