Filament Sensor

A filament sensor is a device commonly used in 3D printers to detect the presence or absence of filament in the printer's extruder. The filament sensor can help prevent failed prints and wasted filament by alerting the user when the filament runs out or breaks during a print job. The filament sensor typically consists of a mechanical or optical sensor that is mounted near the extruder. The sensor is designed to detect changes in the filament's movement or tension, and can send a signal to the printer's control board to pause the print job and alert the user. When the filament sensor detects a filament outage, it can send a signal to the printer to pause the print job, allowing the user to load a new spool of filament or fix any issues with the current filament. This can help prevent failed prints and wasted filament, as well as save time and effort in reprinting failed prints. When choosing a filament sensor for your 3D printer, it's important to consider the compatibility with your pr
