Tip Calibration Process

Smasherofprobes
Hello all, could you please verify that I am calibrating my tips properly! I recently calibrated my machine and my results seem offset in one axis. (Calibration sphere comes off the table after every calibration)

I start by selecting A0B0 only ( Say Yes, Sphere has moved) Calibrate it by itself

Then I Select all tips (Including A0B0) and say No, Sphere has not moved)

The second time I calibrate my tip set should I be including A0B0? Also, Do you guys have a separate probe file called something like "Master probe" with just A0B0? or do you calibrate it within the tip set.

I haven't been on a machine in many years and I'm trying to remember the correct way to do this.

Thanks and my apologies if this is a re-post.

    I've been trying to understand the purpose of the master probe. Being short with a large ball, does it locate the sphere with the best precision possible?

    I believe the purpose of the master is not only to locate the sphere but to also have the least defection as it probes. So a large tip with a short stylus is ideal for touch trigger. I like to use a 5x10 or 4x10 for touch trigger CMMs. I sometimes use a 5x20 for analog heads since that is the probe used for the lower matrix. Not every situation is the same so the best thing to do is to designate a probe as the master probe and only click yes for that probe/tip. All other probes and tip angles need to be answered no.
