RapidCAM.app (https://rapidcam.app) has excellent support for AI. The file format specs are published and open source so AI can easily write an ".rcam" file.

RapidCAM.app is a parametric 2.5D CAD/CAM for CNC and laser with support for rotary axis. RapidCAM.app runs in the browser or as desktop apps. There is no login required. The app is free to use. Privacy is respected. rcamhub.com is the sharing site for .rcam files.

Within the App, you can define your project and then use the built in prompt generator. This creates a prompt with all the details AI could need. Once the AI replies with the file, you can paste it back into the app which will then verify the file for you.

Desktop versions of the app have MCP server built in so AI can control the app directly if that is a route you prefer.

I started RapidCAM for my own use as I found that the CNC was sitting idle simply because firing up a full CAD/CAM package took too long. The idea with RapidCAM is that you can quickly sketch out your job from as simple as you need to as advanced as you want going from unconstrained to full parametric/constrained as required.
