Hi,
if you are running a machine for a business then is Mach3 the right choice? All development ceased on Mach3 seven years ago, it still works and many people still
use it, but whatever bugs and quirks it has it will now always have.
Mach4Hobby is $200USD and is a better proposition, its more stable, has better features and a better programming language and tool suite and is still actively developed.
Mach4Industrial is $1400USD and is better again. It has parametric programming (Macro B) but more importantly you get the red carpet treatment from
New Fangled Solutions....and that's worth its weight in gold.
I'll travel to Cardiff, but I'm in New Zealand, so I'll need a packed lunch and a life jacket.
