I have started a new project for gcode generation out of Moi3D. Right now I can export simple paths that work on my Haas machining centers. Every CAM software I have ever used spits out dirty gcode. My goal is to create a plug-in that exports clean simple code that makes use of the machines advanced g-code functions, for example exporting G2 and G3 arcs instead of a bunch of tiny line segments, letting the machine manage tool diameters, and using the built-in pocketing operations.

Let me know if anyone is interested in contributing.
