BIQU Filament Break Detection Sensor Module 3D Printer Accessories with 1M Cable for 1.75mm Filament Extruder Material Run-Out Detector for 3D Printer (Transparent)

❤【Function of Filament Detection Module】 To detect Filament in 3D printer run-out,pause detection,it automatically stops the 3D Printer when the filament runs out.Optimize the inlet port/outlet port of the material detection module, to reduce the resistance of the feeding material..
❤【Filament Break Detection Module】When there is material, the level signal of the detection port should be high level. When there is no material, the level signal of the material port goes low, and the system detects one. If the high-to-low transition is determined, the material is considered exhausted and a pause command is executed..
❤【Detection Method】The material detection module uses the level jump detection method..
❤【Filament Size】 It Suitable for 1.75mm Filament with 1m cable which making your printing work goes smooth and relieved..
❤ 【After-Sales Guarantee】We support high quality after-sales Service,any questions or feedback please contact us,no matter what refund or resend. We will satisfy with your request..

3-Pack 1.75mm 3D Filament Detection Module Run-Out Pause Detecting Monitor Filament Sensor for Ender 3 Pro CR-10 3D Printer and Lerdge Board

It includes 3pack filament sensor kit. 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..
The inlet port/outlet port of the material detection module are changed from the original metal copper sleeve to the rotating funnel opening design, which optimizes the resistance of the feeding material, makes the feeding smoother and eliminates the material/filament, and avoids the phenomenon of filament stucking and planing..
The arrow direction of the inlet position is silk screen, which is convenient for distinguishing the direction of the inlet and the outlet..
Used with Lerdge board: When there is material in, the green light in the module keeps lighting. And when the material is exhausted, the green light goes off, then the motherboard executes the pause command operation, after the replacement of the material, can continue to print. Wiring: Connect the module to the M-sensor port on the motherboard..
Used with other motherboards: The material detection module uses the level tra....
