Run a quick diagnosis

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

Start diagnosis

Likely causes

Support density or pattern is too weak
Increase support density, add support walls, or switch to a stronger pattern for tall supports.
Poor support bed adhesion
Use a brim for tall supports and make sure first-layer adhesion is reliable.
Overhang cooling is not enough
Improve part cooling for PLA or slow down overhang sections.

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.
