I am only just beginning to get into the cnc scene. But, from what I gather about Mach 3 is that it is very feature rich for the price but it is picky. And, with me just getting into the hobby, Id like to stick to tried and true methods. Its only a cnc plasma table. I dont need top notch, nor all the bells and whistles. But, then again this is my first machine. Do you have a good resource for this ethernet smooth stepper topic, where I could read up on it? After all the trouble I just went through with Windows XP and the first parallel card Its sounds like a definate possibility in the future.
