Guys,
My Monoprice Voxel just started having feed issues. Printer is pretty new - only couple of months old. Everything was perfect until last night.
After about 40 mins of printing, a noise can be heard that is clearly coming from filament feeder. Visually gears are not moving at that time. After few seconds printing continues.
Any idea what might be happening?

Here's URL to video: (apologies for sideways video, I had to quickly grab my phone to start recording)
