Motors stop, console message k

Hello.

I have a problem with lightburn. Everything works fine after start-up, the motors keep running, but after a while, every time different (2, 3, 8 minutes) everything stops. Time goes on, but the engines stop working. On the console is displayed: Layer C00, o, Layer C00, k, Layer C00, k, Layer C00, k and stops. I am using arduino uno + shield, USB computer connection and win10. What to do with this ?

When does this happen? When engraving a photo or when cutting or filling?

I gave a lot of text and a few circles for testing

Please share your machine settings

I made another try, turned off all unnecessary programs in the win10


, turned off the internet, and then nothing. It went off after 3 minutes, though the clock continued to work.
