Arduino Mega ADK+Ethernet shield+CNC Machine!!

Hello fellows

I was recently controlling CNC machine using Arduino Mega ADK controller...I done the control of all 3-axis by writing a simple code on arduino as shown below, So i need to control it now online using Ethernet shield and whenever i try to combine my program and Webserver program, i can't get any result...any suggestions please cz am cracking my head 2 the wall for 2 week 😔:

int i;
 
digitalWrite(dirpin1,LOW);
delay(1000);
 
Serial.println("Forward");
for (i=0; i<10000; i++)
{
digitalWrite(steppin1, HIGH);
delayMicroseconds(500);
digitalWrite(steppin1, LOW);
delayMicroseconds(500);
}
digitalWrite(dirpin3,LOW);
delay(1000);
 
Serial.println("Forward");
for (i=0; i<5000; i++)
{
digitalWrite(steppin3, HIGH);
delayMicroseconds(500);
digitalWrite(steppin3, LOW);
delayMicroseconds(500);
 
}
digitalWrite(dirpin2,HIGH);
delay(1000);
 
Serial.println("Down");
for (i=0; i<15000; i++)
{
digitalWrite(steppin2, HIGH);
delayMicroseconds(500);
digitalWrite(steppin2, LOW);
delayMicroseconds(500);
 
}
digitalWrite(dirpin1,LOW);
digitalWrite(dirpin2,LOW);
digitalWrite(dirpin3,LOW);
delay(1000);
 
Serial.println("Forward & Upp");
for (i=0; i<10000; i++)
{
digitalWrite(steppin1, HIGH);
delayMicroseconds(500);
digitalWrite(steppin2, HIGH);
delayMicroseconds(500);
digitalWrite(steppin3, HIGH);
delayMicroseconds(500);
digitalWrite(steppin1, LOW);
delayMicroseconds(500);
digitalWrite(steppin2, LOW);
delayMicroseconds(500);
digitalWrite(steppin3, HIGH);
delayMicroseconds(500);
}
digitalWrite(dirpin1,HIGH);
delay(1000);
 
Serial.println("Reverse");
for (i=0; i<10000; i++)
{
digitalWrite(steppin1, HIGH);
delayMicroseconds(500);
digitalWrite(steppin1, LOW);
delayMicroseconds(500);
}
digitalWrite(dirpin3,HIGH);
delay(1000);
 
Serial.println("Reverse");
for (i=0; i<10000; i++)
{
digitalWrite(steppin3, HIGH);
delayMicroseconds(500);
digitalWrite(steppin3, LOW);
delayMicroseconds(500);
}
digitalWrite(dirpin2,HIGH);
delay(1000);
 
Serial.println("Down");
for (i=0; i<10000; i++)
{
digitalWrite(steppin2, HIGH);
delayMicroseconds(500);
digitalWrite(steppin2, LOW);
delayMicroseconds(500);
}
digitalWrite(dirpin1,HIGH);
delay(1000);
 
Serial.println("Reverse");
for (i=0; i<10000; i++)
{
digitalWrite(steppin1, HIGH);
delayMicroseconds(500);
digitalWrite(steppin1, LOW);
delayMicroseconds(500);
}
