TriangleLab Filament Runout Sensor Detector for 3D Printer 1.75mm Filament

Description

Product Features
Kit includes:
1pc Runout Sensor
1pc 3pin Cable
3pc Cable Connectors
2pcs Screws w/ nuts
1pc PTFE Tube
Product Description
This filament runout sensor is designed for detect whether your filament is run out during the
printing
process.  The sensor will send the signal to the printer when the filament is run out and printer will pause the print job until the new filament is loaded when the printer w/ correct firmware and setting.
Supply Voltage: 3.5-5V
Filament : 1.75mm
Size: 37mm x 44mm x 10.6mm
Installation:
Please install the unit after the spool and before your extruder.
Fix it on your printer and along with the path of filament is recommend.
Pay attention to the direction indicated by the arrow on the body.
Inserted the 4mm PTFE tube to both side of the unit for guiding the filament and help to reduce the friction.
Wiring:
Locate the Primary Cable (see pictures for identification) and connect to the Filament Run-Out Sensor connector.
The wiring has the following identification:
Red Wire   - 3.3-VDC to 5-VDC (supply power)
Yel/Blue     - Signal Wire
Black Wire - Ground
Connections:
Servo pins always have the right connections: Power, Signal and Ground.
Most End-Stop pins will have the same 3 pins, and sometimes only Signal and Ground. If you only have these two in an end-stop connector there should be somewhere on the main board for Supply Voltage.
In theory you can chose any input pins on your main board for signal.
Expansion:
If you have a multi-head 3D printer then you would want to have a filament sensor for each extruder being fed filament.  It is a very simple matter to connect the sensors in a daisy-chain fashion and a jumper cable is supplied with each kit to allow connecting the sensor in a daisy-chain fashion (see pictures).  The sensors are connected in parallel so any one out of filament will signal the main board to pause until the filament is loaded by the operator and printing is resumed.
Firmware configuration:
Marlin:
Make sure your firmware has the filament run-out feature, you need Marlin 1.1.0-RC7 or newer. If you are using an older version, contact your 3D printer manufacturer or update your firmware configuration manually.
IN the Configuration.h file make the following changes:
#define FILAMENT_RUNOUT_SENSOR
In the Configuration_adv.h file make the following change:
#define FILAMENT_CHANGE_FEATURE
In the Pins_[BOARD NAME].h file make the following changes (BOARD NAME) is the name of your main board
#define FIL_RUNOUT_PIN [DIGITAL PIN INPUT]
Note: DIGITAL PIN INPUT is the input pin being used on your main board for the Signal input.  See you main board documentation to determine the pin being used.
Repetier:
Make sure your firmware has the filament runout feature, you need Repetier 0.92.9 or newer. If you are using an older version, contact your 3D printer manufacturer or update your firmware configuration manually.
Configuration.h
#define EXT0_JAM_PIN [DIGITAL PIN INPUT]
#define JAM_METHOD 3
#define JAM_ACTION 1

Pause when out of filament
This configuration allows you to use a pin to detect when the machine is out of filament. When the switch is hit by the filament not being present, the machine is put into pause.
Another switch is configured to allow you to resume the machine once the button is pressed.
Additional configuration allows you to specify commands that are executed when the machine suspends, and when it resumes.
switch.filamentout.enable                    true          # Enable this module
