New User HELP error 25

GRBL error:25 means that the GCode wasn’t received correctly - basically a command got scrambled. Check that all the wiring connections are secure, and try a different USB plug on your computer.

You should be able to run LightBurn on both Windows and Mac and get it working with your Ortur Laser Master 20w machine. This is not a LightBurn issue.
