Introduction
- The DDCS Expert is a 5 axis motion controller for open or close stepper and servo systems with 7 inch LCD full color display screen. The highest output pulse per axis is 1MHz.
- The users can self-define the functional keys. This controller supports multiple spindle mode, support straight Tool Magazine, gantry type Magazine, disk type magazine. The Operation system interface even though very comprehensive, can be learned in very short time.
- The DDCS Expert numerical control 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. Reliable control and easy operation.
- The internal operating system is Linux based.
- The DDCS Expert can be used for many styles and types of CNC machines. Lathes, Routers, Pick&Place and Mills, lathe and cutters are just a few examples. The DDCS Expert operates as a Stand Alone system without the need of a computer.

Stepper /Servo Driver Wiring
- The stepper / servo control output, the Pulse and Direction signal output voltage is ± 5V
- DDCSE Input and Output are the user-defined IO ports, In our example, we already set IN24 as the “ 5th axis servo alarm signal ” input port.
XP+: Pulse Signal Positive Output of the X Axis (5V)
XP-: Pulse Signal Negative Output of the X Axis (5V)
XD+: Direction Signal Positive Output of the X Axis (5V)
XD-: Direction Signal Negative Output of the X Axis (5V)
Limit, Home and Probe Inputs
- DDCSE Input and Output are the user-defined IO ports, In our example, we already set IN12, IN11 and IN10 as the “ axis limit signal ” Input port, and we already set the IN09 as “ Probe ” output port.
- Please note that the limit switch type should be NPN Normal Open, and the voltage range is 24VDC.
External Buttons
- DDCSE Input and Output are the user-defined IO ports, In our example, we already set IN23 as the “ External Start ” input port, IN22 as the “ External Pause ” input port, and IN21 as “ Extertnal Stop ” input Port.
- please choose the external buttons which is 24VD power supply input,then no need an external power supply for them.
Probe
- We already set the IN09 as “ Probe ” output port.
- Some users asked for the wiring methods for the probe with over-strock alarm,here we also set one sample for it.
- In the example, we go to the IO port to sent the IN07 as the “Probe signal”,IN06 as “Negative Z-axis hard limit signal”.
Needs two power supplies
- DDCS-Expert needs two power supplies,Main power is for controller system,IO Port power is for Input and Output and MPG ports. Both power supply is 24VDC,current is 3A.In the System Power input port ,the marked 24V and GND is the main power input ports;
- In the IO power input ports,the COM+ and COM- is the power input ports for Input/Output Port and MPG.Please keep in mind,only when the two power supplies are connected correctly the controller can be work properly.
- Many new users only give system power,then the limited switches,the relay,and MPG and spindle don’t work at all,then please go to check if you also give power to IO ports.IO power gives the power to all the IO ports,include the Limited switch,Relay,MPG,Etop and all other Input and output Ports,without it,spindle,MPG,Input and Output ports cannot work.
- In order to avoid electrical noise it is highly recommended to use two separate 24V power supplies.
- It is highly recommended to intall a noise filter.
Support MPG
- All the input signal COMMON termimal is COM-, not GND; Never short connect GND and COM-;
- The MPG need the power from IO power port ( COM+ / COM- ), or the MPG cannot work;
- Because of the limit of the pins, if X10 and X100 is not selected, the system just select X1 by default.
- With the MPG, and press the “Try Cut” key, the system can change to “Handwheel guiding” mode.
- Please Turn the Handwheel to counterclockwise direction, the Try Cut (Handwheel guiding) can be active.
- In order to make the convenient for the users, we already solder the MPG cables to the PIN15 male interface plug.
Relay Wiring
- By Configuration of more Spindle Output ports, the spindle control output terminal offers connections for Start / Stop of Cooling ( M8 / M9 ) and Start / Stop of Lubrication ( M10 / M11 ) and so on.
- For example, it can be used for a Relay output port. Following figure shows the wiring methods.
If Relay Power Supply is 24VDC:
- DDCS Expert Input and Output are the user-defined IO ports,as our example here,we already set OUT10 as the “Cooling on/off” output port,and we already set the OUT01 as Vacuum valve on/off” output port.
If Relay Power Supply is not 24VDC:
- The users need to use an external power supply,then we will provide the Schemat-ics drawing.
The Wiring for the Multi-Speed Spindle
- FOR:Spindle Start/Stop-Forw ard Rotation and Stop Output of spindle(OUT21)
- COM-: Spindle Output COMMON(Cannot short connect with ACM)
- VSO: Analog Output
- ACM: Analog Ground
- (Connect with Anaog input port of the inverter)
- There are 3 parameters related to the Multi-speed spindle:
- #079-“Spindle interface type”;Here we need to set it to “ Multi-speed ”
- #088 -- “Multi-speed section counts”; The section count value range is 2-8, the users can set 2-8 different spindle speed.
- #082 -- “Max.Spindle Speed”.
- The the wiring for the Multi-Speed Spindle as above wiring.
Spindle Wiring
- In the Param Page, by #079, we can define the spindle mode.
- In Analog Spindle, the speed controlling output terminal can output 0-10V. It can adjust the speed of the spindle by sending the voltage between 0 and 10V to the VFD according the the Spindle Speed Setting.
- Controlling the speed of a spindle with a VFD only needs the Start/Stop signal and the 0-10V signal to control the frequency.
- FOR port is same wiring methods as the normal Output Ports.
- FOR is for spindle forward rotation output or start/stop output;
- Analog circuit is isolated with Power supply output,Never short connect the ACM and COM- ( DCM );
- If only need the Start and Stop command for the spindle, then just connect FOR output port of the controller with Start input port of the VFD.
- The "VSO" and "PWM" only one port is avaiable for one configuration. Use "VSO" port or "PWM" port, the two ports cannot be used at the same time.
Functional/Performance comparison between DDCS-Expert and DDCSV3.1
When operating the DDCS, the users will come across some English abbreviations. Here a list with explanations:
- FRO: Feed Rate Override
- SRO: Spindle Rate Override
- SJR: Jog Speed Setting
- F: Feed rate, unit is mm/min
- S: Spindle Speed, unit rev/min.
- X: The coordinate code of the X axis.
- Z: The coordinate code of the Z axis.
- A: The coordinate code of the A axis
- BUSY: The system is busy. You still can adjust FRO and SRO
- READY: READY mode, any operation can be done
- RESET: Reset mode, controller is in “OFF” mode, no operation can be performed
- CONT: Continuous mode, each axis can be manually jogged with the arrow keys
- Step :Manual Step Mode，each axis can be jogged in defined steps
- MPG: MPG mode. Operate the machine with the MPG (Manual Pulse Generator)
- BUSY: Run G code. Auto is showing when file is processing

