hm… I just saw that my console dont stops writing:

"Attempt to move the head of a delta printer before homing the towers"

What could be the problem ?

What it says. You tried to print before you homed the printer. Or you turned the motors off at the end of the previous print, so the firmware can't be sure of the head position any more and you need to home it again before you do another print.

Some people use G28 in their slicer start gcode to make sure the printer is homed before printing.
