Yes. You can add an unlimited number of lasers to LightBurn. LightBurn supports three classes of laser: GCode, DSP, and Galvo. If you want to add a machine of a different class than the one you have now, you may need to upgrade your license. Visit: https://lbrn.info/add-dsp to add DSP machines to an existing license, and https://lbrn.info/add-galvo to add Galvo machines to an existing license.
