CNC Router

Published January 22, 2018

Wanting to increase my ability to prototype projects at home, and learn more about Computer Aided Design (CAD), Computer Aided Machining (CAM), and machine design, I undertook to design and build a tabletop Computer Numerical Control (CNC) Router. After several weeks of research on small-scale CNC design, motor control, linear guides, and some initial budgeting, I began mocking up a machine in SolidWorks that could be built using readily available materials and wood shop tools. Using ball bearings from roller blades, linear guides from a photographic enlarger, and many hardware store parts, I achieved what I believe to be very good balances between precision and size, build quality and budget, along with a high degree of “upgradability.”
