Bambu Studio 2.3.0.70

V2.3.0 adds support for the Bambu Lab P2S ↗ and includes several new features and issue fixes.

New Features

Skip Part also skips unnecessary color-change flush

Previously, when skipping a single part, only that part’s geometry was skipped; material change flush related to that part still occurred. With this change, color-change flush and waste-tower paths associated with the skipped part will also be omitted, effectively shortening print time and reducing material waste. This feature is currently supported on H2S and P2S.

If blue parts A and C and black part B are on the plate and you skip black part B, older versions would still execute black flushand attempt to print black filament on the prime tower. In the updated version, after skipping black part B, black flush and related waste-tower paths will no longer appear.(In this scenario, comparing the new and old versions, print time drops from about 3.5h to 22min, and unnecessary flush decreases from about 60g to 0g)

⚠Note: Currently supported on H2S and P2S.

A1 / A1 mini support for AMS, AMS HT, and AMS 2 Pro

A1 / A1 mini now support AMS, AMS HT, and AMS 2 Pro with the use of the new AMS Hub for A1 Series ↗. When switching between AMS Lite and AMS/AMS 2 Pro/AMS HT, please also switch the AMS type on the printer screen or in Studio’s AMS settings.

⚠Note：

- Make sure Studio's version higher than V2.3.0.70 if you use AMS with A1/A1 mini.

- Minimum supported firmware (A1/A1 mini): 01.06.10.33

Boolean tool upgrade (Object-level + multi-part inputs)

Boolean operations can now be performed directly at the Object level without an extra “merge” step. Both Object and Part levels support multi-part inputs, making model editing more efficient.

“Avoid crossing wall” travel optimization

Inter-layer travel paths are further optimized so that travels also avoid crossing wall.

A new option 'Avoid crossing wall – include supports' is added. When enabled, detour planning for travel moves will also consider support distribution, further reducing stringing risk.This option is especially suitable for shoe-printing scenarios.

Overhang segmentation optimization

The overhang segmentation algorithm has been updated to prevent surface quality fluctuations caused by abrupt overhang changes, improving stability and consistency in overhang areas.

New Tutorials tab

The original Tutorials hub page has been refined: quickly access Bambu Academy, official tutorial videos, Bambu official filament guides, and more Bambu Wiki pages. A top-bar entry is provided for quick Wiki search.

H2D/H2D Pro remote nozzle identification

In Device→Printer Parts, click Refresh to trigger remote automatic identification of nozzle information for H2D/H2D Pro.The printer will move briefly during detection. Please wait about 30s for nozzle information to update.

Don’t slow down outer wall

When enabled, the outer wall is not throttled by the minimum layer time limit. This can yield better surface consistency in specific scenarios with Silk/Glossy type materials.

Extra length on restart

When enabled, an additional specified length is added on top of the normal unretract after a travel move. This option is recommended only for certain foaming filaments (e.g., Aero) .

Support: “Z covering XY” behavior

When enabled, if Top Z coverage conflicts with model/support spacing, the algorithm prioritizes generating supports directly beneath overhangs while maintaining a Top Z-consistent gap between the model and the support. This significantly improves support contact and removal on sloped surfaces, especially when using dedicated support materials.

Improvements

1. Modifiers support wall-order adjustments: You can flexibly adjust the order of walls locally, which is supported by Modifier and Height Range Modifier.

1. (Windows) Disable account auto-fill: Provides better privacy protection for logins in public places (enabled by default).

1. Clearer flush volume indications: More explicit display when flush values deviate from defaults; warnings when a flush value is set to 0 to avoid color-change quality issues from misconfiguration.

1. New build-plate presets: Added Engineering Plate and Cool Plate SuperTack for H2D/H2D Pro.

⚠H2D will support these two plates in the coming version.

1. X-series extrusion-compensation pattern optimization: Avoids overlapping with model paths.(github.com/bambulab/BambuStudio/issues/5682) ↗
2. Fixed Fuzzy Skin painted issues to prevent point distance and thickness settings can't be adjusted. Added a Disabled state and unified painted behavior with the previous None option.

1. CrossZag Optimization: Improved top/bottom skin closure for more natural texture transitions.
