I have really enjoyed getting into building CNC routers. They have provided a lot of new capabilities for us in our various project builds by allowing us to custom make parts out of wood and metal that would be practically impossible to make any other way. I have built two CNC routers now, the first a largish table-top design based loosely around the ‘OX’ design put out by Mark Carew and OpenBuilds.
Bigger & Stronger
The second is a full-size 1500x1000mm machine of my own design. The first machine was a lot of fun to build but it had some limitations with respect to materials it could work with. I built the second one to get a bigger cutting envelope and the ability to work with a wider variety of materials.
