Pigi,
First put power on the board without it hooked up to the pc or driver boards. LED1 should illuminte. Hopefully you saw the errata in the document and installed a jumper inplace of LED2 ? Assuming LED1 illuminates, LED7, LED9, LED10, and LED11 should not. If those verify, placing a jumper accross Xhome should illuminate LED9, placing a jumper accross Yhome should illuminate LED10, placing a jumper accross Zhome should illuminate LED11.
If all is well at that point jumper pad1 or JP4 pin2 to 5VDC pad, when you do that LEd7 should illuminate.
