Hi Curt,

Thanks for taking the time to figure out what we need and are looking
for. As other have mentioned, the CNC mechanicals and such are pretty
easily done and well documented all over the place. If it looks like
fun for you to do, go for it, after all you should have some fun with
this too!


I am really interested in the EDM specifics. Power supply, current
regulation, voltage requirements, flushing, filtering of the water,
type of water required, Electrode material, etc.

Most commercial EDMs that I am familiar with have CNC controls
designed specifically for EDM. They are also adaptive controls
wherein they automaticaly adjust the "Feed rate" during the actual
cutting process. I think this could be a bit of a problem with some
of the current software for CNC available to hobbiests, but, as with
all things, creativity can overcome this.
