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.

have you done a temp tower with it? maybe it doesn't like your temp settings.

I've used old filament plenty of times and usually it just gets stringy

i think yours is a timing or temp problem

I've tried multiple temp towers but they all failed because of the underextrution. So I tried benchys with with 190 and 220°C and have seen little difference. Then I just stuck to 200°C for no other reasons then I've used it before

Pretty bad underextrusion. Is the filament drive slipping?

if it only happens with that filament, its probably just that.

you could try some of the drying methods but that doesn't look good at all

if you're sure the filament is good then you want to look at the print settings and physical tensions on the belts and gears. maybe you need to look at the spot where your printer is located. can it add any wobble? one trick in the prusa community is putting your printer on a heavy flat yard paver stone and a thin foam under the paver
