Ensure that your prints never fail because of low or broken filament with this Filament Runout Sensor for TAZ Workhorse/TAZ 6 3D Printers from LulzBot. The sensor can detect when there is no filament and will halt printing. In addition to an automatic heating system and idle nozzle heating time-out, you can rest assured that your TAZ Workhorse/TAZ 6 will be ready to continue printing a job when you are. The sensor is compatible with both 1.75mm and 2.85mm filaments, but please note that the sensor is not able to detect jams directly in the tool head.
