LightBurn Setup: After Your Machine Arrives (PC)

Updated November 12, 2026

Applies to: All CO2 machines, on a Windows computer

This guide shows how to install LightBurn with your license key once your machine has arrived, and how to connect to the machine by USB or Wi-Fi.

LightBurn is layout, editing and control software for your laser. It talks to the laser directly, with no other software needed. The device profiles created at the factory control how LightBurn connects to and communicates with the machine, along with other settings needed for proper operation.

What you need

  • Windows computer with Wi-Fi
  • Internet connection
  • LightBurn license key
  • USB thumb drive (attached to the ignition keys of the machine)
  • USB cable

Install the software and driver

Note: Before you begin, turn on the laser.

  2. Select your version of Windows from the list to start the download. If you are not sure which version you have, type “System Information” into the search field at the bottom left of your taskbar, and look at System Type to see whether it is 32 or 64 bit.
