My Sovol Zero recently started printing very inconsistently. I’m getting clear under-extrusion — layers are thin, gaps appear, and prints fail.
Here’s what I’ve already tried:
different filaments
nozzle replacement
calibration and cleaning
checking the filament path
The problem remains. After opening the extruder, I noticed that the drive gear looks worn and slightly damaged. It seems to be slipping on the filament.
Has anyone experienced this on the Sovol Zero?
I’d appreciate advice on:
what exact gear/parts I should replace
any tips from people who already replaced the gear
The issue turned out to be a loose pin in the extruder gear assembly.
After inserting and securing it properly, the printer feeds filament normally again and prints are back to normal.
I just printed the file I posted above, I didn’t think I had an issue but installed it anyway.
Well, once I pushed the print over the connectors I found out mine was out maybe 2mm.
I think it might have been resting on the back of the board.
Anyway, it’s installed & maybe all Zero users should look into printing a fix.
