Well it's not entirely stock, I use a princess auto brand (power fist) 'dremel' that runs at 1.2A where as the stock 'dremel' that comes in the kit runs 1A, the PF brand had a better body for the stock clamps. However as you can see the board works well enough that the AVR mk2 programmer gets a green light.

10 ipm XY
4 ipm Z
0.003" depth
0.0157 kyocera end mill from drillman1 on ebay.

Board designed using eagle and g-code from pcb-gcode ULP

I had to do some quick sanding since some little burrs of copper were left on some of the edges (Maybe need to play around with the speeds to get this not to happen, any insight some more seasoned PCB millers could provide would be much appreciated). Just had to probe around for shorts (only 1 on the board and it was a burr that fell down into the valley, quickly removed with the point of an exacto blade) but otherwise went great.

So there you go, 'stock' SO2 making a working PCB.

Excellent.
