Filament Runout sensor Housing for Ender z-limit switch and bearing
Description
I made this housing for those who want to use the z limit switch laying around as a filament runout sensor after installing BL touch. I designed this housing to use with a couple of skate board bearings so it doesn’t grind the filament when it goes through. Also it’s a bi-dirctional so it shouldn’t affect your retractions. The mount supports M3 screws, 4mm v-slot screws and zip ties so you can mount it on the z rod fixture or on the top of the frame if you use direct drive. With the wiring of the switch, I only used two wires. One from “s” on sensor side to the left end pin on the runout sensor port on board. Then from “v” to the second pin on the port. Then enabled filament sensor on Jyer firmware. Cheers.
