/S4_Filament_motion_sensor

A Filament motion sensor originated from VORON M4 Extruder

S4_Filament_motion_sensor 中文说明

Objectives

This project originated from# VORON M4 Extruder，Thank Voron team to facilitate these great project.

The objectives for this project are:

  • When the filament is exhausted or plugged, pause printing to avoid failed printing.
  • Easy to manual feeding when refueling.

Pin

Config

[filament_motion_sensor]

Filament Motion Sensor. Support for filament insert and runout detection using an encoder that toggles the output pin during filament movement through the sensor.

See the command reference for more information.

Copy below config to your <Printer.cfg>，you must need to check the “switch_pin:”

[filament_motion_sensor S4]
detection_length: 7.0
#   The minimum length of filament pulled through the sensor to trigger
#   a state change on the switch_pin
#   Default is 7 mm.
extruder: extruder
#   The name of the extruder section this sensor is associated with.
#   This parameter must be provided.
switch_pin:
#   The pin on which the switch is connected. This parameter must be
#   provided.
pause_on_runout: True
#   When set to True, a PAUSE will execute immediately after a runout
#   is detected. Note that if pause_on_runout is False and the
#   runout_gcode is omitted then runout detection is disabled. Default
#   is True.
#runout_gcode:
    #RESPOND TYPE=error MSG="Filament Runout!"   #respond a warning message 
##   Need enable the "M118" and "RESPOND" extended commands first. 
##   More infomation ：https://www.klipper3d.org/G-Codes.html?h=respond#respond
    #Bee_Mario_B                                 #Make a warning tone
    #M117 Filament Runout!                       #Sent a message to LCD
#   A list of G-Code commands to execute after a filament 
# runout is detected. If pause_on_runout is set to True this G-Code 
# will run after the PAUSE is complete. The default is not to 
# run any G-Code commands.
#insert_gcode:
#   A list of G-Code commands to execute after a filament insert is detected.
# The default is not to run any G-Code commands,  
# which disables insert detection.
#event_delay: 3.0
#   The minimum amount of time in seconds to delay between events.
#   Events triggered during this time period will be silently
#   ignored. The default is 3 seconds.
pause_delay: 0.5
#   The amount of time to delay, in seconds, between the pause command
#   dispatch and execution of the runout_gcode. It may be useful to
#   increase this delay if OctoPrint exhibits strange pause behavior.
#   Default is 0.5 seconds.

Below config is optional, unless you want make a tone when detected a runout.

  1. Copy <Beeper.cfg> to the config folder

open <Beeper.cfg> check the pin: of [output_pin BEEPER_pin]

  1. Copy below config to your <Printer.cfg>
[include Beeper.cfg]
  1. Uncomment the runout_gcode: of **[filament_motion_sensor S4]**in <Printer.cfg>
