I've never seen this before, so i might be way off on my thought here. Could it be that your post is not setup to post arcs? When i generate toolpaths, I need to change the point distribution to 'tolerance and replace arcs' so the post spits out point to point and not arcs, which my control hates. maybe this is the case here???

like I said, I may be way off here and it could be something else entirely. good luck, bonne chance

Genius, your solution works!

However, i have checked the post and it is setup to accept arcs and it works with a different circular toolpath.

huh, strange. glad this work-around helps. maybe a more seasoned post guru will chime in with an explanation.
