New Features

• 1. Added Time-lapse Video Export (requires firmware V1.6.0 or later)
     To enable this feature, check the Time-lapse option in Print References before sending a print job.
     After printing completes, you can download the time-lapse video to your local device.
• 1. Added Print Preferences with support for Spaghetti Detection and Foreign Object Detection. These features help you identify anomalies during printing and take timely action.
• 1. Added a one-click auto-zoom and camera pan feature that instantly reframes the view to display all models in the scene or focus on the selected model(s).
• 1. Added Color Mixing Match Mapping, which automatically generates an optimal color matching solution within the reliable color gamut for multi-color models (especially those with more than 4 colors).
     Added a new process preset for color mixing: 0.10mm Color Mixing @Snapmaker U1 (0.4 nozzle).
     For guidance, refer to: Color Mixing Match Guide
• 1. Added support for Snapmaker PLA Full Spectrum, compatible with 0.2 mm and 0.6 mm nozzles.
     Select the built-in "Snapmaker PLA Full Spectrum" parameter package to use the color mixing feature and achieve better printing results.
     We recommend using a hot end of 0.4 mm or smaller, combined with a layer height of 0.1 mm or less. Using a larger hot end or higher layer height may result in visible layer lines on the final print.
     For guidance, refer to: Full Spectrum

Improvements

• 1. Optimized the color matching algorithm for filament synchronization.
• 1. Optimized viewport rendering performance by culling out-of-view geometry, so as to reduce unnecessary draw calls and improve overall responsiveness.

Bug Fixes

• 1. Fixed an issue in V2.3.5 where switching from the Prepare page to the Preview page automatically sliced all plates. It now slices only the plate currently selected in the Prepare page.
• 1. Fixed a bed temperature compatibility issue when using multiple filaments with different required bed temperatures. The system now defaults to the higher temperature.
• 1. Fixed an issue where Orca crashed when using the Full Bed Arrangement.
• 1. Fixed an issue where the Match mode ratio display was incorrect after switching tabs in the Color Mixing interface.
• 1. Fixed an issue where the interface loaded slowly when adding new filaments or machine configurations on Windows.
• 1. Fixed an issue on Windows where model files with special characters (e.g., extended Unicode characters or emojis) in Orca were imported as empty models or failed to load.
• 1. Fixed an issue where the software crashed during full-bed slicing on Windows/Linux due to excessive memory usage.
     A memory protection mechanism has been added to prompt you before proceeding with full-bed slicing.
• 1. Fixed an issue where Orca login became invalid after changing the password via the App under specific network conditions.
• 1. Fixed an issue where the software crashed when repeatedly importing the same G-code file.
• 1. Fixed an issue where slicing could proceed even when the filament flow ratio was set to 0. Slicing is now blocked and an error message is displayed.
• 1. Fixed an issue where double-clicking a G-code file (with Orca set as the default G-code viewer) caused the software to crash.
