Bought a bunch after seeing the issues I had over the Chinese new year. So I paid up front for some spares for my K2 printers and today I used number 5 replacement due too PTFE hose connector letting go last week since then I had many failed prints. All ending in jams. Why? Probably because the nozzle has teeth in it.
So tired of this crap my hot end it buggered couldn’t swap the nozzle could not remove it. The nozzle is completely locked tight into the hot end
How do I know metal was in the hot end hehe because extruder housing jammed hard with petg stuck
Anyway here is extruder housing 4 and 5 great day!!
