Ender 3 V2 print fails
Hello there, just built Ender 3 V2, everything good, I try to print file from SD card Cat3.5h I firstly set PLA and nozzle preheat to 200 and 60. Filament string runs out of nozzle after heating but after several minutes the filament is withdrawn nozzle goes cold and print does not start.
I have searched extensively online but cannot find any suggestions to help so far.
Any advise appreciated.
