I was wondering if either Curt or Roger
would be willing to shre their circuits
with others. Some of us are a little
bit lazy and have a little to much other
stuff to design. An RTFM build would
be greatly appreciated. Even if it was
less than optimal.
I also don't know how fast the EDM PCB
could run. But I did a quick (stupid)
test with my fronius magicwave 180 amp
tig welder. I couldn't get 6 thou trck
spacing - but MY was the copper removal
rate fast :D:D:D
