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.

Snapmaker 2.0 Firmware

Mar 4 2026: Snapmaker2_V1.21.0

Thank you for sharing your suggestions on how to improve the Snapmaker 2.0. We truly appreciate your feedback and support. Now, we’re excited to introduce the latest firmware update for the Snapmaker 2.0.

Changelog

Touchscreen

Added support for direct network connection between the machine and Snapmaker Orca. You can now send G-code to your machine over Wi-Fi without using Luban as a transfer station. Snapmaker Orca communicates directly with your machine through the OctoPrint protocol.

With the firmware you no longer need to launch Snapmaker Luban first to establish the connection. The only difference from before is the IP-address format, which now becomes: current device IP :8080 , e.g., 192.168.0.1:8080.

For step-by-step instructions, please click here to view the related Wiki article.

Added a Repeat Job button on the touchscreen. Once a 3D printing, laser, or CNC job is complete, you can repeat it with a single tap.

When preheating the heated bed or performing XY offset calibration using a single-head dual-nozzle, uploading and starting a print via Snapmaker Orca will interrupt the calibration process.

Uploading & starting a print from both Snapmaker Luban and Snapmaker Orca at the same time will cause the job to fail.

In some cases, when sending a file via Snapmaker Orca, the upload progress may remain at 0. If this happens, restart the machine and provide logs plus a description of the problem.

When using the rotary module, the “re-print” function may occasionally restart the job at a different origin.

When using the laser module for a reprint, pausing during the downward movement may result in a failure to return to the origin.
