The Budget CNC Model 4M delivers the freedom of multi‑purpose CNC machining at a price that finally makes sense for everyone. The Model 4M is a full-sized 3ft by 2ft machine designed from the ground up for makers, hobbyists, educators, and small shops, combining open‑source flexibility, hardware‑store maintainability, and surprisingly capable performance in a compact and mechanized gantry‑style frame.

Everywhere possible, the Model 4M is built from everyday components like those you can find at your local hardware store. That means repairs are simple, upgrades are affordable, and long‑term ownership stays firmly in your own control. There are no proprietary parts or inflated replacement costs, which allow you to keep building at every turn instead of waiting or needing to find alternatives.

As part of the Budget CNC open‑source family, the Model 4M gives you complete freedom in how you acquire, assemble, and customize your machine. Whether you want to fabricate your own panels, order a ready‑to‑assemble kit, or receive a fully built machine delivered locally, you can choose the path that fits your tools, skills, and budget.
