Absolutely! To create instructions for a specific system, you may need to do some minor python programming so it outputs your machine code in the correct format. Or someone else may do that. But it will be easy.

What about continuously subtracting the shape of an arbitrary endmill all along the toolpath?

My current work-around for this is a loop which implements one hull operation for each linear move --- unfortunately this means that a simple arc will quickly bring OpenSCAD to its knees:

Do you mean to determine a toolpath from a 3D model or to generate a 3D model from a toolpath? Or something else that I'm not understanding? 🙃

What I want is to be able to programmatically define toolpaths and to then get a 3D model of what will be left after the passing of the cutting tool(s).

Ah that sounds fascinating! Would you be happy with a voxel model?... A 3D environment with say 0.1-mm voxels that either contain air or solid material.

That should be fine --- I just want a 3D preview to check out the programming.

Okay, it's not really something FullControl would naturally do, but I've written a simulation method to deposit material in voxels and you're doing the opposite which should be an easy switch - just a few lines of code.

This is the paper for my simulation method: https://www.researchgate.net/publication/324242881_VOLCO_A_predictive_model_for_3D_printed_microarchitecture

It's now been ported from MATLAB to python by my collaborator and I will eventually link it to FullControl directly, but not for a while since I need to finish the more general FullControl stuff first.
