Run a quick diagnosis

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

Start diagnosis

Likely causes

Support gap is too small
Increase Z contact distance or interface gap in small steps.
Interface is too dense
Reduce support interface density or number of interface layers if removal is more important than underside quality.
Temperature is too high
Lower nozzle temperature a little so support contact points do not weld as strongly.

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.
