Couscous

@Siff
yup, and I would also add that you can see the pressure is (consistantly) inconsistant, plastic is not flowing freely

I dont know this printer, but this looks like a massive Y axis shift because of a weak Y motor when any problem happens (i used to fix this by tweaking the stepper and get a better couple)

@lime
I did it some time ago, and I likely did it in Cura (it fixed extrusion consistency and stringing for sure, especially with some special matte PLA)
I thought it made sense that extrusion pressure would be related to material density, now Orca may handle it differentlyn, or i’m totally wrong (and fixed it without knowing how 😄 )

@lime
I’ve had issues with PETG that were fixed by giving precise density to orca for example

@lime
I meant the information that comes with the filament, density of the material is given on the label on your spool or on the website, like here for example in this page https://www.elegoo.com/products/petg-translucent :

@lime
also if you can, check your filament density and compare to what is specified in orca
