after more test,ad im look "heating done" im go to menu,select "print from sd" select my file .gcode (that file im sure it work at 100%) the 3d printer wait more minuts,after the bed go down,and % of print increase at 100% but head not move....when the % is arrived at 100% the head go out of zero point and remake the zero axist of x and y and not print nothing...but if im go on menu,prepare...move axis..1mm all axis move perfectly....
