Extruder-Mount Filament Runout Sensor

Last crawled date: 6 years, 2 months ago

A simple optical filament-runout sensor that bolts between an extruder and the extruder motor. I had been using an optomechanical sensor and wanted to attach it over the extruder, but couldn't see a way to do that without the filament getting jammed up when the printer ejects it, so maybe this optical sensor will work better.
