I am working araund the schematics of radds. There are a capacitor (10nF) from signal and gnd. I have a pullup ( into the processor #define actived) that should keep the tension high. Ok ; my endstop

Ok, but i have #define endstop_pullup_(all)_min ( and Max) set to true, i have #define endstop_(all)_(min and max)_inverting false and #define (min and max)_hardware_endstop_(all) true.
