you'll need to be able to do some type of spiral pocketing. I think my software has it. I'll have to go crank it up and look in a few.

The ai is tricky to prompt to get results. Because it is actually a "Morph Spiral". Not just a standard pocket or boundary pocket

Here is me attempting to get results with your file

Started with to proper path

then tried to get more "revolutions"

Finally made it all the way to center with revolutions and lost ability to control step

Its getting complex
