Filament Runout Sensor for Scalar 3D Printers

Description

DescriptionThis plastic part is a Filament Sensor Module for Scalar 3D printer.It allows to detect the end of filament and trigger a filament change on firmware side.Updates2017.04.02 - Minor fix, the button could sometimes get stuckCompatibilityCompatible with both 1.75 and 3mm filamentThis is compatible with Marlin RC8 firmware.Just un-comment the runout sensor section on the firmware (near line 776)Stuff neededAll you need is a mechanical switch with a roller at the end such as this one:http://3dmodularsystems.com/en/electronic/74-micro-switch-end-stop-with-roller-for-3d-printers.htmlWiringOn ramps board you need to connect one end of the switch to the last servo pins (SERVO3_PIN).One wire is to be connected to the Signal pin and the other wire is to be connected to the ground pin.3D Modular SystemsEvolutive 3D Printers You enjoy it and want to help us with a donation: https://www.paypal.me/3DMShttp://www.3dmodularsystems.comTwitter: https://twitter.com/3dmodularsystemYoutube: http://www.youtube.com/c/3DModularSystems3DPrinters
