Mount for BTT SFS V2.0 for 2020 Extrusions. 

The tolerances are for ABS/ASA filament.

Recommended print settings:

  • 3 Perimeters/Walls
  • 5 Bottom/Top layers
  • 25% infill
  • 0.2mm layer height 

Use original screws to mount sensor to the mount.
8mm M3 Screw and M3 Hammerhead to mount to the extrusion.

My klipper configuration for the sensor:

[filament_switch_sensor switch_sensor]
switch_pin: ^PG12
pause_on_runout: True
runout_gcode:
  RESPOND MSG="Filament switch runout"
  SET_DISPLAY_TEXT MSG="Filament switch runout"              # Displays info
insert_gcode:
  RESPOND MSG="Filament switch inserted"
  SET_DISPLAY_TEXT MSG="Filament switch inserted"              # Displays info

[filament_motion_sensor encoder_sensor]
switch_pin: ^PG13
detection_length: 10 # accuracy of motion sensor 2.88mm
extruder: extruder
pause_on_runout: True
runout_gcode:
  RESPOND MSG="Filament encoder runout"
  SET_DISPLAY_TEXT MSG="Filament encoder runout"              # Displays info
insert_gcode:
  RESPOND MSG="Filament encoder inserted"
  SET_DISPLAY_TEXT MSG="Filament encoder inserted"              # Displays info

[delayed_gcode DISABLEFILAMENTSENSOR]
initial_duration: 1
gcode:
    SET_FILAMENT_SENSOR SENSOR=switch_sensor ENABLE=0 #disable filament sensor
    SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=0 #disable filament sensor

[delayed_gcode enable_filament_sensor]
initial_duration: 10
gcode:
    SET_FILAMENT_SENSOR SENSOR=switch_sensor ENABLE=1 #enable filament sensor
    SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=1 #enable filament sensor

[gcode_macro _SFS_ENABLE]
gcode:
    SET_FILAMENT_SENSOR SENSOR=switch_sensor ENABLE=1 #enable filament sensor
    SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=1 #enable filament sensor

[gcode_macro _SFS_DISABLE]
gcode:
    SET_FILAMENT_SENSOR SENSOR=switch_sensor ENABLE=0 #disable filament sensor
    SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=0 #disable filament sensor
