Homebrew PCBs

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.
