The DDCS V4.1 Digital Dream Offline CNC Controller is the latest version of the popular DDCS V3.1, featuring major performance and usability upgrades. This standalone motion controller, available in 3-axis or 4-axis versions, operates completely offline — no PC connection required — and delivers high-speed, precise, and stable motion control for CNC routers, engravers, milling machines, and automation systems.
Please note: The controller requires two 24V DC power supplies (minimum 0.5A each) for proper operation.
Upgrades from the DDCS V3.1:
-
Larger 7" TFT display with 1024 × 600 resolution for improved visibility and clarity
-
Second USB port and added Ethernet port for enhanced connectivity
-
Axis slaving function for X, Y, or Z axes (ideal for dual-motor setups)
-
Added servo spindle control option
-
New programming features: Polar coordinate commands, rotation commands, and full radius compensation
-
Improved motion algorithm for smoother performance with long G-code programs containing short segments
-
Fast resume function — quickly start from a specified line or nearest point, regardless of file size
-
Enhanced simulation mode — adjust feed rate override (FRO), verify tool paths, and test soft limits; supports pause and resume
-
Individual driver alarm input ports for closed-loop motor systems
-
Added cycle encoder for A-axis (4-axis version only) allowing unlimited rotation
-
New analysis prompt window for diagnostic feedback
-
More E-stop parameters for greater safety and control
-
32-bit speed generator offering higher resolution for speed and acceleration, improving positioning accuracy
