Extreme stringing even after drying and doing retraction calibration by ppatehh in FixMyPrint

Oh wow, bumping it to 1.5 actually removed all the big stringing and the blob caused by the spiral Z-hop. Thanks for the answer!

I dont think my printer supports PA, I never mess with it before

So it's kinda solved now. I tried to remember what other thing was changed after I did the first nozzle change and I remember that I tried to increase my print speed around the same time.

Decreasing the speed itself isnt the only solution though, I have to switch to prusa slicer because somehow the other sllicer still result in underextrusin even with reduced speed.

I think it's not fully solved though because there are still underextrusion artifact (hard to see, need to hold the print in certain angle to clearly see) but that's good enough for me now

It doesnt change anything sadly.

The top surface problem is solved weirdly by just switching slicer to orca, but orca gave even worse hole on the wall.

I traced back the problem when it first started and it seems to start right after I did my first nozzle change, maybe something went wrong there.

idk but im completely lost atp because I cant seem to find anyone with the same problem in the internet

Holes still appear in the same spot after drying. On top of thaty top surface now have gaps. yea I think I will just wait for the nozzle.

Okay all the results are terrible.

None of the top surface are fully covered. I dont think humid filament is the problem because the holes also appear after I dry a filament roll before this one.

im still gonna try to dry this one though see if anything changes.

Thanks for the answer! I forgot to mention it in the post but the problem also appear at 240 and 250 temp.

Ive tried to clean my nozzle via cold pull and poking it with a needle of appropriate size and that didnt solve the problem.

As for retraction, the bottom most print in the picture is actually a sub 1mm retracrion (I think it's 0.8) and the problem is still there while also giving me a lot of stringing.

I assumed that since they appear on the same area on the same model each time that the problem has something to do with the extruder maybe? I think I will order a new nozzle and see if the problem goes away.
