+I tested two random filament runout sensors that I had on hand. Both work just fine. It seems to me that any sensor with `VCC`, `Ground`, and `Signal` pins should work.
 
-## Lead Screws and Rods
+In order to get the filament sensor working, just make sure that the `VCC`, `Ground`, and `Signal` line up with the pins on the hotend PCB, port `P7`.
