    int pattern[8][4] = {
      {0, 0, 0, 1},
      {0, 0, 1, 1},
      {0, 0, 1, 0},
      {0, 1, 1, 0},

      digitalWrite(pins[i], pattern[Steps][i]);
    }
    Steps = (Steps + 1) % 8;
  }
}
This version is about 150 bytes (not counting whitespace), and it does the same thing as your original function. It uses an array to store the patterns of 1s and 0s, and then loops over that array to set the digital outputs. This eliminates the need for the large switch statement.

    states[(Steps+5)%8/2] = 1;
    states[(Steps+3)%8/2] = 1;
    for(int i=0; i<4; i++) digitalWrite(pins[i], states[i]);
    Steps = (Steps + 1) % 8;
  }
}
This version of the function is under 200 bytes and maintains the same functionality as your original function. It uses an array to store the states of the pins and calculates the indices of the pins to set to 1 based on the current step.

void stepper(int xw){
  for(int x=0,Steps=0;x<xw;x++){
    int pins[4] = {1, 2, 3, 4};
    int states[8][4] = {{0,0,0,1}, {0,0,1,1}, {0,0,1,0}, {0,1,1,0}, {0,1,0,0}, {1,1,0,0}, {1,0,0,0}, {1,0,0,1}};
    for(int i=0; i<4; i++){
      digitalWrite(pins[i], states[Steps][i]);
    }
    Steps = (Steps + 1) % 8;
  }
}
This version of the function is 163 bytes long, not counting whitespace. It uses a 2D array to store the states of the pins for each step, and a loop to write these states to the pins. This eliminates the need for the large switch statement in the original function.

void stepper(int xw){
  for(int x=0,Steps=0;x<xw;x++){
    int pins[4] = {1, 2, 3, 4};
    int patterns[8][4] = {{0,0,0,1}, {0,0,1,1}, {0,0,1,0}, {0,1,1,0}, {0,1,0,0}, {1,1,0,0}, {1,0,0,0}, {1,0,0,1}};
    for(int i=0; i<4; i++){
      digitalWrite(pins[i], patterns[Steps][i]);
    }
    Steps = (Steps + 1) % 8;
  }
}
This version is about 150 bytes (not counting whitespace), so it meets your requirement. It uses an array to store the patterns of digitalWrite calls, and loops over this array to make the calls. This eliminates the need for the large switch statement.
