Re: [CAD_CAM_EDM_DRO] EDM spark control system

Hi all:

Me too, me too!!!

I just bought a little Hansvedt sinker and I want to convert it to CNC
(or maybe build an orbiter for it)

I am more than willing to look inside the guts of my power supply for
reverse engineering tips if that is useful to anyone.

Cheers

Marcus
