The 2.0 and Artisan are running Marlin, whereas the Ray is running GRBL. However, they must have taken points from my old guides and made their profiles as GRBL since it works fine (except the GRBL specific commands naturally)
Despite being Marlin, I’ve always used GRBL as the device in Lightburn for my 2.0. It’s also how I’ve stated to setup the machine in my guides as well.
