Sorry, support was the wrong word.
Updates and bug fixs. Thanks for the direct responce, ger21.
Looked at LinuxCNC a few years ago when i was day dreaming about machines, i run linux (ubuntu) on a headless server at home for close to ten years (think ver 10 was last update) and there desktop along with played around with different linux "flavors" so i have alittle exposore to linux. Mach seams (through reading) more stable and user base supported. Will give LinunxCNC a shot, but as it looks now, Mach will be my choice.
