Ron the Mach2 manual is in the process of being completely redone. It is a large pdf file ( well it is for me, dialup)
so I am going to offer another option. Mach2 has a yahoo board that has tons of folks that can help you. I was really hoping they would move here to the zone and after Paul gets the new upgrade done who knows? You can find the link on the mach2 site .
