i unchecked the spindle relay disable. now i get a flashing normal adnormal light. the message says, [list of adnormalities,  axis are not refed to normal condition.]  i am using screen program run alt-1. when i run the code now at the m3 it still pauses but does not turn the spindle on. when i ref all home they all do there normal thing  &all read 0.000. on my screen, the spindle speed is on the lower right corner. when i click on the togglecw f5 it still does not start. when the spindle disable was checked it sometimes started from the m3. any ideas about the flashing light? if i take a digital meter & put it on the pin for the spindle should i get a reading of some kind when i click on  the spindle cw f5 box? thanks greg
