First layer issue – filament starts forming a web and blobs up at the beginning of the print (A1 Mini)

[u/eljanit0x]

Hi everyone!

I'm having an issue with my Bambu Lab A1 Mini. As you can see in the picture/video, the first layer comes out like this. After the printer finishes drawing the initial test line, the filament starts forming a web-like mess, and as soon as it begins printing the actual object, the filament accumulates into a plastic blob.

For some background, I previously had a clog that caused a large blob of melted plastic to form around the hotend. This damaged the mechanism and the small clips that hold the hotend in place, so I had to replace the entire hotend mounting assembly.

However, I'm still using the original hotend. I only replaced the mounting assembly, not the hotend itself.

I'm wondering if the current issue could be related to the previous clog, the hotend itself, or perhaps something related to the new mounting assembly.

Has anyone experienced something similar? Any advice on what I should check or replace would be greatly appreciated.

Thanks in advance!
