Hi, RC
I was able to reproduce the issue hear.
If you look into it further, There seem to be an Issue with the Stock Dia, Profile Dia and Posted G-code Diameter, Values.
Final Part should be 2.00 (R 1.00 x 2=2.00), G-code shows ( R 1.3225) or 2.645 Dia., Same as Stock Dir. Shown, I Think.
Pretty, Wild, Nice & Wonderful Program
Thanks, Chip
