The issue is the processor used in the Raspberry Pis. They use a different architecture from the processor used in PCs. It is therefore not possible to run LightBurn on a Pi natively.
Another forum user has reported successfully running LightBurn on Windows 10 on a Raspberry Pi. This only works because Win10 includes a translation layer that converts the instructions from the PC CPU instruction set to the rPi CPU instruction set. This isn’t ideal and typically suffers slow performance.
