The part I was wondering about is whether you plan to expand the 3D toolpath strategies further. Right now the 3D raster retracts to safe Z between scanlines and enters the material with a vertical plunge. Do you think it would be technically viable to add things such as:

• ramp or helical entry instead of a straight plunge;
• continuous bidirectional/zig-zag finishing, staying on the surface whenever it is safe instead of retracting every line;
• offset/contour or spiral-style 3D finishing strategies;
• smarter linking between 3D passes, similar to what you just implemented for the optimized 2D paths.

I moved the reply to this topic as i did not want to hijack the original posters topic.

Thanks for the thorough testing and for sharing WoodCam’s code. It was a real help.

Based on your suggestions, the 3D Profile now has:

• a raster finish that stays down between lines whenever that’s faster than lifting, with smarter links between passes;
• a new Waterline (contour) finish with ramped step-downs, which also clears flat areas;
• a machining boundary, cleared down to the model’s base, and an option to sink the model below the stock top;
• end-mill roughing, after which the ball finish skips flat areas the end mill already finished.

It all still works directly from the mesh, with no CAD solid. I have added an acknowledgment and pointer to your WoodCam project on my git page. Any other suggestions are always welcome.

Thanks again!
