There are two primary methods: (easiest) and DFU Mode (for recovery). We will cover the standard USB method first.
For safety, update the firmware while the CNC machine components are idle or disconnected from the relay triggers.
Wait until the screen displays a success message or automatically reboots to the main interface. This usually takes 1 to 3 minutes. Remove the USB drive after the main menu loads. Post-Update Verification and Calibration ddcs v3 1 firmware update

The DDCS V3.1 is a highly reliable 3-axis or 4-axis standalone motion controller widely used in the hobbyist and professional CNC community. Operating without the need for a dedicated computer, its performance and stability rely heavily on its internal software. Keeping your controller updated ensures you have access to the latest bug fixes, safety protocols, and feature enhancements.
The V3.1 update refines these algorithms. Arc interpolation allows a user to mill a circular pocket or boss using a simple X/Y coordination setup without needing a CNC system. The firmware calculates the incremental steps required to keep the tool path circular. Updates in V3.1 have smoothed these movements, reducing the "stepping" effect sometimes seen in older firmware where the movement looked jagged. This results in a better surface finish on the workpiece and less wear on the mechanical components of the milling machine due to smoother acceleration and deceleration profiles.
