Fellas, i finally got it working,it was like the truman show, the problems were - the wiring inside the z axis motor was dodgy and loose, don't ask me how, the control board for the z axis was fried, again, i haven't got a clue, thankfully i had purchased a 5 axis control system but was only planning on using 4 so i had a spare, i'm now up and running, thanks a million for your help. Hopefully i'll post something in the look and tell thread in a couple of months.
