Spaghetti Detected / Print Failed
Bambu Lab 3D Printer
Severity: ModerateWhat Does This Error Mean?
Spaghetti Detection means the printer's camera AI detected that the print has detached from the bed and is producing a mess of tangled filament. The printer pauses to prevent wasting more filament and to avoid potential damage. Clean up and restart the print with better adhesion.
Affected Models
- Bambu Lab X1 Carbon
- Bambu Lab X1
- Bambu Lab P1S
Common Causes
- Print detached from the build plate mid-print
- Poor first layer adhesion
- Build plate not clean (oils, dust)
- Part warped and lifted from the plate
- Support structures failed, causing the part to fall
How to Fix It
-
Remove the failed print and clean the build plate.
Scrape off the spaghetti mess. Clean the plate thoroughly with IPA.
-
Improve bed adhesion for the next attempt.
Clean the plate with IPA. Use glue stick or adhesive for difficult materials. Make sure the Z-offset gives a good squished first layer.
-
Add a brim or raft in the slicer for small or tall prints.
A brim adds extra material around the base for better adhesion. A raft provides a thick base layer for the print to sit on.
-
Check your support settings for overhanging parts.
If supports are too thin or too sparse, they can break mid-print. Increase support density in the slicer.
Frequently Asked Questions
What is spaghetti in 3D printing?
Spaghetti is the informal term for when a print detaches from the bed and the printer keeps extruding filament into the air. The result looks like a tangled mess of plastic noodles — hence the name.
Can spaghetti damage the printer?
Usually not, but it can clog the hotend or get wrapped around components. Bambu Lab's spaghetti detection catches it early to minimise mess.
