  a. Disconnect air intake. Push in the white ring and then pull the air hose out.

  
  b. Clip the white electrical tie around the white ribbon cable.

  
  c. Disconnect white ribbon cable.
  d. Unscrew the green captured screw on the left side of the X-beam.

  
  e. Unscrew the two green captured screws on the right side of the X-beam.

  
  f. Lift the I-beam carefully. Use caution when lifting the right side of the X-beam. Bring the right side forward a little to ensure the motor clears the frame rail.

• Place the X-Axis Assembly on a clean table top. Make sure the Laser head does not rest on the table.
