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.

    That’s what extremely wet PLA looks like.

      Yeah thats why i bought new Filament but my point was i never had the underextrusiom with the old one just with the new one Turns out my Extruder sprimg was to hard so my extruder gear ate my Filament. The old Filament was so hard this wasnt an issue

      But thanks :)

    Has the printer been used recently and put out good prints? Has anything about the setup changed including a slicer update or different slicer?

    I have two knee jerk reactions

    Is there an under-extruded section of the print, similar to the corner closest to the camera on the lower section of the print, on the top section of the print? You might have a retraction/priming problem. A quick retraction test print would make this pretty obvious.

    You might have had a partial clog that resolved itself, but the fact that the extrusion issues change with the topology of the design makes me want to suggest something else. Try the print again. If you get the same outcome filament isn’t the primary cause.

    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.

      I exchange the nozzle for a new one but no luck Disabling retraction worked. But thanks for your suggestion :)

    Print i did immediately before. Main differences no supports and less Variationen in horizontal Crosssection ?

    It’s your filament wet? Have you replaced the nozzle? What’s weird is the edges appear to look like oozing but you’ve done a temp towers.

    Looks like wet filament to me. Those pock marks are what happens when the moisture immediately evaporates to steam and bursts when it hits the nozzle.

      Yeah seeing the original I suspected retraction settings since it was mostly in places with lots of retractions.and long paths even out and look smooth.

      This fixed the under extrusion which seems to confirm it’s a retraction problem but disabling it entirely you’ve got those oozing artifacts where moves happen.

      I’d suggest using a small value for your retraction and probably take the time to use teaching tech or ellis’ tunning guides to tune your retraction settings.

    I’d wonder about the model or slicer. You had great printing above and below that. Unless you had a nozzle problem that cleared itself up, that’s a weird way to go bad right at that transition, and it’s very symetric on that section.
