LightBurn offers two main license types, determined by the controller your machine uses:

• GCode License: For machines using GRBL, Smoothieware, or Marlin controllers. This is typical for diode lasers, desktop CNC machines, and DIY setups.
• DSP License: Required for systems with Ruida, Trocen, TopWisdom, and similar controllers found in CO2 laser cutters and industrial-grade machines.

The license you choose must match your machine’s controller. A DSP license is not an upgrade to GCode — it is a requirement based on hardware compatibility.

Both license types offer identical software features, including:

• Full design and editing tools
• Real-time preview and optimization
• Support for file formats like AI, SVG, DXF, PDF
• Layer management, speed, and power control

The only difference is controller compatibility. Therefore, the license choice depends on the hardware you are using or planning to use.

For beginners using diode lasers or hobbyist CNC machines, the GCode License is the standard choice. Affordable and fully functional, it covers most personal and small business needs.

For professional users with CO2 laser machines, or those planning to work with industrial-grade hardware, the DSP License is essential due to controller requirements.

Before purchasing, verify your machine’s controller type. If in doubt, consult product documentation or contact your CNC machine supplier. Opt Lasers provides expert support to help you select the correct license.
