Make Your Own PCBs on an Inexpensive Desktop CNC Mill
After you've engraved your circuit you need to cut it out from the copper clad stock somehow. So far I've done this by scoring and snapping the copper clad, cutting out the board with a 40tpi blade in a jigsaw, using a paper cutter and using hand written G-Code for the CNC to mill out the board.
