Alignment Procedure

• Normalize the laser to the burner surface
• Put the goggles on to view laser beam
• Use the LabView program to move the burner until
  the laser is aligned on the target
• Move the burner in the positive vertical
  direction 76.2 millimeters.
• Open COSMOS program provided by Velmex and set
  the zero position
