Re: [CAD_CAM_EDM_DRO] A little bit of help; Always works!!!

Anthony:

On my web page there is an FAQ which shows a typical schematic to hookup
your machine electronics. Almost any software you decide on will hookup in
the same way and this schematic is a good overview of the electronic side of
hooking up a small (or large) system. The wiring won't even vary much from
program to program or hardware to hardware design. The schematic shows
pretty clearly how little there is to getting a system workin in terms of
the electronics and wiring.
Good luck with the retrofit.
