Both fun and educational to build your own CNC Router

Building your own 3-Axis CNC router is both fun and educational. This Instructable shows all the steps I followed to make my DIY CNC Router. This is the second one I made, after learning a lot from building the first version.

This is a very good router that can be built at a reasonable price using readily available available materials. This design uses DIY linear bearings, threaded rod and plywood (or MDF) construction. No welding, no fancy materials.

This is not a mill designed to machine steel. It is not super-fast. It is a router designed to route wood, plastic and some aluminum. It is a low-cost, decent quality system that will teach you all you need to know about 3-axis routing.

If you take care during cutting and assembly, you can achieve very good accuracy. I also use mine to do printed circuit board isolation routing, and I can do surface-mount ICs with 50mil pitch. Not bad at all!
