HEXAGON Probe Head VS RENISHAW

The PH10 cannot rotate to negative A values.

What you are asking, is like asking why, when you go to convert a Blu-Ray disc to VHS, the picture quality doesn't stay the same.  It's simply incompatible hardware.  Frankly, I'm impressed that the software will adapt the 5° increments to the 7.5° increments on its own. 

You would need to comprehensively assess all necessary probe angles currently on your HH-AS6-T5, into probe angle equivalents for the PH10M.  There's no way to automate this conversion.

Any -A values would have to be a positive value (180 out of phase) with B rotating to the same value.

I was looking for any diagram so it will be little easy. T1A-105N-90-> T1A105B90

I know it's noisy but if you image snip the "angle grid" when selecting probe angles, it should serve as effective guidance as to what you are looking for.

Oh... I made a cheat sheet from a polar graph for reversing angles (yes I know its easy) so anyone could do it. 
It had all the +/- rotations listed on the different rings, And a little "probe" that spun around the center.

Super cheesy, but even the shop monkeys didn't ask questions ever again. 
Sadly its at home so I can't send a pic. 

Thats what I am going to do. I asked other operator to send me angles "grid view" of his machine (Global). I believe he have to use -tv polarity in A&B for any angle higher than 90 degrees for A (By looking at fixture and part I assumed A-105, B-90 should be A105, B90). Thanks for great ideas.
