Print Quality & Calibration Guide

Start with the Print Defect Visual Glossary if you are not sure what the defect is called.

Ringing on tall parts

The A1 moves the whole bed, so tall and narrow parts can wobble. Re-run vibration compensation, make sure the printer stands on a solid table, and for very tall models lower the outer-wall speed or add a brim.

First layer not sticking

1. Wash the textured PEI plate with warm water and dish soap — fingerprints are the number-one cause.
2. Make sure the plate type selected in Bambu Studio matches the plate on the printer.
3. For PETG on smooth PEI, apply a thin layer of glue stick as a release agent. More tips in Bed Adhesion Techniques.

Stringing

Dry the filament first. Then run the Flow Dynamics calibration in Bambu Studio for that filament and save the result to a custom filament profile.

Layer lines look uneven

Check that the filament is not catching on the spool holder or AMS lite. Uneven pulling resistance shows up as banding.
