Ok Daniel....which one did you make?
The Bic, the quarter or the stolen boiler plate off an alien space craft held at The Skunk Works?

Its a board to hold a programmable chip and interface 4 potentiometers, a switch and a high power RGB LED. Its for color mixing and phaseing, possibly for a liquor shelf or something.....

Did you use Eagle to design the PCB layout/cut file? I've looked at that package for use in a couple of projects, but always got sidetracked before I got around to trying it out.

What size bit did you use to cut away the copper cladding? Did you drill the holes with the same bit?
I cut some FR4 with my shopbot and it eats bits. What is your board material?

Yes I did use Eagle,
Dana, I used a large pointed round over bit to cut the traces, It's the only bit I have thats even close to being able to do the job. I need to experiment with some other bits, I don't know what the board is.......It's the first time I've ever done this and I got the board out of a stack at a surplus store. The bit for the holes is .025in.

Check out www.precisebits.com (http://www.precisebits.com)
They have specialty bits specificly for doing circuit boards.
most of them require an 1/8" collet though. (which they also sell for The PC router)

Daniel, what feed rate did you use for that board? I've tried this using one of Precise Bits V cutters and ended up ruining the bit. I used PCBGCode within Eagle to generate the tool path.
Great job on the board!

I cut the traces at 1.7 in/sec with a large pointed roundover bit. The holes though required a very small bit. I set the plunge to .05 in/sec on those.
