I've been working on a CNC machine from scratch which I've been keeping a complete video log of the whole build. It's my third month on the machine and I have about 31 videos so far from the complete structure to the the electronics. I have just finished the power supply, driver and hooked up the motors and I tested the machine with perfect results. If you're interested in building one to help out your mods, this may be the ticket. If you're wondering what a CNC machine is, it's a computer controlled cutter (router, dremel, extruder, etc.) that run on 3 axes. Here is the link: www.BuildYourCNC.com I would love to hear some constructive criticism on the build, in this thread.
