prining is no pssible

All Funktions are runing at the first look:
Leveling, feeding filamet, conneting, loading Projekt.
but every time i try to print, after max 60sec the party is over, the printer cuting the connection, stop printing and the display falls in in an endless startup grafic…
after 5 hours of trobbleshoting, i m at the end… and need help…

I had trouble at the beginning. Why don’t you record a video of everything that you are doing to setup and when the error happens. It might be easier to understand what could be the problem.
