I2C slave reply

Hi Paul ,
Thanks
This seems to work for me .
But I had to increase my delay in the master to a value greater than 5000 . If it is lower , the stepper motor just doesnt run .
Would you be able to explain why this happens ?

And also ,
if I was to replace ur code with

while(Stepper1.currentPosition() != Stepper1.targetPosition()) 
   { //Wire.send("Action not complete");
   }
   digitalWrite(4,HIGH);
   Wire.send("Action complete");

then shouldnt it send "Action not complete" continuously ?
