I guess it is a good project in control circuitry but how in the world could you actually machine something useful with that thing?

On a similar topic, has anyone seen the little Roland tabletop CNC mills. The computer thinks of it as a printer. And the software they come with, you don't even have to write a computer program. You basically just import your model as an STL, press "go," go get lunch, and come back to a cool little part. They are fun little toys but they are so small, weak, and slow too that I can't justify the $3500 price. I was able to make a nice #25 sprocket with dog pockets in it though (out of PVC). It took about 4.5 hours! Anyway, very easy and fun to use, but not incredibly capable.
