Kromacut v3.0.0
Installation
macOS:
- Download the .dmg file for your Mac:
- Apple Silicon (M1/M2/M3): *_aarch64.dmg
- Intel: *_x86_64.dmg
- Open the DMG and drag Kromacut to Applications
- Remove quarantine (required for unsigned apps):
sudo xattr -d com.apple.quarantine /Applications/Kromacut.app - Launch from Applications
Windows:
- Download the -setup.exe installer.
- Run the installer and follow the prompts. The standard Windows installer includes the Microsoft Edge WebView2 bootstrapper, but requires internet access if WebView2 needs to be installed or updated.
- For offline Windows machines, download the *_offline-setup.exe installer instead.
- Launch Kromacut from the Start menu
Linux:
- Download the .AppImage or .deb file
- For AppImage: chmod +x Kromacut*.AppImage && ./Kromacut*.AppImage
- For Debian/Ubuntu: sudo dpkg -i kromacut*.deb
What's Changed
Added
- In-app user documentation - Added a bundled Markdown Docs view with a conventional guide table of contents, per-page tables of contents, stable heading links, header brand navigation back to the app, cross-document navigation, and end-user guides for the image-to-3D-print workflow
- 2D image resolution resize - Added a 2D Resize Image tool for downscaling the current image by percentage before color reduction or 3D model generation
- Filament profile renaming - Added a rename action for saved Auto-paint filament profiles
- Pre-build model size estimate - Added an estimated 3D model size to the Pixel Size setting, shown as a blue input-height estimate beside the input when space allows so users can preview footprint and stack height before building the model
Changed
- Project license - Kromacut is now licensed under
AGPL-3.0-onlyinstead of MIT so redistributed or hosted modified versions must stay open under the same copyleft terms - Web metadata - Improved the page title, search description, canonical URL, social preview tags, and web app manifest metadata for hosted Kromacut pages
- Filament profile extension - Auto-paint filament profile exports now use
.kfilby default while continuing to import legacy.kappfiles - Smooth meshing performance - Smooth mesh generation now uses one fast welded-grid algorithm with deterministic boundary-chain smoothing in a bounded sub-pixel envelope and fan-triangulated caps instead of contour tracing and cap cleanup, avoiding hangs and browser memory blowups on complex image layers
Fixed
- Desktop update notices - Fixed the Tauri desktop update checker so it runs without requiring the disabled global Tauri API, reports when the release endpoint differs from the installed app, uses a solid notification surface, and opens the GitHub releases page from the download button
- Windows desktop image drop - Disabled Tauri's native webview file-drop interception so dragging image files onto the 2D canvas can reach the app's HTML drop handler on Windows
- Smooth meshing layer coverage - Smooth meshing now applies to every generated layer without mesher substitution state
- Smooth STL export - STL export now preserves smooth layer geometry instead of compacting smooth builds back into square-pixel heightfields
- Manual 3D build trigger - 3D print settings, including the smooth meshing toggle, no longer start or cancel preview mesh generation unless the user clicks Build 3D Model
