Error: Internal error - Shoulder radius cannot be below the radius at the top of the tip (the equator on a non tapered tool)

I keep getting the below errors but I'm not sure what the "shoulder radius" is so I'm assuming full radius keycutters aren't supported with blend/flow toolpaths?

Hi, I have an interesting solution for you. I created a new setup4 for myself. To briefly mention, I created a new surface and completed the operation with the ramping command. Details are in the data. The method might be a bit boring but I loved it
