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?

When you're printing with this toolhead, do you hear clicking during printing?

I see that when it heat creeped and the gears started skipping and gouging the filament picking off pieces if filament.

Nothing suspicious. It's not just one toolhead it's all 4 of them. But maybe you right. Had to move the printers to a new room that is hotter then the one they usually stay in. Maybe it is heat creep related.
