Homebrew PCBs

Cristian,

Horizontal would not work using the cnc axis as a wire feed (as far as 
I can see anyway), since the wire is consumed in the erosion process, 
the roller feed also automatically compensates for the loss of 
electrode. Also, how would you submerge the electrode and workpiece in 
the dielectric?

Your offer of electronics design could be helpful. I will dig out my 
work and review it.
