Check your endstops with M119 in pronterface, most likely are triggered.

What is M119 and how i do it, do you have screenshot please i don't understant what you wan i do...

Just write M119 in the command line in pronterface and it will display the status of the endstops.

If any shown triggered without actually been triggered, change it's logic in Marlin.
