Up to this point, I’ve been able to mechanically assemble my ZTW CNC router, wire it electrically and find a shelving system to store it. I also came up with a way to mount my Dremel tool to it and move the axes manually using Mach3. So far, so good, but the real beauty of a CNC machine isn’t manually jogging it, it’s programming a code and letting it cut things for you. Here’s a couple of my first cuts using automatic computer control. I’ll explain how it’s done after the break.
