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———————– Z.DIR (Z-axis direction control)

6———————– Y.DIR (Y-axis direction control)

5———————– X.DIR (X-axis direction control)

4 ———————- Z.STEP (Z-axis stepper control)

3 ———————- Y.STEP (Y-axis stepper control)

2 ———————- X.STEP (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

// Function: step function: to control the stepper motor direction, the number of steps.

// Parameters: dir direction control, dirPin DIR pin corresponding to the stepper motor, stepperPin step pin corresponding to the stepper motor, stepping a few steps steps
