Print Quality Issue final layers

[Bouboo]

Hi all,

I’ve been using my BambuLab X1C Carbon for months without any issues, but suddenly, my prints are turning out with rough final layers and noticeable trenches, as if the nozzle is too low. I’ve tried cleaning the nozzle, performing a cold pull, and even replacing the hotend, but nothing seems to work. Any suggestions on how to fix this? I’m using bambu lab PLA

Thanks in advance!

Welcome to the forum.

It looks like you are heavily over extruding. Have you calibrated your filament?

Hi there,

Thanks for the answer and yes I did but in fact the weirdest thing about my problem is that it happened overnight without any reason I have an ams I haven’t changed my fillament I haven’t done anything.

I would first try recalibrating your filament. Also check to see if in fact the filament coming off the spool is the correct size. There is always the possibility there was a problem during filament manufacturing.

Often unexplained issues seem to be solved with a factory reset. Might be something you can try if you can’t figure out the issue.

Hey,

Today I have reset and fully calibrated it and the problem remains the same. If you have any other ideas

I noticed something similar on a very large, flat print near the back-right corner. I was wondering if somehow the filament was getting bound up in the extruder tube as that corner is where is it “bunched up” the most as the head moves around.

Like you, this popped up recently without any changes on my part.

Hey,

For those who will have the same problem and found this topic.

For me the solution was to clean my extruder my old filament did a mess in it, I’m adding the link to the guide.
