I don't quite understand what you are trying to cut, but my choices
are 1) DeskCNC for 3D rotary .stl and 2) Vector Cad-Cam for 3D
rotary, vector cutting.

There is a 30 day full working demo of Vector Cad-cam that can turn
flat geometry and flat toolpaths into 3D rotary contours adn
toolpaths, including creation of X-Z-A g-code to cut the part.
