I have a LO-X7 controller and it works great using Raycam. My current workflow is to save the UD5 file from Raycam onto a flash drive and use that to transfer it over to the laser cutter which is on the opposite side of the house in my workshop. When I use Lightburn the file is blank when viewed on the laser cutter. I read that Trocen controllers use different scramble keys and this can cause that. Is there a way to pick the scramble key to use?
