Thanks all...turns out the dir pin on my bob is permanently high. However, l am getting some weird behavior in other ways,too. I am afraid the noise is getting me . Just for reference, what should the min dcV be on a pin to be sure the voltage is high enough to be safely recognised? Also, l'm new at this so forgive the stupidity, here, but how likely is noise interfearance if your not using shielded cable? One more thing, does anyone have a cable part number for something that will work with a 42vdc supply, 6amps, and 8 ft wire runs?
Thanks in advance.
