Thank you Martin! Finally I got it! Your advices about HOME POSITION were right to get the the print on the bed center!
After I've made all improvements on my config.h I didn't get any results concerning "layers shifting"... I had the doubt that the problem might have been on gcode generted from Slic3r, so I decided to make a gcode from Cura and I got my cube!
Cube measurements are pretty weird, I need to do a fine tuning on the printer, but I didn't have the shifting problem!
Thank you so much my friend! I'll add my remake on my profile very soon!!!!
