I got this message showing up a few times today - “Transfer failed. There was a problem sending data to the laser. The machine may be busy or paused.” My laser has a Ruida controller and I connect to it using ethernet. It’s plugged into a TP-Link ethernet over mains wiring adapter, with the other end plugged into my router. It’s been working fine for 8 months, but today I hit this problem. I ended up re-booting the TP-Link adapter and after that it worked fine.
My problem is that each time LightBurn posted this error, the laser would start the job and then stop at some inconvenient point, leaving me with a half-finished burn - decidedly not good!. Is there any way that LightBurn could abort the entire job, if all the data doesn’t make it across from the PC? Or some other way of trapping this potential issue before it becomes a problem?
