Mach3 vs Mach4

[Swarfing]

Sour grapes to those that poo poo linux because they do not understand what they are doing without the crutch of microsft. Always used Emc2 (linuxcnc) and since setting it up never had a problem. At least the linux fraternity will never shove it's problem under the carpet. Once you get it set up it works great, the forum will get you through most problems you may have (not many as they have all been seen before). PC is biggest hurdle, but if you look on their site they list a good few that work but what i find is the simpler the machine and you switch all the on board stuff off that is not needed you are fine. Check out mother boards that boast high back bus speeds rather that processor speeds. a good chunk of ram, separate graphics cards with good ramdac and you are on your way.
