Filament Width Sensor with Arduino uno and Thickness-Gauge

This is a sensor that measures the width of plastic filament in real time as it goes into a 3D printer or a filament extruder. It works in a real time mode. This solution is compatible with Lyman extruder. You can download sources from https://github.com/NerdDoc/Filament-Width-Sensor-with-Arduino-uno-and-Thickness-Gauge. For editing PCB you will need Sprint Layout 6.
