:)I have been away from Mach3 long enough to forget everything I thought I knew. I may humbly ask for your help and guidance. I started using Mach in 1997 so I'm much older and slower so please bear with that. I am working on converting my Plasmacam plasma cutter to Mach 3. Yes I have already hear go to Mach 4. My plan is to get it going with Mach 3 and when I feel smarter I will move on to Mach 4.
