2 Stepper motors with drivers - Help

My aim is to have two steppers, one for the x - axis and one for the y - axis. Will this code work, or am i missing somthing?

#include <Stepper.h>

const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution
                                     // for your motor
                                     

// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 4,5,6,7,8,9,10,11);  

void setup() {
  // initialize the serial port:
  Serial.begin(9600);

const unsigned long int X_STEPS_MAX = 745683;
const unsigned long int Y_STEPS_MAX = 87346;

unsigned long int X_position = 0;
unsigned long int Y_position = 0;

boolean X_increasing = true;

void loop() {
    if (X_increasing) {
        if (X_position == X_STEPS_MAX) {
             Y_position ++;
             Y_step_down();
             X_increasing = false;
         } else {
            X_position++;
            X_step_right();
         }
    } else { // decreasing
        if (X_position == 0) {
             Y_position ++;
             Y_step_down();
             X_increasing = true;
         } else {
            X_position--;
            X_step_left();
         }
     }

   while (Y_position == Y_STEPS_MAX);  // stop everything
}

Jackdowniels:

// initialize the stepper library on pins 8 through 11:

Stepper myStepper(stepsPerRevolution, 4,5,6,7,8,9,10,11);

You've left out quite a bit of detail, but this is no good for starters. You probably want:

Stepper myStepperX = Stepper(stepsPerRevolution,4,5,6,7);  
Stepper myStepperY = Stepper(stepsPerRevolution,8,9,10,11);

Alright, thank you very much :slight_smile:

this is very simple code i put together for roughly the same thing, im not sure what motors/driver combo your using but this works very well for me. youll more than likely need to change the variables bc i have fine tuned them for my system. good luck!!

#include <Stepper.h>

const int stepsPerRevolution = 64;

Stepper pan(stepsPerRevolution, 8,10,9,11);
Stepper tilt(stepsPerRevolution, 3,5,4,6);

void setup() {

pan.setSpeed(300); // pan
tilt.setSpeed(300); // tilt
}

void loop() {

int sensorReading = analogRead(A0); // pan

if (sensorReading < 300) { pan.step(4); } // pan left
if (sensorReading > 800) { pan.step(-4); } // pan right

int sensorReading2 = analogRead(A1); // tilt

if (sensorReading2 < 300) { tilt.step(4); } // motion down
if (sensorReading2 > 800) { tilt.step(-4); } // motion up

}
