AstroPrint
Filament sensor
Can you guys add a filament sensor. I am thinking the main idea would be that the filament would run over a Micro Switch and close the circuit when there is filament and would open the circuit when there is no more filament and stop the print.
Actually, I built the simplest possible airprint detector today for my dual extruder makerbot. I took an optical usb mouse and put it beside my filament reel, as the spool moves, I get movement in my evdev events in python. That's it. I'm not joking, I can detect filament out and airprint in immediately. Let me know if you guys want to see my tragic code and pull it in to Astroprint somehow.

Image included to inspire, I made no effort to clean the code or make the mice look special.
Filament runout sensor is one of 2 plugins that made me make the conversion back to OctoPi. I miss my Astrobox, please support this sort of plugin.
