Filament Runout Sensor for Scalar 3D Printers

thingiverse

This plastic part is a Filament Sensor Module for the Scalar 3D Printer. It allows detection of filament end and triggers a change on the firmware side. The module updates with minor fixes, ensuring smooth operation. The sensor is compatible with both 1.75mm and 3mm filament, making it a versatile addition to any 3D printing setup. It works seamlessly with Marlin RC8 firmware. To set up the Filament Sensor Module, simply uncomment the runout sensor section on the firmware near line 776. This will enable the module's functionality. All you need is a mechanical switch with a roller at the end, available from 3D Modular Systems. The product number is listed below: http://3dmodularsystems.com/en/electronic/74-micro-switch-end-stop-with-roller-for-3d-printers.html To connect the module to your Ramps board, follow these steps: Connect one end of the switch to the last servo pins (SERVO3_PIN). One wire is connected to the Signal pin and the other wire is connected to the ground pin. At 3D Modular Systems, we're passionate about evolutive 3D printers.
