ENDER 3 V2 Card V4.2.2 Filament runout wiring
I try to use the Filament Runout on my ENDER 3 V2 (Card version 4.2.2) and I have an issue. I think it comes from the wiring of the sensor.
Could someone confirm that it's as shown on the picture because I have some doubts.
Yes, you also need to update the firmware and enable the filament runout , I installed marlin 2.0.7 and enabled the bl-touch as well.
The material break detection line is connected like this, the mainboard firmware needs to be refreshed to use the material break detection function
Ender-3 V2-Marlin-2.0.1 - V1.2.1 - Filament.bin
Yes, there is an error in the drawing, the red and white wires are reversed, if you look on the back of the card there is the correct writing. I also had the same problem as you, luckily no damage, reversed the wires and it worked right away.
