Here is a homemade cnc router I built. I always wanted to make one but had no idea how to go about it. I came across cnczone.com and and within a few weeks of lurking I was on my way to making my own. It’s made mostly of MDF. The controller is a kit that I bought from hobbycnc. They provide the parts for the controller and you have to solder it all together. The power supply is 36v which is more than enough to push the three stepper motors. It’s remarkable how accurate this can be. I often carve something out with a “V” bit, reset the bit to where I started, lower it just a bit, and then re-cut to clean it up. It follows the same path as the first.
Thanks for looking!
