Ortur Y-Axis rotary roller

This error keeps coming up on my Mac

“There was a problem sending data to the laser.
The machine may be busy or paused.”

I’ve rebooted Mac and laser, set laser up on my laptop using
laser GRBL soft-ware that seems to be working fine, just can’t get Lightburn to work any more

If you have a connection problem, you will get a message saying ‘the laser does not appear to be connected’, so it knows the machine is there and is getting a ‘busy’ message. (I’m on Mac too).

If you look at the console panel, what does it say?
