@Ken5 have you tried updating your post processor file in the Vectric software?
Go to the search for machine online menu option, and it will locate an updated post processor configuration where you can select rotary (see photo).
The new post processors are named Masso ATC Arcs (see photo).
Let me know if this helps out at all.
I have my rotary setup now but have not had a chance to run a test file yet.
Good luck.
