DDCS V3.1 3-4 Axis 500Khz CNC Standalone Motion Controller

DDCSV3.1 offline cnc controller  

The DDCS V3.1 is updated from DDCSV2.1,which fix the bugs on software and hardare.DDCS V3.1 is a 4 axis motion controller for stepper and servo systems,the 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.
