Working in 2D: Using a CNC Mill

Posted by Erica on Oct 10, 2013 in Making, Woodworking

I have been enjoying the 3D printer. It’s very easy to go on Thingiverse and download toys and objects to print. My ultimate goal, though, is to design my own parts for the machines I want to build. And that means learning computer-aided design (CAD) software. There are quite a few of these around for […]
