Incremental Counter

I changed the code in function of the example of StateChangeDetection:

#include "AccelStepper.h"

AccelStepper stepper (1, 9 , 8);

#define home_switch 4
#define buttonState 7
long initial_homing = -1;
int x;
int sensorPushCounter = 0;
int sensorState = 0;
int lastsensorState = 0;


void setup() {


   
   pinMode(home_switch, INPUT_PULLUP);
   
   delay(150);  

  stepper.setCurrentPosition(0); 
  stepper.setMaxSpeed(1.0);      
  stepper.setAcceleration(1500.0); 
  initial_homing=1;
  
  while (digitalRead(home_switch)) {    
    stepper.moveTo(initial_homing);  
    initial_homing++;  
    stepper.run(); 
    delay(5);
}


  stepper.setCurrentPosition(0); 
  stepper.setMaxSpeed(1.0);      
  stepper.setAcceleration(1500.0); 
  initial_homing=1;

  while (!digitalRead(home_switch)) { 
    stepper.moveTo(initial_homing);  
    stepper.run();
    initial_homing++;
    delay(5);
  }
  
  stepper.setCurrentPosition(0);
  x == 0;
  stepper.setMaxSpeed(30.0);      
  stepper.setAcceleration(40.0);
  stepper.setSpeed(20);  

}
 
void loop()
{       
  sensorState = digitalRead(buttonState);

  if (sensorState != lastsensorState){
    if (buttonState == HIGH){
      sensorPushCounter++;
    }
  }


  if (sensorPushCounter % 9 == 0) {
    stepper.runSpeed();
  } else {
    stepper.stop();
  }


  if (digitalRead(home_switch) == HIGH) {
    stepper.stop();
    sensorPushCounter = 0;
    }
}

Now the stepper runs like crazy without stopping. It doesn't respond to the sensor or to the home_switch.

Any idea of why??
