Laser Cutter: “Ultra Secret” Machine Operation


Reminder of steps:

  1. Create or open your file in lightburn
  2. Laser workspace should be completely clear. 
  3. Press the silver on button labeled ‘Control Switch’. Laser, chiller, and vent fan will turn on. Wait until laser initialization sequence is complete and no parts moving.
  4. Check that the chiller under the desk turned on by looking at case LED display. Check that ventilation system turned on – you should notice an audible vacuum noise. 
  5. Gently lift the lid all the way open (pneumatic assist slams the lid load and may bump mirror alignment) and load your approved material.
  6. Use the arrows to adjust bed height. Use the wooden focus tool between your material and head to get the correct height.
  7. Set X/Y position of head to desired position above material and click ORIGIN button on laser.
  8. In lightburn use the trace tool. The laser will outline the area where it will run. It should always be over your material. Adjust origin position or lightburn settings as needed.
  9. Use weights to flatten warped material after being certain from trace that the laser head won’t collide.
  10. Close the lid. Turn the nuclear launch key to engage the beam. Red button will light up.
  11. Press Play in lightburn or send file and run from controller.
  13. Turn off beam key, open lid, and retrieve material. Clean up scraps still on honeycomb.
  14. Turn off the laser using silver ‘Machine Control’ button.

Pause Button – Stops laser but job can resume.

Emergency Stop – Shuts down the laser, chiller, and vent. Push in and twist to release emergency button.
If you see your material catch fire (which you will, because you never left the laser unattended) hit the emergency stop, open the lid, and attempt to put out the flame by blowing it out, smothering, or moving the smoldering material outdoors. If the situation got out of control, use the small white halon fire extinguisher.


Our laser focuses beam width is the smallest and strongest at 3.7mm from the nozzle.

  • For marking/etching raster images with the highest quality set the bed height 3.7mm away from the surface of your material for the highest level of detail. The Blur heights on the tool can be useful for getting large darkened markings in areas that don’t require precision.   
  • For cutting, it’s ideal to have the strongest part of the beam be in the center of the material. The focus tool has presets for the center of 1/8″ and 1/4″ material. The optimum focus distance may vary for different materials, so you may need to experiment and find what works best for you. Using the optimal focal distance for your material width also reduces kerf. Due to our lens focal distance you should not cut any materials thicker than 1/4″.
  • For engraving slightly into the surface you can play around with using different focal distances. The 3.7mm focal distance has such a small beam width which results in many ridges despite cranking up the interval/DIP. It may look better to use 6.8mm which will result in a smoother looking fill (at least on wood).

Example of how different focal distances create different beam width sizes.
