I’m with @chop on this one. I’m not going to use this for profit, just a fun thing to mess around with and show the kids at my significant other’s work.
Mach 3 is what we use for our production table. It is already being used in almost every single CNC fabrication method so it has all of the kinks worked out. Plasma, 3+ axis milling, I’ve even seen flame cutting and automated welding. But like you said, @vicious1, it does cost money. In the long run for a production unit, it’s a no brainer. At the hobby level, it’s sometimes hard to justify.
