FWIW, I tried very hard to find every possible CAD/CAM program when researching the Shapeoko wiki.... though I found Cenon because I was a long-time NeXT user.
That is why I settled on it. The other one I was working with was FabBSD. I still have the source to that it is an OpenBSD focused on CAM. I think the developer lost interest when OpenBSD switched the security model for GPIO.
