CNC Shield V3 using A

Projects Programming
1

I'm using a CNC Shield V3, and I have a Stepper motor hooked up to X and its working just fine.
I wanted to use A for another stepper motor. Per their website it says to use pins 12 13, however for some reason the motor does not spin or make noise like its trying to.

CNC Shield doc Arduino Compatible CNC Shield Instructions

I used the same code i had for X and just switched the pins, but I get nothing, any ideas?
My code is below.

#define d_xDir 12
#define d_xStep 13

#define enable 8

//Total Steps to move
int stepDelay_swing = 60; //Delay between each pause

void setup() {
 
 pinMode(d_xDir, OUTPUT);
 pinMode(d_xStep,OUTPUT);
 
 pinMode(enable,OUTPUT);
 digitalWrite(enable, LOW);
}

void step_swing(boolean dir, byte dirPin, byte stepperPin, int steps)
{
  
  digitalWrite(dirPin, dir);
  for(int i = 0; i < steps; i++){
    digitalWrite(stepperPin, HIGH);
    delayMicroseconds(stepDelay_swing);
    digitalWrite(stepperPin, LOW);
    delayMicroseconds(stepDelay_swing);
  }
}


void loop() {
  
        step_swing(true,d_xDir,d_xStep,2000);
        delayMicroseconds(stepDelay_swing);
        step_swing(false,d_xDir,d_xStep,2000);

        delay(2000);
}

Did you put two jumpers in the box on the left to connect A.STP and A.DIR to D12 and D13?

Yes, see image.
As you can see in the image I have the same stepper motor hooked up to X and it works perfect.

anyone?

From the picture it appears you have EIGHT jumpers where only TWO should be used. The block where you have the two black jumpers, the three blue jumpers, and the three yellow jumpers should only have the two black jumpers, connecting A.STP and A.DIR to D12 and D13. The blue jumpers are shorting A.STP to X.STP, Y.STP, and Z.STP. The yellow jumpers are shorting A.DIR to X.DIR, Y.DIR, and Z.DIR.

Are you sure you have the driver boards plugged right-way around? The two styles of driver (A4988 and DRV8825) have the current limit trim pot on opposite ends.

There are only 2 on the bottom ones.

I actually figured it out, inhad the dir and step pins backwards.

Oops. I thought the blue and yellow things were jumpers, not pins. My mistake.
Glad you got it figured out.
