I just purchased a Boss LS-2440. First, the LightBurn software doesn’t list this as an option in the BossLaser drop down. It does have the LS-2436 which Boss is no longer selling.
Second, I have tried to export the files I am working on to a USB to load onto my laser, but the machine will not recognize the file type. It seems that is requires a .rd file and I can not find that as an export function.
