No Threads to machine

Every cam operation on every part I have with threading is now giving me the "No Threads to Machine" and these are all pre-existing jobs I have used before. I am unable to post any threading operations. any clue why this now no longer works when they worked previously?

 

I have tried deleting the operations and re-creating them with the same error, I have tried changing 'Spun Profile" I have even re-created the part from scratch. I have tried with Modeled threads and without. I am pulling my hair out and need to get this job up and running today HELP

 

They are all lathe parts and using a HAAS post which has NOT changed

I found the issue.

These features are not concentric, there was a modeling issue:

If we set our Rotary axis to the undercut, we get a toolpath:

You fix it by fixing the model or changing which surface you've designated as defining your Z axis.

Why did it work before? Well, it really shouldn't have, since you're working with eccentric features. I suspect we've done stuff in the "Spun Profile" to generate the results you're seeing.
