Laser works then goes to busy

Hi guys new to this have got the k40 laser with gerbil controlleri have been using for 6 months.
But just today the laser starts engraving then stops after a couple of min and goes to busy

You have not provided which version of LightBurn nor the OS you are using, so this is just a guess, but if you are using USB as your connection to a Windows machine…this might help.
