Here’s a feature-style article about the DDCS V3.1 firmware update, written for CNC hobbyists and professionals using the standalone offline controller.
One of the most practical quality-of-life improvements in V3.1 is the enhanced USB (U Disk) support. Previously, users often faced issues with certain USB drive formats or naming conventions. The V3.1 update improves the recognition of file names and directories, making file transfers from your design computer to the CNC controller seamless.
A common complaint in previous iterations was a slight "lag" in the MPG (Manual Pulse Generator) or electronic handwheel. V3.1 optimizes the interrupt timing, resulting in smoother jogging and a more direct "feel" when positioning the spindle manually. This is critical for precision work like PCB engraving or inlay work.
Warning: Do NOT install a DDCS V3.1 firmware update intended for the "DDCS V3.1 Plus" or "DDCS Expert." While physically similar, the bootloaders are different. Always check your PCB revision (look for the silkscreen near the SD card slot).
