@dteel said in How to use duex5 end stops with RepRap3 firmware:
Not that I can tell, there was no noticeable difference other than it homes correctly now. I just had to add the ^.
The endstops on the DueX have LEDs close to the endstop connectors. The LED and its resistor act as the pullup, so it should not be necessary to enable the internal pullup resistor. However, if the LED is missing or open circuit, then it certainly would be necessary to enable the internal pullup resistor to make it work.
