Auto Calibration

Here are a few rules about "master probes"

1. if you are using a tp20 (touch trigger), use a large diameter ruby with a short stem like 4x10 or 5x10. If you don't have something these size just use what you have but just make that probe the master probe.
2. If you are suing a LSP scanning head, you can use a 5x20. That is only size that is supposed to be used for the lower matrix calibration so might as well make it the master probe for the probe calibrations.
3. I don't use my master probe for any measurements, I only use it for locating the sphere and calibration. My parameter set just has angle A0B0. Some people have to use their master probe for measurements and that fine. Some people have multiple angles with their master probe and that fine too. You gotta do what you gotta do sometimes.
4. On some of my machines, the cal sphere physically doesn't move from the granite. So when I add an angle to a probe, I update my parameter set for my cal program and calibrate that 1 new angle by answering no, sphere has not moved and everything is good. My other machines however, the sphere has to be moved in and out for parts. So when I need to add a new angle, I have to first place my sphere back where I originally had it, run my master probe with YES DCC, load my probe with new angle, add my angle to the parameter set for my cal program, and then run that new angle. Awesome.
5. You only need 1 master probe. I don't think people have more than one master probe.
6. This doesn't apply to me but some people have to use 2 calibration spheres. I know the procedure is somewhere on the forum, just search for it if you need it or maybe someone will chime in on this thread.
