3D CNC Shield V3 Printer Expansion Board Tato expanzní deska je vhodná pro rycí stroje, 3D tiskárny, apod. Obsahuje 4 sloty pro A4988 drivery krokových motorů.     Obsah balení: 1 x 3D Arduino Shield pro 3D Tiskárny Příklad:   //The following 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 direction of the stepper motor , the number of steps. / / Parameters : dir direction control , dirPin corresponding stepper motor DIR pin , stepperPin corresponding stepper motor " step " pin , Step number of step of no return value. * / void step (boolean dir, byte dirPin, byte stepperPin, int steps) { digitalWrite (dirPin, dir); delay (50); for (int i = 0; i digitalWrite (stepperPin, HIGH); delayMicroseconds (800); digitalWrite (stepperPin, LOW); delayMicroseconds (800); } } void setup () {/ / The stepper motor used in the IO pin is set to output pinMode (X_DIR, OUTPUT); pinMode (X_STP, OUTPUT); pinMode (Y_DIR, OUTPUT); pinMode (Y_STP, OUTPUT); pinMode (Z_DIR, OUTPUT); pinMode (Z_STP, OUTPUT); pinMode (EN, OUTPUT); digitalWrite (EN, LOW); } void loop () { step (false, X_DIR, X_STP, 200); / / X axis motor reverse 1 ring, the 200 step is a circle. step (false, Y_DIR, Y_STP, 200); / / y axis motor reverse 1 ring, the 200 step is a circle. step (false, Z_DIR, Z_STP, 200); / / z axis motor reverse 1 ring, the 200 step is a circle. delay (1000); step (true, X_DIR, X_STP, 200); / / X axis motor forward 1 laps, the 200 step is a circle. step (true, Y_DIR, Y_STP, 200); / / y axis motor forward 1 laps, the 200 step is a circle. step (true, Z_DIR, Z_STP, 200); / / z axis motor forward 1 laps, the 200 step is a circle. delay (1000); } Note: When inserting the A4988 module, must be careful not to insert opposite. Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.   UNO for Arduino---------------------- expansion board 8 ------------------------ EN ( stepper motor driver enable , active low ) 7 ----------------------- Z.
