Yes, all my limits switches are working. I have them in series.When I go to diagnostics screen, and trip one of the switches, all three lights go on as expected. I have them set up for 5 volts. Everything seems hooked up correctly, but when I run an axis to the switch, it will not stop. I get no EStop. I have tried active high, active low, to no avail. Like I said, The manual limit override is constantly flashing. Is there a way to reset or turn this off?
