Klipper Configuration

Filament Runout Function Configuration

⚠️ The filament diameter in the configuration file must be changed to 2.85mm
and also changed to 2.85mm in the printer configuration profile of the slicer.

[filament_switch_sensor mdm_switch_sensor]
switch_pin: ^PG12 # Replace with the pin being used, connected to the runout detection pin
pause_on_runout: True
# When set to "True", the printer will pause immediately after detecting exhaustion.
# Note that if pause_on_runout is False and no runout_gcode is defined,
# the runout detection will be disabled.
# Default is True.

runout_gcode:
    PAUSE
    M118 Filament Out
# insert_gcode:
event_delay: 1.0
# Minimum time delay (in seconds) between events.
# Events triggered within this timeframe will be ignored by default.
# Default is 3 seconds.

pause_delay: 0.5
# Delay time (in seconds) between the pause command and executing runout_gcode.
# If using OctoPrint, increasing this delay may improve the reliability of the pause.
# If OctoPrint exhibits strange pause behavior, consider increasing this delay.
# Default is 0.5 seconds.

Filament Jam Function Configuration

[filament_motion_sensor mdm_motion_sensor]
switch_pin: PD6       # Replace with the pin being used, connected to the jam detection pin
detection_length: 3.7 # Minimum distance for triggering a change in the state of the switch_pin
extruder: extruder
# The extruder associated with this sensor.
# This parameter must be provided.
    
# pause_on_runout:

    PAUSE
    M118 Jammed
# insert_gcode:
