I bought my MK3 back in 2018 an i printed about 9,5 KG of filament without any major issue.
Since two month i start to get problems with the extruder stop extruding resulting in unfinished prints. I thought it was a problem of a clogged nozzle so i changed and it get a bit better. I ordered a new heater with a bunch of nozzles. The problem came back. I changed the heater (new barrel / new nozzle 0.4).
Still the extruder stops extruding.
When it stops it starts with the deep clicking noise paired with “heavy” vibrations on the printhead.
I tried different filaments (good german brand) wich always print very well, the filament is running freely.
I mesured the gear on the stepper motor i get readings on my digital calliper from 9.12 to 9.14mm.
I guess the gear is worn out.
Do i need a new extruder or is there another way to solve the problem? I allready have a new heater and my old one is still working.
