I have tested everything and it homes perfectly. I have tested everything and it homes perfectly. However, whenever I press Z- or send g code commands like G1 Z10 F1000, it won't stop coming down. It just keep moving downward until I hit Emergency stop button and i press z+ button then it moves perfect. How do I solve this? 
Every help has a great meaning to me!

    Oh, sorry! My printer is delta type. I use repetier fw, arduino mega and ramp 1.4. All my endstop at max position

    After homing check position with M114. My guess is that z length is much too high so z=0 is below bed level. Start with G1 Zxxx where xxx is some mm lower then what M114 returned.
