3D Printer 1.75mm Filament Run Out Sensor Module with Cable, Auto Pause Detection and LED Indicator

Material Inspection Module Overview The Material Inspection Module monitors filament presence and pauses printing when filament runs out. It helps prevent failed prints by detecting filament loss and allowing the operator to filament before printing resumes. Key benefits Prevents failed prints by pausing automatically when filament is exhausted Simple integration with Lerdge motherboard via the Msensor port Works with other controller boards that accept a level detection input Durable design with wear resistant copper sleeve at filament inlet and outlet Features Wear resistant copper sleeve added to both material inlet and outlet for improved durability Visual indicator on Lerdge boards: green LED stays on while filament is present and turns off when filament is exhausted Direct wiring to Lerdge motherboard Msensor port for plug and play detection Level jump detection method for use on other motherboards: detection port reads level when filament is present and low level when filament is absent; a to low transition triggers a pause After the operator replaces filament the printer continues printing from the paused state Compatibility Designed for use with Lerdge motherboard using the Msensor port Compatible with other controller boards that can accept a digital level input for filament detection Uses standard level signal logic: when filament present, low when absent Package contents 1x Filament Detection Module Typical use scenarios Long duration prints where filament runout could ruin multi hour builds: the module pauses the job when filament ends and allows filament replacement before resuming Color or material change mid print: detect end of one spool and pause to install a spool to continue the print Remote or unattended printing setups where monitoring is limited: automatic pause on filament loss reduces the risk of failed prints and material waste Operation notes For Lerdge motherboards connect to the Msensor port and observe the green LED behavior during use For other boards wire the detection output to a suitable level input and configure the firmware to respond to a to low transition as filament runout This module provides a reliable, low profile way to add filament presence detection and automatic pause and resume functionality to compatible 3D printer control systems.
