Avoiding the Bottom of the Sphere during Calibration

With a 1x10mm long probe, seemingly M2 threads going into a 3mm diameter extension?

So the 10mm long section has a large cone at the M2 end of it, and that's where it is shank-hitting? 

If so, you would need to adjust the "End Angle" from 90 degrees to a lower amount, like 70 degrees.  Doing this will make the probe calibrate instead of at the sphere's equator, it calibrates above the equator... preventing the shank-hits.

The shank that is hitting is the extensions before the 1x10 90 degree probe. So it goes too far in when its taking hits on the bottom of the sphere, and the extension collides with the sphere.

In my mind, adjusting the "End Angle" as louisd suggested should eliminate this contact... unless I'm misunderstanding something, which is totally possible!!

You have to be sure your vectors are correct... 

Can you show what vectors you have?

If I remember correctly, the sphere is pointing forward 30 degrees from straight up. I am almost positive my vectors are correct, it's just that because PC-DMIS knows the angle of my sphere, it knows that the sphere is most exposed on the front side. When it calibrates the A0B180 angle for the L PROBE, it goes around the bottom of the sphere, which it does not have clearance to do. I know I can significantly limit my start and end angle but it's only for this angle and the ones close to it and I would prefer to not limit my calibration accuracy.  

If I'm understanding correctly then you have this sort of situation...

You could always re-position / re-orientate the sphere for this problematic tip.  You just need to make sure you use the same "master" tip to define both sphere positions/orientations.
