Yes, sometimes the LLMs manage to write something that appears actually relevant and "in character" for a forum post. I wonder what the generic prompt for this might look like? "Briefly describe a personal experience with a related problem, and how the information in the thread helped you solve it?"

Wow... The AI's are getting more devious. I didn't notice the link spam until you pointed it out

Sometimes the smaller blobs are just a symptom of damp filament.

Some other machines have it. They do by camera and AI image processing. It is not completely reliable, especially if you print a model that is supposed to have stringy shapes.

When I print PETG, it outgasses and leaves fine streamers everywhere that look like candy floss (called cotton candy in some countries). My Bambu H2D keeps seeing these and they fool it into thinking the camera lens is dirty, which causes it to produce an alert instead of starting to print.

Once operating, it produces a false positive more times than it stops an actual failed part. (Which is annoying, it sends a notification to my phone and then I can see the camera and either tell it to skip the object, end the print, or resume, but sometimes I will be asleep etc and it will sit there paused on a perfectly fine print until I resume it next morning).

Overall it's nice to have and I leave it switched on, but it is in no way "fully working".

There are some open source solutions you can use if you do some DIY and hacking.

Not sure how my post got duplicated nor wound up in the wrong forum. But I do want to know why blobs can't be or aren't being detected. See link below.
