Having an issue with custom disk probe

When I used 2012, 2016 and 2019, I would qualify the probe manually (MAN, not MAN + DCC) and then run it in DCC (not DCC + DCC).

I would bring the flat on the stylus RIGHT next to the qualification sphere and look at the Z.
Adjust for half the disk thickness AND half the qualification sphere, that gives me the middle of the sphere for THIS probe in THIS qualification.

take hits, watching the Z so I had three circles of four hits each.

The top and bottom circle would be a Z that was just short of half the disk thickness.

I'm assuming you already set the calibration mode to user defined and set a plus minus in degrees as shown int the attached screen shot.

It sucked, but it was the only way I got good qualifications from my disks.

Now, in 2021.2, the disk qualification is AMAZING. If it was always there and I didn't have it on, I'll be angry, but I'm passed that version and not going back, so I did this manual stuff instead.

IF the master probe build is correct, and your custom build is correct, you shouldn't have to do all that, but it's what I did. Take it for what its worth.

good luck
