CNC (computer numerical control) machines can be used to make virtually anything you can imagine out of a variety of materials such as wood and metal. They’re great for inventors, artists, and hobbyists to create perfect shapes and curves, as well as create objects that no one has made before. But why buy a premade CNC machine when you can build one yourself? That’s exactly what Bill has done. He designed all of the plastic parts using Sketchup, Inventor Fusion, and Fusion 360, and then 3D printed the parts on a Prusa i3. He sourced other parts on eBay, Amazon, and Openbuildpartstore.com, and powers it with Arduino, Grbl, and Universal G-Code Sender.
You can do this too! Stop by Bill’s table at the Maker Faire and he will be happy to explain how to get started.
