DDCS-EXPERT CNC Offline Controller

The DDCS Expert Standalone Motion Controller is a device that is used to control the movement of machine tools such as CNC (Computer Numerical Control) lathes, milling machines, and other equipment. It is a standalone controller, which means that it can operate independently without the need for a separate computer or other devices to provide input or receive output. The DDCS Expert Motion Controller supports 3, 4, or 5 axes of motion and can be connected to the machine via USB. It is designed to work with a variety of software programs, including CNC machine control software, and is capable of executing a wide range of motion control tasks. The DDCS Expert Motion Controller is commonly used in manufacturing, robotics, and other industries that require precise and precise control of machine movement.

Updated 3/4/5 Axis Cnc Offline Controller Ddcs-expert Supports Tool Magazine/atc Stepping Drive Instead Of Ddcsv3.1


The DDCS Expert is a 3~5 axis CNC motion controller for open or close stepper and servo systems with a 7/10.2 full-color display screen. The highest output pulse per axis is 1MHz. The users can self-define the functional keys. This CNC controller supports multiple spindle modes, support straight Tool Magazine, gantry type Magazine, and disk type magazine. The Operation system interface, although very comprehensive, can be learned quickly.
The DDCS Expert CNC controller mach3 system adopts the ARM+FPGA design framework. ARM controls the human-computer interface and code analysis and the FPGA provides the underlying algorithms and creates the control pulse. This guarantees reliable control and easy operation. The internal operating system is Linux based.

Manual and Software

The version 2022-02-08 software added one very important feature for DDCS-Expert, the users can configurate the slave axis, that is very useful for Doube-Y structure CNC machine.Here is the related parameters:
#488 -p1 -a3 -t2 -s1"Programming axis of physical axis 1" -m1 -min=0.000 -max=4.000 -i0"X" -i1"Y" -i2"Z" -i3"4th" -i4"5th"-s3" "
#489 -p1 -a3 -t2 -s1"Programming axis of physical axis 2" -m1 -min=0.000 -max=4.000 -i0"X" -i1"Y" -i2"Z" -i3"4th" -i4"5th"-s3" "
#490 -p1 -a3 -t2 -s1"Programming axis of physical axis 3" -m1 -min=0.000 -max=4.000 -i0"X" -i1"Y" -i2"Z" -i3"4th" -i4"5th"-s3" "
#491 -p1 -a4 -t2 -s1"Programming axis of physical axis 4" -m1 -min=0.000 -max=4.000 -i0"X" -i1"Y" -i2"Z" -i3"4th" -i4"5th"-s3" "
#492 -p1 -a5 -t2 -s1"Programming axis of physical axis 5" -m1 -min=0.000 -max=4.000 -i0"X" -i1"Y" -i2"Z" -i3"4th" -i4"5th"-s3" "
For example, If you want configurate the 4th. Axis as the slave axis for Y axis, set the #491 to "1".
