K8400 filament sensor


Hello, there are still some free entries on the board, it is possible to integrate a filament sensor. according to firmware, he is indeed supported, unfortunately, you will not find a post on which pin you should put the sensor. can someone help me?


I do not own a K8400 but the Vertex Delta K8800 has a Filament sensor. Maybe you want to have a look in K8800’s schematics for inspiration:
