Ender 3 v2 filament run out switch box

thingiverse

Im running jyers ui to enable filament run out sensor in my ender 3 v2. This wont work with previous enders unless youve updated mother board to v4.4.2 or v4.4.7 as these newer boards have port to plug switch into. Great video on jyers firmware (not me).A cool feature of jyers firmware is it makes bed leveling super simple, no need to disable steppers anymore, just click where you want it to go! https://www.youtube.com/watch?v=o1zXYwgIPLY Heres great video(not me) to set it up https://www.youtube.com/watch?v=2l7c3A6_eT4 Link to micro switch https://www.amazon.com/InduSKY-Switch-Momentary-Roller-Switches/dp/B08736NP44/ref=asc_df_B08736NP44/?tag=hyprod-20&linkCode=df0&hvadid=475843397258&hvpos=&hvnetw=g&hvrand=18357164394454335009&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9017180&hvtargid=pla-974750520630&psc=1 If you dont have the 3 pin connector to plug into mother board you can use a 4 pin and just trim off side of it which is what I did,since 2 pins are next to each other you could probably use a 2 pin connector and sand one of the arrow like protrusions off face so it will plug in. Dont forget to save your changes on screen after checking the filament run out box on jyers firmware. The filament guide wheel rotates on a servo motor screw but anything 3mm should work.
