Hello Daid,
thanks for your reply, i've installed Cura and upgraded to Marlin firmware. During the Wizard the program asks to move the extruder and the other axes for checking, but i didn't find any way to do it. I tryied with arrows from the keyboard and by clicking to xyz home as shown on the left of the screenshot, but it doesn't moves. Also the heating of the extruder i've setted to 200°C, but it remain cold. Attached you find a screen shot, maybe you can understand what's wrong, for me all these things are very new. Thanks for your help.
Sorry, i forget the screenshot.
