I haven’t had issues printing with the Sainsmart TPU (Hardness 95a) in the past but recently I have issues where the filament is bunching up in the extruder.
I’ve dried the filament over night in my esun drier, leveleled multiple times and disabled the retraction settings, but I still keep having the issue.
The filament is not pushed against the extruder gear by the idler pully. It just ends up bunching up and not extruding.
Any idea what I can do?
