Second, UNO and module IO port correspondence description Stepper motor basic control needs of the pin, the other pin is in the engraving machine, or when the 3D printer used, here we do not make detailed, IO corresponds to the above figure. 8 ------------------------ EN (stepper motor drive enable side, active low) 7 ----------------------- Z.DIR (Z-axis direction control) 6 ----------------------- Y.DIR (direction control of the Y axis) 5 ----------------------- X.DIR (direction control of the X axis) 4 ---------------------- Z.STEP (Z-axis stepping control) 3 ---------------------- Y.STEP (Y-axis step control) 2 ---------------------- X.STEP (X-axis step control) // The following is a simple stepper motor control program, #define EN 8 // Stepping motor enable side, 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 stepping control #define Y_STP 3 // y axis step control #define Z_STP 4 // z axis step control / * // function: step function: control the direction of the stepper motor, the number of steps. // Parameters: dir direction control, dirPin corresponds to stepper motor DIR pin, stepperPin corresponds to stepper motor step pin, steps step number of steps // no return value * / Void step (boolean dir, byte dirPin, byte stepperPin, int steps) { DigitalWrite (dirPin, dir); Delay (50); For (int i = 0; i Condition: New, Country/Region of Manufacture: China, MPN: Does Not Apply, Brand: Unbranded/Generic
