Computer engraving machine for the knife device circuit design

Computer engraving machine long for knife device using multiple independent single chip microcomputer control system, complete the function of the four main areas:
( 1) Waiting for the computer engraving machine CNC system issued instructions for the knife, accept the instructions to the knife after action against the knife. Action against the knife after the completion of the feedback signal to the numerical control system to the edge of the sword;
　　( 2) Computer engraving machine CNC system at any time may terminate the status on the edge of the sword;
　　( 3) No knife when receiving computer engraving machine CNC system Z axis pulse instruction, then the pulse commands sent to the single-chip microcomputer system control of the motor. To realize the distribution of Z pulse;
　　( 4) Dial the code switch decided whether this motor according to the panel. The circuit diagram is shown in figure 1. Figure 1
