If it falsely reports "triggered" every time, then it won't work. It sounds like one of your wires (either GND or VDD) has a bad connection (not completely sure, but that's what I'd suspect given the symptoms). You could also have a short (likely to ground).
Nope, it's not a short, it reports triggered when I trigger it, and the voltages on the wire, connector, and solder point all show up fine. I sort of figured out what's happening: the LED doesn't come on, but it still reports triggered when I trigger it. I looked closer, and just out of sheer coincidence, the wheel wasn't triggering the switch anymore, as if the switch was too far away from the v-wheel to be triggered. I put an extra washer in to raise it and voila, it works, but the LED still doesn't light up. I thinking I'm gonna chock it up to the led burning out coincidentally at the same time as the switch stopped triggering.
On to the next problem: the z-max WAS lighting up, but not showing "triggered". While testing the other endstop, I decided to swap the z-max with the y-min, it also didn't light up when plugged into the same plug. So I swapped them back, and now the z-max doesn't light up or show triggered (it didn't show triggered before, but at least it lot up). The evidence seems to imply that particular plug is burning out LEDs, but I don't see how it could be. The voltages all tested at ~4.8v, it's very odd. Unless these things are just very fragile and/or cheaply built.
I was wondering if someone could report their pins.h configuration to me that has the Azteeg x3 (or even RAMPS, because it's apparently the same pin assignment). I want to see if my z-max pin is set properly, because it looks like it's not because it WAS lighting up but not showing as triggered.
