New cnc shield v3 engraving machine / 3D Printer / A4988 driver expansion board for Arduino Free shipping
 
II UNOAnd moduleIOCorrespondence between the introduction port
 
 
The basic needs of the stepper motor control other pins are in the engraving machine, or3DWhen the printer was used, here we do not make Detailed,IOIt corresponds to the above figure
Expansion board UNO ----------------------
8 ------------------------ EN (stepper motor drive enable, active low)
7----------------------- ZDIR (Z-axis direction control)
6----------------------- YDIR (Y-axis direction control)
5----------------------- XDIR (X-axis direction control)
4 ---------------------- ZSTEP (Z-axis stepper control)
3 ---------------------- YSTEP (Y-axis stepper control)
2 ---------------------- XSTEP (X-axis stepper control)
// Here is a simple stepper motor control procedures,
#define EN 8 // stepper motor enable, active low
#define X_DIR 5 // X axis stepper motor direction control
#define Y_DIR 6 // y-axis stepper motor direction control
#define Z_DIR 7 // z-axis stepper motor direction control
#define X_STP 2 // x-axis stepper control
#define Y_STP 3 // y-axis stepper control
#define Z_STP 4 // z-axis stepper control
