Your work isn't entirely done once the update finishes. A few important steps will ensure smooth sailing:

Resolves known issues with G-code execution and coordinate saving.

The DDCS V3.1 firmware update enhances the stability and functionality of this standalone 3-4 axis CNC controller. Notably, as of early 2026, the DDCS V3.1 has been rebranded to for better internal identification, though the appearance and functions remain identical. Key Improvements in Firmware Updates

No more “SD card error” mid-job. The update improves FAT32 handling, increases maximum G-code file size to 4GB, and adds folder-based navigation.
