I know what are the endstops. I assembled my ultimaker original by myself. I realized I have the same problem on the z axis. I tryed to print an object, it starts ok and finish to print in the air! The ulticontroller say always endstops hit (for all axis), soI would to know what can i do for solving this problem. Thanks!!

Hi, i have a problem with the endstops of my ultimaker original: the ulticontroller says "endstops hit: x" and if i move extruder along the y axis, the ulticontroller says also "endstops hit: y"!! What does that mean?? Anyone know the reason? Thanks a lot!
