So with that being said we should purchase the license version correct?
Imo, no one should even be considering Mach3 for a new machine. It's basically 10 year old, unsupported software.
Either pay a little more, and go with Mach4.
Or go with one of the competition, many of which are arguably better, and cost as little as 1/3 the price.
Either option, though, will require a new control card which would be an additional $125-$200.
