Its what many people have been wanting for a long time. It now means Mach is a machine controller and not just a CNC controller.
My mind is buzzing with uses for it.
In theory you could design a machine that makes pizzas, from the dough, to all the toppings, the cooking, cutting, etc. All controlled by Mach on one computer.
Personally I think this is the biggest addition to Mach in years. First Art won a big piece of the CNC market, and gave CNC to the masses, now he has also given total machine control to the masses too.
