Problems configuring a big printer

Hi Repetier
Thanks for all previous responses
I now have another problem. I am attempting to connect  nema 23 stepper motors (8 wires wired in series) to an arduino due board with the repetier firmware installed.  I used the on line firmware generator and uploaded it to the board as far as I know successfully.   I have tried to test the motors but although there seems to be power going to them they do not respond to move commands on the host software.

Do all the endstops, thermistors, heated bed and hot ends need to be connected before it will move?

Am I missing something in my attempt to connect this machine?
