Announcements like this make me glad I started my first machine conversion using Linuxcnc. The only reasons I went that direction is because Mach couldn't support the hardware on that machine, and since it's free why not at least give it a try.
Contrary to popular believe learning Linuxcnc isn't that hard, and Linux has won over this long time Windows fan, or is it more that MS blew it and has pushed me away.
