Noise X axis A1

Bambu Lab A1 Series Troubleshooting
1

Hello!

I’ve just purchased my second Bambulab A1 printer, and from the start it’s been making a strange noise on the X-axis, which causes inconsistencies in the prints. I was used to the “perfect” prints from my A1 mini, so it’s very frustrating to face this issue on a new printer.

The noise becomes more noticeable in larger prints with circular or diagonal layers (I’m attaching a video), but the inconsistencies show up in all types of prints, becoming more pronounced in those types of models. I’ve included a video.

Test procedure:

  1. Used different PLA filaments (from Bambu and other brands) with various settings.
  2. Lubricated and adjusted the belts several times.
  3. Ran the maintenance tests and even did a factory reset.

The noise problem persists. If anyone else has experienced this, I would appreciate your help.
Best regards, and thank you.

I’m not an expert in FDM printerts, but I consider myself fairly advanced when it comes to technical matters and machine maintenance. After 20 days and trying everything suggested by tech support and the community, I decided to make use of the warranty and return the product. Bambu had no objections.

The issue was with wide movements—especially circular ones—and clearly defective first layers. With small parts that required little head movement, it seemed to perform better.
