Re: Langlois EDM

I have to second the other opinion against using Langlois' plans for
any commercial of professional level burning. I built the unit from
the plans as they progressed through HSM years ago. I was
disappointed with Part VI, since that would have been the most
important part of the electronics.

Good luck with your build however. It's pretty enjoyable. You
should check out the other EDM plans on Dan Mauch's site too.
