Under extrusion problem located

Recommended Posts

Lately I've had a problem with underextrusion on my UM2.

Something was causing a lot of backpressure, i could hear the extruder skip or hop on occasion, but i was having trouble finding it.

After experimenting with extrusion temperature, different rolls of filament, extrusion speed, cleaning bowden tubes and extruder gears and housing, changing nozzles, still underextruding.

Changed heatblock and heater/thermocouple, still problem.

 

Then I re-took the hotend apart and found this..

In case someone else is running into the dark corners exploring under extrusion, here is one more stone to turn over : )
