I have an issue which is G-CODE its popping out as soon as i hit the print button.
Let me do a guess: You downloaded 3mf and did not change the Printer-Type?
I am sure you have an P1P/P1S.
Look at the Printertype 
Change it to the right Printer and Nozzle
Yes i got p1s . Where can i change the printer and the nozzle
