If that was my project I would have a variable to keep track of the required direction and it would be changed whenever a limit switch is pressed. Then the motor code would take account of that. Something like this pseudo code

void loop() {
  checkSwitches();
  moveMotor();
}

void checkSwitches() {
  if (leftLimitSwitch is pressed) {
    motorDirection = 'R';
  }
 if (rightLimitSwitch is pressed) {
    motorDirection = 'L';
  }
}

void moveMotor() {
  if motorDirection == 'R'
    stepRight
  }
  else {
    stepLeft
  }
}

...R
