Trianglelabs Filament Run-out Sensor

This filament run out sensor unit is design for detect whether your printing is run out of filament. During printing if the unit detected that there is out of filament it will send a signal to the main board. With correct firmware settings the printing will paused untill the operator reload the filament and resume the printing. It works with all available materials;flexible,clear,opaque,filled,etc as it physical switch. The unit can handle as many filaments simultaneously. As soon as one of them will be missing, the unit will send a message to the next one,up to your main board. Two screws are provided so you can install it where you want. Works with almost any printer. Durable injection modeling casing and industrial grade components. Technical Information: Supply Voltage 3.3-5V Operating Temperature below 80℃ Filament Diameter 1.75MM(1-2MM) Filament Presence LOW Filament Absent HIGH(equal to Supply Voltage) Dimension: Install Guide: 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 Information: Cable colour: Red 3-5V Yellow/Blue Signal Black GND Connections: Servo pins always have the right pins: 5V,Ground and Signal. Most endstop pins will have the same 3 pins, and sometimes only Signal and Ground. If you only have these two, there should be a 5V somewhere else on your main board. In theory you can choices any input pins on your main board for signal. Expansion: If you want install more than one unit on same printer just connect the unit one to each other then connect to the main board at the end.They just parallel connection on the circuit Level. So the signal output can’t tell which one is run out actually but you can check the flashing LED on the unit to find out.