Nice controller. Still working on getting everything dialed in. It didn’t come with much instruction, but the manual is available (2 parts) online. I got this during a Prime day, so the price was pretty good at that time. Watch for sales.I’m using it for a plasma cutter, but I’ve built it so I can use it with various equipment. (We shall see how that plays out?)Best of luck to you!I’ll take and post some shots and vids to follow up with this.

Had a few issues but they respond well and overnight when you ask them a question. Be aware that this unit requires you to hook up both positive and negative terminals for all wires instead of having a common cathode or anode. A bit of a pain but I made it work. Has some nice software compared to my previous model.

This controller is a great value. This is a great choice for someone building their own CNC. Documentation is available from the manufacturers website. Most of the important stuff to look at is in the install folder. Slib-g and slib-m have all the macros. Eng file has a full list of all parameters. The comments are in Chinese, but they can be translated. It is possible to write user macros. There are some functions that do not work(G41,G42,G43). So far I am very impressed. Be sure to update it as well, there have been several updates since I got mine

The controller was well built, the UI is nice, but as of 10/2/2021 the unit does NOT support slaving an axis (X, Y, Z) to the 4th axis to allow for a dual motor driven axis. If your unit uses a single motor per axis on each of X, Y, and Z then you will be good to go, but if your machine is one of the larger machines that requires dual motors on any axis ( commonly X or Y ) then this unit will not work.
