Wow!
Did you look at the recent issues of Nuts and Volts magazine? There is a 4
part article in there by Dan Mauch on making an NC controller and converting
a small drill press to NC control. I bought the July issue, and I am
ordering the other issues.
I have a lot of questions for you regarding Unix - I was wondering if I
could see your setup. Could we get together and swap info?
Tom
p.s. - yes of course we can trade mill time for hot wire time
