RapidCAM.app is still taking up all my time. It is a 2.5D, parametric CAD/CAM program for CNC and laser with flat or 4th axis. Open source, free, run completely in browser.

This is a passion project that I want for my own use but am happy if other's find it useful and very open to feedback and collaboration.

The file system is open and very well defined so that AI can write files. There is an AI Assistant dialog that helps you to write prompts and then takes the AI file and runs the file through a solver and checks.
