* I used Kicad to produce the Gerbers and then used [http://circuitpeople.com/] to create a 600 DPI PNG file. I'm not sure if more recent versions of Kicad produce usable print files or not. | * I used Kicad to produce the Gerbers and then used [http://circuitpeople.com/] to create a 600 DPI PNG file.

* I would be inclined to increase the width of both signal and power traces. Also, for SMD ICs I would increase the length of the non-connected pads to make soldering them by hand easier. | |||
* I used GIMP to lay-up multiple copies of the board to be etched in one file. On the CAD station it's in German language but the pretty icons help. | * I used GIMP to lay-up multiple copies of the board to be etched in one file.

* Don't use the mill bits from the drawers under the CNC/RepRap machine. Try looking in the very thin drawer at the top left of the tool drawers for drill bits. Try 0.8mm size. Drill carefully. Be prepared to buy more. :-) | * Don't use the mill bits from the drawers under the CNC/RepRap machine. Try looking in the very thin drawer at the top left of the tool drawers for drill bits.
