In principle, CNC isn't limited to routing ... t have a handy way to adapt an air filter to the machine and the laser project seemed fairly simple, I focused my attention on the milling functionality.

Hooking up a laser to a CNC gantry isn’t exactly an Earth-shattering innovation, but it does make for a useful tool. Even a cheap diode laser mounted to an old 3D printer can do engraving ...

Originally (as the name implies) it was geared towards laser cutting, but the project has since evolved to support CNC routers, vinyl cutters, and pretty much anything else that can follow a DXF file.
