Re: [CAD_CAM_EDM_DRO] Machine Setup

Thanks Les, The G100 is in the cards for sure, I'm kinda holding out to see how this machine run's first before either jumping to servo's or..?? [not sure.. might wait for the unstallable stepper thing if this current design is good enough power wise] Is it possible to somehow shield the parrallel cable? I was wondering if wrapping it in that aluminized tape would do it or.. I can get my hands on actual copper foil [ used in making electrical cable] which I could wrap around the cable and then ground with the rest of my shielded cables? Is this a no-no or..?? I'd really hate to have to get that long of a mouse, VGA, and keyboard cable if I can help it :-) It'd be much easier to just run two [ power and parrallel].. I've already know that the easy route isn't always the best so.. I'll take the best route, but.. you know where I'm coming from..
