Homebrew PCBs

Ahhh. I had already seen the T-Tech one so I wasn't searching on it
again.

I'm not actually interested in buying it, but I amd collecting pictures
of CNC PCB machines, hopefully to give me ideas for the day that I build
one.

I think that the irregularity in the round pad is due to incorrect
backlash compensation or something similar. Circles seem to make this
really show up.

Thanks
