I finished my first diy cnc. Ordered the parts off of ebay and I'm please with the results. It's a small desktop cnc. I do plan to upgrade the spindle. I'm using a dremil right wow. I've got the itch, so now that my concept is working, I am going to make it a bit bigger and perhaps start using extruded metal.
Here are a few of my first cuts. It won't cut metal, but I have cut acrylic up to .375 inch so far.
