Filament out sensor feature ?

I was looking at the new Makerbot v5 and saw that the smart extruder has a filament-out sensor that pauses the print.

Could we do such thing in the Firmware, or the host ?
For instance by guiding the filament through a light barrier which gives a 'high' signal to any pin at the ramps (or Arduino) when the light comes through due to filament out,
after which the firmware, or the host program issues a Pause ?

Pause, with the hotend at the home position can last forever, giving time to change filament and resume...... Maybe use an unused end-stop for this ?

Try latest dev version. The jam detector can also be used as out of filament sensor. With latest dev this hopefully now works in that case also correct.

Sounds promising.
Is the jam detector function somewhere documented ?

Check docs folder on github. There is a file describing it a bit.
