Dual Action Filament Runout Sensor

Description

The Dual Action Filament Runout Sensor detects when filament is inserted. This sensor not only detects when the filament pulls through and runs out, but also if the end of the filament is bent (or has tape on it), gets caught on the inlet, and stops feeding. With the proper length PTFE tube on the inlet, this sensor can also detect if there is a tangle on the spool.
