How do I fix spaghetti / print detached mid-print?

  1. 1

    Improve first-layer adhesion: clean the build plate with IPA, add a brim (5–8mm), and increase first-layer bed temp by 5°C. Spaghetti almost always starts with the part detaching from the bed.

    Setting: others.bed.brimType

  2. 2

    Enable Bambu's Spaghetti Detection (AI) in printer settings if available. It uses the camera to detect print failures early and pauses the print before wasting more filament.

  3. 3

    For tall/thin parts, reduce print speed and acceleration, or add a brim. High-speed direction changes create lateral forces that can knock over parts with a high center of gravity.

    Setting: speed.accel.normalPrinting

Pro tip: Select "Good Cosmetics" above — the recommended first-layer and brim settings dramatically reduce the bed adhesion failures that cause spaghetti.
