Zero Toolhead doesn't unload filament,
Hello, I’ve equipped my Sovol SV08 with a Zero toolhead. The toolhead ran without any issues for 5 months, but now, all of a sudden, the toolhead motor rattles when I try to unload the filament. It runs without rattling in the other direction. I took the toolhead apart to see if something had gotten caught between the gears or if there was another obvious reason why the motor rattles during unloading, as if something were jammed. I then noticed that there were very small metal shavings stuck to the housing. Otherwise, I can turn the gears by hand without much resistance.
I’d like to hear your opinion on the extruder gears because I don’t know if they’re defective or if they’re still in good condition.
I also wanted to clean the whole thing and would like to re-lubricate it. What should I use—would Microlube GL261 work?
Would replacement gears from a different extruder work better?
I’ve attached a few pictures so you can get an idea of the situation.
Thanks a lot and best regards,
Volker
