• Preserves the original filename whenever possible.
• Added detailed download filename diagnostics to the Project Report and Error Report.

Fixed

• Fixed converted file downloads failing for certain Unicode filenames that could be rejected by Chromium-based browsers as Invalid filename.

v1.5.0 - integrated conversion error reporting

Added

• Built-in conversion error handling with stable error codes
• One-click copyable error reports
• Detailed diagnostic reports in the browser console

Improved

• Improved conversion button alignment and text centering

v1.4.1 - Improve Orca compatibility and fix project warnings

This release further improves compatibility with both Snapmaker Orca and OrcaSlicer.

Fixed

• Fixed an OrcaSlicer crash caused by empty filament_adaptive_volumetric_speed values.
• Fixed invalid configuration warnings caused by missing filament_self_index values.
• Fixed filament_flush_temp warnings when opening converted projects.
• Fixed compatibility warnings caused by negative raft_first_layer_expansion values.

Improved

• Improved compatibility with MakerWorld projects containing many filament slots.
• Additional reverse-engineering based compatibility rules have been integrated to make converted projects behave more like native U1 projects.

v1.4.0 - OrcaSlicer Compatibility

What's new

• Added optional OrcaSlicer compatibility mode.
• Added support for importing custom OrcaSlicer printer profiles.
• Redesigned the printer profile management section in the extension settings.

The converter can now generate projects for either Snapmaker Orca or regular OrcaSlicer, depending on the selected compatibility mode.

Custom printer profiles for both slicers are stored separately and can be imported directly from the corresponding slicer profile folder.

v1.3.0 - Multi-plate support and filament fixes

This update introduces one of the biggest improvements to the converter so far.

New: Automatic Multi-Plate Positioning

MakerWorld projects containing multiple build plates are now automatically repositioned for the Snapmaker U1.

The converter now compensates for differences in build plate size, center position and plate spacing while preserving:

• Object positions on each plate
• Rotation and scale
• Relative spacing between all objects
• Plate layout

Single-plate projects remain completely unchanged.

For additional safety, every plate is fully validated before any object is moved. If a plate cannot be adjusted safely, the entire plate is left untouched.

---

Improved Filament Preservation

Improved preservation of filament-specific project settings when keeping the original MakerWorld filament profiles.

This fixes issues where settings such as Maximum Volumetric Speed and other filament parameters could be read from incorrect positions in some MakerWorld projects.

---

Better Converter Diagnostics

The converter report now provides additional information for multi-plate projects, including:

• Detected plate grid
• Center offset
• Grid spacing difference
• Maximum object movement
• Adjusted and skipped plates
• Unresolved instances

---

As always, thanks to everyone testing the extension and reporting issues. Your feedback continues to improve the converter with every release!

v1.2.0 - Major performance improvements

Performance

• Significantly improved conversion performance, especially for very large MakerWorld projects.
• Reverse-engineering diagnostics now run only when Deep Debug Report is enabled.
• Optimized ZIP compression settings to reduce conversion time while keeping output files compact.

Improvements

• Reorganized and simplified the converter report.
• Added a clearer conversion time display.
• Improved performance diagnostics for easier troubleshooting.

v1.1.1 - Fix multilingual 3MF detection

Fixed

• Fixed 3MF download detection on non-English MakerWorld languages.
• Improved alignment of the conversion button content and loading icon.
• Replaced the misleading "select a print profile first" error with a more accurate 3MF download option error.

Build

• Browser packages now include the README, changelog, privacy policy, license and third-party notice files.

Documentation

• Added Chrome/Chromium update instructions to the README.
