Bambu Studio 2.8.0.50

Bambu Studio V2.8.0 adds features such as the Assembly Guide generation tool and counterbore hole bridging, along with a number of improvements and bug fixes. You can download the Flathub version for Linux from Bambu Studio on Flathub ↗. The Flathub version is maintained by @hadess ; thanks to him for his outstanding work.

Note: 3MF files saved in the Beta version are temporarily not supported for upload to MakerWorld. If you need to upload, please use the official release version.

Features

Supports designing and generating model assembly guides directly within Studio

Step-by-step assembly guide for complex models (new): Import a STEP file to automatically split it into assembly steps, with visual guidance to help you understand how parts fit together.

• Edit the objects/parts of each step through the object tree
• Two viewing modes — X-ray and "Show current step only" — for easier positioning
• Supports exploded-view animation and multiple annotation types (snap-fit / rectangle / text); generate an assembly walkthrough animation in one click, with a unified camera view and auto-layout
• One-click export to PDF / Markdown / MP4

Added Counterbore Hole Bridging Support

A new "Counterbore hole bridging" option under Quality → Advanced. It lets you print counterbore/countersunk holes without supports, with three modes:

image

• None: Default behavior; no bridging is applied.

image

• Partially bridged: Bridges only the overhanging ring region while leaving the center open.

image

• Sacrificial layer: Generates a single full bridged layer over the entire hole as a sacrificial layer, providing a base for the layers above.

Many thanks to @szc188 for the contribution.

Improvements

Time-lapse Video Quality Improved Across All Printer Models

Optimized the tool head landing point to prevent camera shake caused by uncertain landing positions, and enhanced the viewing experience of time-lapse photography videos. Ensure that the tool head during time-lapse photography is as far away from the camera as possible to avoid any obstruction.

Other Improvements

1. For the H2D, this Beta adds a foreign object detection toggle and enhanced curve-planning support, and improves circular hole compensation.

⚠️ Minimum required firmware version: 01.03.50.00 (H2D)

1. Fixed an issue where dialogs popped up repeatedly in some not-logged-in scenarios.
2. Added a confirmation dialog when clicking to clear "Recent files."
3. Updated the price information for some filament presets.
4. When the flushing-volume matrix automatically calculates flushing volumes, it now accounts for switching between official material types: for example, switching between PLA and PETG automatically increases the flushing volume to prevent insufficient interlayer adhesion.
5. Added support for the 3Dconnexion SpaceMouse Pro Wireless Bluetooth Edition. Thanks to @mpaperno for the contribution.

Bug Fixes

1. Fixed an issue where the Bridge flow under Quality Settings did not update the G-code bridge line layer height when Top Z distance was set to 0. (#10127 ↗)
2. Fixed an issue where settings could not be copied and pasted from one part to another. (#10996 ↗)
3. Fixed an issue where G-code files generated by earlier Studio versions lost color painting (multi-color) information. (#10984 ↗)
4. Fixed an issue where Studio crashed when opening a file from MakerWorld. (#11037 ↗)
5. Fixed an issue where the incremental numbering in "Fill with copies" overflowed and became incorrect after exceeding 99. (#10492 ↗)
6. Fixed an issue where modifying a negative part reset the original object's location. (#10191 ↗)
7. Fixed an issue where normal support expansion created extra isolated support structures. (#11110 ↗)
8. Fixed an issue where the remaining drying time was displayed in an incorrect time format. (#11171 ↗)
9. Fixed an issue where the slicing tips for shrinkage-prone filament did not follow the same display logic as other tips.
10. Fixed an issue where, after enabling Alternate Extra Wall, changing the wall loops count and saving the process settings caused Bambu Studio to crash on the next launch (failing to open). (#11178 ↗)
11. Fixed an issue where the bridge speed set individually for each part did not take effect.
12. Fixed a use-after-free issue with the WebView async callback on macOS. Thanks to @BenJule for the contribution.(#11052 ↗)
13. Fixed a crash when loading objects with no instances. Thanks to @BenJule for the contribution. (#11053 ↗)
14. Fixed a typo (percision → precision) in the device manager for motion calibration. Thanks to @mvanhorn for the contribution. (#10871 ↗)
15. Fixed an issue where the Edit Filament dialog was not centered on its parent window. Thanks to @BenJule for the contribution. (#10835 ↗)
16. Fixed security vulnerabilities in the undici, js-yaml, and @babel/core dependencies. Thanks to @BenJule for the contribution. (#10877 ↗)
17. Fixed a compilation issue caused by undeclared boost::prior. Thanks to @hadess for the contribution. (#11059 ↗)
18. Fixed an issue where the AMS slot edit icon click detection missed the Y-bound check, causing inaccurate clicks. Thanks to @BenJule for the contribution. (#10859 ↗)
19. Fixed punctuation and grammar errors in UI warning/tip strings. Thanks to @BenJule for the contribution. (#10813 ↗)
