Re: Software Question

---First of all thanks for the help. I was told to go Dos by some
others but after checking here will stay Win.
Tom thanks also as I want to be able to drive steppers on the
axis. The electrode is being setup as a one shot with a 555 and a
comparater. With all this time and to keep active in some ways I was
thinking of also making it multi-purpose. I mounted a small mill
table on a drill press. You know the type that you have hard time
finding.(cast about 300lbs.)It would make a small mill as I can
change the head easily.
Thanks John
