Arduino coding on MKS Gen L board with DRV8825

Hi, I'm sorry with my poor english :frowning:

I wanna ask something, I making 6axis robot arm with MKS Gen L V1.0(Atmega2560 chip) board.

I used marlin, repetier(driver, motor work well.), but I want to code directly on Arduino code.

With DRV8825 stepper driver, I used

const int dirPin = 55;
const int stepPin = 54;
const int stepsPerRevolution = 200;
 
void setup()
{
  // Declare pins as Outputs
  pinMode(stepPin, OUTPUT);
  pinMode(dirPin, OUTPUT);
}
void loop()
{
  // Set motor direction clockwise
  digitalWrite(dirPin, HIGH);
 
  // Spin motor slowly
  for(int x = 0; x < stepsPerRevolution; x++)
  {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(2000);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(2000);
  }
  delay(1000); // Wait a second
  
  // Set motor direction counterclockwise
  digitalWrite(dirPin, LOW);
 
  // Spin motor quickly
  for(int x = 0; x < stepsPerRevolution; x++)
  {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(1000);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(1000);
  }
  delay(1000); // Wait a second
}

but it doesn't work. I set pin number correctly, I check power on board 24V.

I think main problem is that after enter DRV8825, no current to stepper motor.

I check EN/STEP/DIR/GND pins with multimeter, its okay!
But when I check 4 pins that after driver, it has no current.

So, maybe there are problem with Driver code or pins.

Are there any setting with CS_PIN or ENABLE_PIN ?
At above code, it has only dir/step pin with no enable pin.

I'm missing something with MKS board setting.. ㅠㅠ help me
