E2 and E3 stepper filament sensor

  • Hello,
    I am using Duet 1.03 and Duex2 board on my idex printer. Right now I am using E2 and E3 stepper drivers for the extruder. When i try to configure filament runnig out sensor using endstop switch it is not working. I connected to output E2 endstop and E3 endstop. How can i configure them ?

    here is my config.g

    From https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M591_Configure_filament_sensing:

    Cnn Which input the filament sensor is connected to. On Duet electronics: 0=X endstop input, 1=Y endstop input, 2=Z endstop input, 3=E0 endstop input etc. If you have a Duex 2 or Duex 5 in your system, note that C5 thru C9 (the endstop inputs on the DueX) cannot be used for filament monitors, but C10 and C11 (the endstop inputs on the CONN_LCD connector) can.
