1 DDCS-Expert Brief Introduction

1.1 Product Brief Introduction

Thank you for your interest in our standalone motion controller and for taking the time to

read this manual.

Digital Dream is a numerical control company specializing in the research, development

and production of various CNC (Computer Numerical Control) systems since 2008. Digital Dream
aims to combine high quality and high reliability with aﬀordability.

The DDCS Expert is a 3~5 axes motion controller for open or close stepper and servo systems

with 7/10.2 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. This guarantees 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. This guarantees high precision, accuracy
and reliability.
