There is spurious noise in your limit sense inputs which is triggering the limits as far as Emc2 is concerned. I had the same problem, but I couldn't fix it through improved grounding. I think part of my problem was my logic cables which are very long (15 ft plus). I finally spotted the random noise spike on the Halscope and it was something like 5 nanoseconds in duration. I finally fixed the problem by routing the limit switch inputs through the Hal "debounce" component, which basically tells Emc3 to ignore any signal shorter than -- duration (you set the time constant). If you do a search here in this forum on "debounce filter" you should find plenty of information.
