I currently running EMC2 on my Mill, I built a new computer for controlling the mill this weekend based on an atom board, and I thought I'd give Mach3 a try.
So I installed a copy of XP, and the Mach3 demo.
The convenience of the wizards has me considering changing over from EMC2.
Since I haven't used XP in years and my XP licenses all seem to have gotten lost/thrown out at some point I'll have to buy an OS either XP or Win7, which is the better OS for Mach?
