To be fair i said Mach3 for simplicity, cos the documentation for linux cnc aint great.. i suppose it would be if it were updated as much as the software.. but the chap maybe good at Linux I personaly think its crap IMHO LOL (oh 30 years as software engineer lets me say that) LOL i know Jonathan likes it as well. but when the hardware side of things is sorted he will have a better idea of where he is and then who knows LinuxCNC could be the way for him..
