Im working with an old reprap cotroled directly with an Laptop with cura. Filament is RS-Pro (2325395) Pla though. Open around 4 weeks ago but i have this problem in some capacity since i have this Filament. Before i had some really old pla which snapped all the time because it wss so brittle. Is this really just shitty Filament? Help/ Insight would be much appreciated.
Edit: solved. Disabling the retraction worked (as a temporary fix). The Spring of my extruder is too strong so my extruder was eating my filament especially in high retraction areas. The results with my old and hard filament were better because it was so hard the extruder didn't eat it. Picture is in the comments. Thanks everyone for your help.
I've had partial clogs that manifest like that.
Cold pulls (several) ended up resolving my issue.
my best explanation was, that there was some debris in the nozzle, which would sometimes (nearly) seal the nozzle, and at other times be retracted with the filament, get stuck somewhere else and filament flows freely.
Yeah, I don't use much PLA but this looks like a partial clog, you can see that where you have long stretches of extrusion it works fine, but when it starts retracting it clogs.
It could very well be that it's clogging BECAUSE it's shitty or wet filament, tho. Is your nozzle screwed in correctly, heatbreak too, etc?
I exchange the nozzle for a new one but no luck Disabling retraction worked. But thanks for your suggestion :)
