Odd issue (which I solved). I have a program that runs an adaptive circle scan on a small arc (20°), which uses clearplanes to hop around the part. No issues with this program, until this update.
I found that the software would just "bypass" the clearplanes, which would cause the probe to run into the part flying at 425mm/s. To add, Path Lines showed the clearplanes to be working. This only happened during actual execution of the program on the physical CMM.

What I found out is that the V9 variable in the X was the culprit WHEN it was an adaptive circle scan. Once I changed it to TTP, the program worked fine. But I want to keep the adaptive circle scan because I don't want to take 11 hits using TTP at 2mm/s touch speed. Slows down the program.
Solution? Plug V9 into a generic feature, align to that, set my X to 0, and it works:

I will submit a Hexagon ticket on this, but I figured I would let Don Ruggieri and the rest of the forum know of my finding in case they have a similar situation.
