My printer had been working pretty well for a long time. The quality had started to slowly degrade, but I still considered it well within acceptable tolerances. Then, finally, I started experiencing intermittent clogs. I tried cleaning the nozzle as best as I could, soaking in acetone (well, my girlfriend’s nail polish remover), heating the nozzle to 250, changing print settings, etc. Still the problem persisted. As an amateur mechanic, this is when I start replacing parts. A quick Amazon search for bowden parts found the tubing and the clamp thingies on the ends for pretty cheap and another search found the 0.40mm nozzles (something like $5 for 10).<\/p>\n\n\n\n
I got the hot end off of the carriage, then heated it to 250 and pushed the latest clog through. I installed the new teflon tube and noted that it’s supposed to push down into the hot end quite a bit. I got the hot end cleared so the tube would sit properly, installed the new nozzle and reassembled the whole thing. <\/p>\n\n\n\n
It loaded the filament beautifully and never did the stepper kickback that it had been doing. Now it is printing Benchy perfectly (well perfect enough for me).<\/p>\n\n\n\n
Moral of the story is to occasionally just replace that nozzle. They’re cheap, it’s an easy job and it will save your prints.<\/p>\n","protected":false},"excerpt":{"rendered":"
