Description
This 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.
Updates
2017.04.02 - Minor fix, the button could sometimes get stuck
Compatibility
Compatible with both 1.75 and 3mm filament
This is compatible with Marlin RC8 firmware.
Just un-comment the runout sensor section on the firmware (near line 776)
Stuff needed
All 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.html
Wiring
On 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.
