In the late development of multi-axis nc engraving machine system

MCU is S3C44B0X chip, but the CNC engraving machine control system for stepping motor has enough to do its work, rather than with FPGA is the EP1C6T144 Cyclone series, using Verilog programming, common to the logic unit 5839, in addition to complete the basic function, also completed the x, y, z three axis in the process of carving the absolute coordinates of real-time display, x, y, z motor pulse is adjustable and triaxial pulse equivalent inconsistent deformation of sculpture, data protection, electricity seamless continuation, automatic knife, hand control condition of single step, micro step and continuous movement and a series of functions. Due to the present stage on the functionality and performance fully meet customer requirements, combined with development time is tight, so has not yet to further optimize the FPGA program, believe that after the optimization in does not affect the performance of the premise, can greatly reduce the usage of the logical unit.
