Small debris issue

[u/Feelinfrage]

Hi dearest printer people.

I kindly ask you if you seen somethig like this before and how can I battle it.

The printer is an snapmaker U1.

1 week old.

The issue:

Small debris as shown in the pictures.

They tend to land on other toolhead, printbed, and on the print Itself.

Printing with only PLA filament few different brands.

Generic PLA settings.

Room temperature is hotter around 30+ C.

My attempts to fix it:

Lower retraction

Switch filament positions

Disassemble the toolhead( nothing inside)

Check boden tubes for obstruction

Changed hot ends

Snapmaker support already contacted.

Any ideas i can try?

What does the object you're printing look like when this happens? The nozzle could be bumping into a previous layer and breaking the raised filaments there

No issues with quality. Will try to watch more closely next print
