I very recently completed rebuilding the y and z axis of my homebuilt CNC router. However even as I was finishing that build, I knew the z-axis design was no good.
I've been quite busy over the summer, and with the lovely weather I've been less inclined to spend any time locked away in my workshop with no windows. However, I have been designing and thinking about my CNC.
For some time I've toyed with the idea of building my own cnc router, or perhaps a 3d printer. The idea, of having a tool which allows me to fabricate parts using a computer to control the process, is pretty compelling.
