Funny, I just happen to have one of these in front of me and I just happen to come across this thread without searching for it. I cant decide ether to get it working or scrap it for parts, it seems bit of a money pit. Nonetheless I look forward to your progress with this machine.

P.S TB6560; I heard nothing but bad things about these drivers, after wasting money on them I have brought 3 Pololu a4988 with a Arduino CNC shield to use with my TEP unit.
