clogged nozzle

Post by kuper »

hello,
I have an extruder skipping steps because clogged nozzle.
the nozzle is clogged because of the small chamfer in the nozzle and the heat break,
which causes the filament to stuck in this chamfer.
Does anyone have any idea how to solve it?
photos attached,
thank you.

The chamfers aren't the cause of the jamming. Molten plastic will flow right past those.

The most common cause of jams is related to printing too fast for the current hot end temperature. A failed cold-section fan can also be a factor.
