Run a quick diagnosis

Answer a few short questions to get a prioritized fix list.

Start diagnosis

Likely causes

Dirty build plate
Wash the plate with warm water and dish soap. IPA helps between prints, but soap removes skin oils better on many PEI plates.
Nozzle height is wrong
Run bed leveling and adjust Z offset so the first layer is lightly squished but not transparent or scraped.
First layer is too fast
Slow first-layer speed to 20-30 mm/s and use a slightly wider first-layer line width for more contact area.

Prevention tips

Change one setting at a time and reprint a small test piece.

Keep filament dry and store open spools in sealed bags or dry boxes.

Clean the build plate regularly and verify the correct slicer profile before long prints.
