Purpose
Different versions of popular slicers can generate G-Code in unexpected ways, not as the creator intended, leading to poor print quality. This quick test model helps you identify three specific issues I have personally encountered:

How to use

• Bambu Studio
  Simply slice the model—printing is optional. Inspect the preview for the three problem zones described above.
• Bambu Handy
  Print the test model (it’s very fast). Check the printed part for the issues.

Description	Expected result	Incorrect result
Wrong default support type When you simply toggle supports on in Bambu Studio they have tree(auto) type, but in other slicers they may be generated as normal(auto)
Modifier not applied The sample model contains a modifier that removes top layers and increases wall loops. In certain versions (Bambu Studio 1.10.2.76) the modifier is silently ignored, which can weaken the print.
Classic infill generator instead of Arachne The test model is sliced for the Arachne perimeter generator (should show two top‑surface lines). If you see three lines, Arachne was downgraded to Classic—an error I’ve seen happened when uploading a project to MakerWorld.

What to do if you spot a problem

1. Update to the latest version of Bambu Studio or Bambu Handy.
2. If the problem persists, please write a comment with screenshots/photo, and provide the slicer name and version.
   • I will check the problem.
   • I may refresh older print profiles.
   • If needed, I will try to forward a bug report to Bambu Lab support.
