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.
