Making PCBs this way is very slow, you know?
IME it is better to use a professional fabricator - http://www.kikipcb.com/
Unless you are making rather crude and large PCBs it's a tough job for a mill to do a good job. My PCBs have tracks only 0.2mm wide and similar spacing, that is a difficult ask for an affordable mill.

I use a combination of Eagle to do the design work and the pcb-gcode ulp to generate the necessary gcode files. For the small one off type of thing that I do as a hobbyist, this works fine.
The ulp can be found either on the Eagle site or there is a yahoo group dedicated to it.Art

It looks like those boards might easily be handled by Eagle Lite (no cost for a hobbist) and the ulp is also no cost.
Might be a winner setup for you.Art

I built my router (about 330mm x 330 mm x ~50mm) and control it with an old DOS program called Turbocnc.
The router was built with and aluminum channel and flat stock. I found some linear rails to use for the X, Y, and Z. Managed to get a spindle (only 70 watts but works for PCB work). used acme lead screws with derlin nuts for zero backlash.
Works for me.Art

How many PCB can you buy for the cost of a router?

I do it because I CAN and want to do it. Its not a money thing. I do it to prove to myself that I can. A hobby is not all about saving money, sometimes it is proving that you can do it yourself. If it was all about saving money, I would not have any hobbies and simply buy whatever it is. Also, my hobby projects are typically one off types. I have no plans to manufacture a product. So I can go from a board design to finished board ready to populate in less than an hour usually. How quick can you get a turn around on the board (one off) that you want to buy???
Its different strokes for different folks.Art
