Snapmaker Orca Updates & Release Notes

Download Link

Download V2.3.5

New Features

1. Added Top Cover controls.
2. Added a filament sync feature. You can sync filament information from the printer to Orca using Match Mapping or Direct Override.
3. Added an official filament color library panel with support for dual-color official filaments.
4. Added a warning when Variable Layer Height and Subdivide Mix Layer are enabled simultaneously.
5. In Color Mixing mode, if an incompatible filament combination is used, slicing is blocked and an error is displayed.
6. Added support for Snapmaker PVA and optimized the print profiles for Snapmaker PLA-CF and Snapmaker TPU.

Improvements

1. Optimized the wipe tower structure by adding an opening in the outer wall.
2. Optimized the Snapmaker Orca startup animation.

Bug Fixes

1. Fixed an issue where filament types were displayed incorrectly after reopening a saved project. This issue occurred when the project contained multiple filament types and the number of filaments was reduced in Orca after the project was saved.
2. Fixed an issue where 25% mixing recommendations were still displayed after the minimum mixing ratio for Match mode was set to 30%.
3. Fixed an issue where layer height subdivision was incorrectly applied to single-color regions. This occurred when Full Domain was enabled and both single-color and color mixing painting used the same layer height.
4. Fixed an issue that caused incorrect filament usage estimates for the wipe tower.
5. Fixed an issue where the wipe tower brim overlapped with the model brim.
6. Fixed an issue where web resources and process resources could not be used properly after a hot update.
7. The Independent Support Layer Height option is now available without disabling the wipe tower. It is unchecked by default.
8. Fixed an issue where Snapmaker Orca could become unresponsive after startup on some PCs.

Bug Fixes

• Fixed an issue where filament mapping failed on the Print Preprocessing page when Generic Support for PLA was selected.
• Fixed an issue where slicing painted models with dome-shaped structures could result in maze-like patterns, island artifacts, or partial geometry loss.
• Re-enabled infill parameter settings under Process > Multimaterial > Filament for Features.
• Fixed an issue with the Fuzzy Skin painting feature where certain painted areas failed to generate Fuzzy Skin while unpainted areas incorrectly generated it.
• Fixed an issue where sparse infill patterns were misaligned on the first layer.

New Features

1. Introduced Full Spectrum (Beta) printing.

(1) Color Mixing

Ratio: Supports mixing of two or three filament colors.

Cycle: Supports mixing by entering filament color codes.

Match: Supports matching mix effect to a target color.

Gradient: Supports creating a gradient effect by mixing two filament colors.

(2) Subdivide Mixing Layers

Subdivide mixing layers: When enabled, layer height for mixing areas will be subdivided for better color mixing results.

Full domain: When enabled, subdivided layer height applies to all mixed-color regions on outer walls, whether the colors are created by painting or filaments changes.

Apply subdivision to infill: When enabled, infill within mixed-color regions is subdivided using the same settings.

1. Added support for new filament types for the Snapmaker U1.

Improvements

1. Optimized the rib structure of the prime tower. A quadratic programming approach is used to constrain the rib area to a square shape, enhancing the stability of the prime tower during printing.

2. Optimized printing from local files. The system can now correctly configure the filament-to-nozzle mapping even when the filament density is 0, preventing printing anomalies.

Bug Fixes

1. Fixed an issue where the first layer of the prime tower could exceed limits under certain process parameter configurations.

2. Fixed a series of issues that could occur when a 3MF file contained more filaments than available extruders:

• Excess filaments could not be saved.
• Slicing could fail.
• Filament mapping between the software and the printer could be incorrect on the Print Preprocessing page.

1. Fixed an issue where Upload and Upload and Print were unavailable when port 13619 was occupied by another process.

2. Fixed an issue where filament mapping could fail when starting a print directly from the built-in model library.

This version is a hotfix update based on V2.3.1.

Bug Fixes

Fixed an issue on the Print Preprocessing page: when more than 4 preset filaments were available, users could not select the excess filaments to match with the mounted filaments on the device.

How to Update

1. Restart the software
   Restart Snapmaker Orca.

2. Automatic update detection
   If the Configuration update dialog appears, click OK. After the configuration package is installed, restart the software to complete the update.

3. Manual update check
   If the update prompt does not appear automatically after restarting, go to the top navigation bar and click Help > Check for Web Resource Updates. In the Configuration update dialog, click OK. After the configuration package is installed, restart the software to complete the update.

• Fixed an issue where some U1 printers failed to retrieve filament information after connecting.

Improvements

• Optimized the camera countdown feature: removed the countdown in Cloud Mode, and cancelled the 5-minute limit in LAN Mode.

New Features

• Added a Model Library section, allowing you to download 3MF or G-code files and start print jobs directly online.

Some model creators have only authorized the sharing of G-code files, so 3MF files are not available.

• Added new official material types.
• Added color options for third-party materials.

Bug Fixes

• Fixed an issue where the software crashed when printing with filaments that use a transparent channel.
• Fixed occasional lag in certain HTTP requests.
• Fixed abnormal page redirection when switching, adding, or removing printer models.
• Fixed an issue where U1 disconnected in LAN mode.

Improvements

• Corrected the name of Polymaker filaments.

New Features

• Snapmaker Orca now supports independent updates for Mainland China and other regions.
• Introduced hot update support for Snapmaker Orca process presets.
• Introduced hot update support for Snapmaker Orca web resources.
• Added the chamfer feature for the prime tower brim to enhance the stability of the Rib prime tower.
• Introduced new material types, including Snapmaker PETG HF, Snapmaker TPU 95A HF, Generic PETG HF, and Generic TPU 95A HF. Snapmaker PETG HF and Snapmaker TPU 95A HF will be available in the official online store in a future update.

Bug Fixes

• Fixed an issue where Snapmaker Orca could not be launched in certain Windows 11 environments.
• Fixed an issue where the process migration feature failed when switching between machine models.
• Fixed an issue where extrusion lines or travel paths were generated outside the build plate when using a Rib wipe tower.
• Fixed filament synchronization issues that could occur when connecting to the device. For example, in cases where filaments were not installed from the filament library, the new version resolves:
  • An issue where Snapmaker PLA Snapspeed density being 0 could prevent print jobs from being sent;
  • An issue where Generic PETG with a first-layer PEI steel sheet bed temperature set to 0 could cause poor first-layer print quality.
• Fixed an issue that caused the software to crash in certain scenarios.
• Fixed an issue where Bambu Lab printer models could not be selected on the Prepare page.
• Fixed Italian translation inaccuracies on Windows.
• Fixed an issue where the IP address reported by the device to Snapmaker Orca is inconsistent with its actual IP address, causing problems such as being unable to retrieve material information or unable to print on the Print Preprocessing page.
• Fixed an issue where users had to log in frequently.

Improvements

• Improved the warning for spiral lifting near the build plate boundaries.
• Optimized the popup scenario when switching between multiple pages.
• Improved the monitoring retrieval efficiency and file upload efficiency when the computer and device are on the same local network.

This version is a non-official release. It primarily addresses issues where the Rib wipe tower caused extrusion or travel paths to extend beyond the build plate, as well as an issue where Bambu Lab printer models could not be selected. In addition, the software update mechanism has been optimized. If you have encountered any of the issues above, we recommend upgrading to this version to improve your experience. The official release is scheduled for mid-February. Stay tuned!
