Boogers?

Can anyone tell me what the technical term for this would be? And what settings I would need to change to get a cleaner print? The only thing I can think to call it is boogers while it's printing.

My prints are failing about this point. I'm not sure but it might be the extruder motor overheating.

Basically called it right @ boogers. Happens when material builds up on the outside of the nozzle and gets deposited when it gets to a certain size or the head changes direction. You could try adjusting/lowering your extrusion multiplier; also make sure you are setting the correct filament diameter from the supplier - 1.75 mm is the standard spec but it can vary, eg. 1.72 mm.

It also makes a difference what nozzle you have to prevent buildup - a hardened & coated nozzle in a silicone sock is going to greatly alleviate that compared to just a generic $1 brass nozzle from amazon.
