No. User files are stored on a separate SPI flash partition. However, parameters (not files) are erased.
: Full compatibility with both Metric and Imperial units.
Format a USB drive (typically 4GB or smaller is recommended for compatibility) to .
: Verify your current version in the controller menu to ensure the new firmware is a higher version. ddcs v3 1 firmware update
A failed firmware update can brick your controller. Because the DDCS V3.1 lacks a dual-boot recovery system, a bad flash requires an expensive JTAG programmer to fix. Follow this checklist religiously.
Ensure files are in the root directory. Hold the key down before turning on the power. Try a different key if required by your specific vendor. Corrupted or incorrect firmware files.
Here is a step-by-step guide to updating your DDCS V3.1 firmware safely. Why Should You Update? : Full compatibility with both Metric and Imperial units
At its heart, the DDCS V3.1 uses an ARM9 main control chip paired with an FPGA co‑processor. This architecture delivers smooth motion and high processing speed. It can output up to , making it compatible with a wide range of stepper and servo drivers. The controller features a 4.3‑inch TFT display (480×272) and 17 dedicated keys for direct file selection, parameter adjustment, and machine control.
Better toolpath processing speeds, reducing jerkiness in complex G-code.
The standalone CNC controller market has a quiet workhorse: the . For years, it has offered a reliable, offline, MPG-equipped solution for milling, plasma, and router tables. But a recent firmware update has injected new life into this older platform. A failed firmware update can brick your controller
The DDCS V3.1 firmware update brings several exciting new features and improvements to the table. Some of the key enhancements include:
A controlled beta rolled out to volunteer fleets: municipal sensors, agricultural arrays, and research stations. Early adopters praised the improved uptime but surfaced surprising edge cases. One agricultural unit with an ancient power-management chip didn’t respect the new checkpoint write window and experienced flash wear spikes. A municipal sensor’s watchdog enforcement triggered unnecessarily on a busy reporting day.
: Power off the DDCS V3.1 controller. Insert the USB drive into the USB port on the back or side of the unit. Automatic Installation : Turn the power on. The controller will detect the
Release the button once the screen lights up and displays an update or installation progress bar.
