I'm beta testing the new filament monitor from Duet3D. It's a nice compact device that monitors filament feeding into your extruder and if the filament runs out or jams in the hot end, the monitor will tell Duet to pause printing. Here it is mounted on the Micro extruder on my UltiBots D300VS delta printer. I modified the printed case so I could attach a short length of 2mm ID PTFE to the bottom of the monitor. This short tube fits into a mating hole on the top of the extruder.
I'm calibrating the monitor now and then it will be ready to watch my filament. I'll report back as I gain more experiance.
