This is how Otherplan (the milling software that is free from Othermill) renders the board. It took about 10 minutes to mill, switch bits drill and cut out this single sided PCB. I used the following bits:
- traces 1/64" end mill
- .9mm (36 mil wide drill bit) for the through holes
- V30 degree carving bit for cut out
Otherplan can read Eagle BRD files directly or you can import your own gerbers.
Blank single sided FR1 PCB mounted up and milled in the Othermill.
The traces came out just perfect and with the PCB in hand we can go ahead and solder it up.
