WebFeb 24, 2013 · Depends on the type of endstop. Some work this way, some inverted. Optical endstops never need pullup resistors. You can turn them off, they just waste current. Testing an endstop is as simple as measuring the signal on the signal pin with a voltage meter. It should swap between 0V and 5V when the barrier is interrupted or not. WebJul 23, 2013 · I suspect that this is there so that if you're using a mix of different endstops or only using some of the endstops, you can define which ones are pulled up and which aren't, and simply #defining ENDSTOPPULLUPS puts pullups on all of them.
