X-Y Axis are moving but Z is not !!

Hello Im working on a Reprap Rostock 3d printer V1 and my current problem is, that somehow my x and y axis are movin but my z isnt reacting to any command(its also not getting too hot or something). Would be nice if someone could help me cause my time is running out.

Hi Paul

Have you tried your Z motor on another port and the Z port with another motor? Also check that the end stops are working by sending a M119 command as you click each one in turn check too that they are plugged into the correct port I.e the switch on the X tower is in the X endstop port. You may also want to check you have your X, Y and Z in the right order. Looking from the front the tower on the left is X (1), the tower on the right is Y (2) and the rear tower is Z (3). You have probably checked all that but going back to basics is the best way to diagnose a fault.
