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

New Features

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.

Known issues

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.
