Safety Rules

  • Always wear safety goggles when operating the laser.
  • Make sure that you have fire-extinguishing means at hand in case of an unexpected fire.
  • Use the laser on your own responsibility, at your own risk.
  • Never aim a laser beam at anyone and use it only for its designed purposes: laser cutting/engraving machine.
  • Never leave the laser unattended to avoid accidental fires and careless actions of humans and animals.
  • When choosing the material for work keep in mind that during the laser operation combustion products are released, which can be harmful to health.
  • Always use an air funnel and ventilation.
  • If you plan to cut any material underlay a piece of metal to protect the worktable from damage and fire.
  • If you are not sure about anything, please contact us (email, fill the website form or call).

Important facts:

      • Endurance lasers purchases components for lasers on an open market, therefore, we can not guarantee that all components are branded.
      • We do all the necessary tests before shipment to make sure that the product is reliable and meets presented parameters and is capable to do things presented in our video examples.
      • Endurance lasers design may vary to what is shown and presented on-site.
      • All engraving and cutting parameters may vary and are shown as an indication of our own results and results that were obtained by our customers.
      • Read the manual for your 3D printer or a DIY before installing the laser. We suggest connecting the laser to the fan or heater outputs. MakeBlock / DIY / CNC devices usually have available connectors for the laser.
      • Run a G-code to operate the laser on a 3D printer. (Learn more about g-code >>>)
      • All Endurance lasers work out of DC power supply (9-24VDC).
      • Laser power consumption (for 12VDC ):
        • A 2.1 Watt – 2A
        • A 3.5 Watt – 3A
        • A 5.6 Watt – 4A
        • A 8 Watt – 5A
        • A 8.5 Watt – 6A
        • A 10 Watt – 6-7A
        • A 10 Watt+ – 8-10A (total)
        • A 20 Watt – 12-14A (total)

3 Element lens focus:
Laser beam spot 400*600 uM (0.4*0.6 mm)

G2 lens focus:
Laser beam spot 300*600 uM (0.3*0.6 mm)
Learn more about laser beam spot >>>


Keep in mind to operate the laser and get the best laser cut and accurate laser engraving you must set up a perfect laser beam focus.
Explore about laser beam focusing >>>

We also suggest using air assist for deep and accurate laser cutting >>>

Always use fume extractor if you are cutting plastics or any hazardous materials.
