DDCS V3.1 Firmware Update: What’s New, Why It Matters, and Should You Upgrade?

The standalone CNC controller market has a quiet workhorse: the DDCS V3.1. 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. DDCS V3

If you own a DDCS V3.1, here’s everything you need to know about the latest firmware—and why ignoring it could be holding your machine back.

📥 How to Update Your DDCS V3.1

3. Improved Macro Support

For advanced users, Macros are the heart of automation. The V3.1 update introduces new macro commands and improves the execution speed of existing ones. This allows for more complex probing routines, tool length offsets, and automated homing sequences. If you have been limited by the logic capabilities of previous firmware, this update gives you much more breathing room.

2. Download the correct firmware

• Visit the manufacturer’s official website (e.g., richauto.com.cn or the reseller's support page).
• Search for: DDCS V3.1 firmware update file (usually a .bin, .hex, or .upd file).

5. UI and Menu Refinements

5. Bug Fixes

• Resolved a rare spindle PWM dropout when changing feedrate during a pause.
• Fixed MPG (manual pulse generator) jitter on low-resolution encoder wheels.
• Corrected incorrect DRO display after homing with soft limits enabled.

Software Requirements:

• The correct .bin file. Source this only from the board seller (like BuildBotics, Yuyong, or a verified CNC forum). Do not use random Google Drive links.
• DFU (Device Firmware Update) driver: STM32 bootloader driver (usually installed via Zadig or STM32 CubeProgrammer).

Error 3: Steppers Scream but Don't Move

• Cause: The new firmware reset the "Pulse Polarity" (active low vs high).
• Fix: In Motor Config, toggle "Pulse Edge" from "Rising" to "Falling."
