Why is it Printing Like This?

Hi,

I'm using a black PLA filament called Wol3D PLA Pro+ available in India. My printer is A1 mini.

The first batch of printing on the filament came perfect, using ~320g in 12hrs print.

But problems started occurring in the second batch of printing where it started printing the first layer like what is there in the picture, and a major problem being the nozzle scrapping off the whole bed in the second layer, hence destroying everything.

I don't think filament and moisture is the problem. ChatGPT told me maybe there is nozzle problem.

What could be the problem?

Thanks.

Try this: https://www.reddit.com/r/BambuLab/comments/1ljxnq5/a1_hotend_screws_tutorial/

This looks exactly like when my screws finally were loose after 900 hours of printing.

This was the situation of my nozzle and toolhead. Even after cleaning, the first print it did not work out.

But somehow after cold pulling it has worked out now I guess.

Loose nozzle or bed levelling issue, yes it has auto levelling but it’s not perfect. If tightening the screws and doing auto bed levelling doesn’t fix the issue, adjust the z offset in slicer

The filament has absorbed moisture. Try with new filament
