My Ender 3 Pro doesn't print
I am not able to print with the Ender 3 Pro. I have followed all the steps of a tutorial, inserted the filament, some filament came out of the extruder, but without any structure, and it was not adhering at all to the 60 degrees hot flatbed.
In the tutorial there was a menu point "Change filament" that doesn't exist in the menu of my printer!
What do I do wrong.
Where may I find a good tutorial to solve that problem?
