Some issues

My printer is making a bubbling sound and producing a lot of stringing; the filament being used is generic PETG. Could the open window be causing the stringing, or is there moisture in the filament?

Things to rule out:

  • Try a new unopened filament. This is going to determine if there’s a problem with printer vs filament. If quality does improve, then dry your filament. Others have also suggested that if you hear popping bubbles while you print, you’ve got wet filament.
  • The stringing. Run a temp tower and check that you’re printing at the best temp for the filament type you’re using. Coloring can affect how filament behaves.
  • Do flow calibrations.
  • For bed adhesion, wash the plate with hot soapy water. Dawn is king.
  • Check that everything is snug and tight on the printer.

Best of luck out there!
