Test Stepper Motor [Beginner]

Projects General Guidance
1

Hello !

I launched into the programming for a week for a project in connection with my studies. However my beginner's level returns complicated things.
I have to realize a program to test two engines step by step(Which moves a rail in translation), here is my specifications :

" Realize the program which will later allow to verify the smooth running of the engines of axes X and Y.
1st Program:

  • a procedure of grip of origin (By means of the sensors of the end of running)
  • a sequence of movement such as described below:
    Travel of 100mm according to X.
    Travel of 50mm according to Y.
    Travel of - 50mm according to X.
    Travel of 70mm according to Y.
    Return in the point of origin. "

Here is the material which I have at my disposal:
-L298N Hour-bridge.
-2 moters step by step

  • a card Arduino
  • 4 Sensors of the end of running

I used the function steppers to realize a program but I meet many problems at the level of the programming :

#include <Stepper.h>
const int stepsPerRevolution = 200;
// initialize the stepper library on pins 2-5 n 8-11
Stepper myStepper1(step_360,2,3,4,5);
Stepper myStepper2(step_360,8,9,10,11);
void setup()
{
// set the speed at 60 rpm:
myStepper1.setSpeed(60);//left
myStepper2.setSpeed(60);//right
// initialize the serial port:
Serial.begin(9600);
} myStepper.setSpeed(60);

void loop() {
stepper1.move(200);
stepper2.move(200);
do {
stepper1.run(); // Update du moteur 1
stepper2.run(); //Update du moteur2
capteur = digitalRead(8);
capteur = digitalRead(10);
} while (capteur == LOW);
stepper.stop();
stepper.move(-500);
do {
stepper1.run(); // Update du moteur 1
stepper2.run(); // Update du moteur 2
} while ( stepper1.distanceToGo() != 0 ) || ( stepper2.distanceToGo() != 0);
delay(50);
}
{
Moteur1.step(?); //I have to calculate the report between the steps of the engine and the distance traveled by the wagon.//
delay(50);
Moteur2.step( ?);
delay(50);
Moteur1.step( ?) ;
delay(50);
Moteur2.step( ?) ;
delay(50);
}
{
stepper1.move(200);
stepper2.move(200);
do {
stepper1.run();
stepper2.run();
capteur = digitalRead(8);
capteur = digitalRead(10);
} while (capteur == LOW);
stepper.stop();
stepper.move(-500);
do {
stepper1.run(); // Update du moteur 1
stepper2.run(); // Update du moteur 2
} while ( stepper1.distanceToGo() != 0 ) && ( stepper2.distanceToGo() != 0);
delay(50);
}

Thanks ! :wink:

You need to post your code between code tags, not quote tags. Code tags can be generated using the </> button in the "Post" or "Reply" window.

There are so many problems that it's hard to know where to start.
In this section:-

void setup()
{
    // set the speed at 60 rpm:
    myStepper1.setSpeed(60);//left
    myStepper2.setSpeed(60);//right
    // initialize the serial port:
    Serial.begin(9600);
}  myStepper.setSpeed(60);

you need to delete this:-

myStepper.setSpeed(60);

because
a. You can't have that statement outside the function
b. You don't have a stepper called "myStepper"

Next, you have these lines at the beginning of 'loop()':-

  stepper1.move(200);
    stepper2.move(200);

but you don't have steppers called "stepper1" and "stepper2".

Then, in your 'do..while' loop, you have:-

capteur = digitalRead(8);
capteur = digitalRead(10);

You can't use the same variable to do both digital reads. The second overwrites the first, so you're only effectively reading pin 10.
And you never declare a variable called "capteur" anyway.

Next, you do this:-

  stepper.stop();
    stepper.move(-500);
    do
    {
        stepper1.run();                         // Update du moteur 1
        stepper2.run();                         // Update du moteur 2

when you've never declared steppers named "stepper", "stepper1" or "stepper2".

Then you do:-

  Moteur1.step( ? ); //I have to calculate the report between the steps of the engine and the distance traveled by the wagon.//
    delay(50);
    Moteur2.step( ? );
    delay(50);
    Moteur1.step( ? ) ;
    delay(50);
    Moteur2.step( ? ) ;

but again, you've never declared a stepper called "Moteur1" or "Moteur2". And these will do nothing : ? . (Real values might be a good idea.

Heaps more of the same types of errors all through, and a few others.

You need to stop, go and learn a bit about programming, study the "Stepper" library commands, then start again from the beginning. To be frank, it hurts just looking at this code.
