Yes, I think the Z drive is popped, but you should check the Z motor for possible intermittent short to ground. Doesn't make sense that it blows fuses, then you move the drive and put back, and it DOESN'T blow fuses anymore. (Of course, whatever was shorted and blew the fuse may have been burned clear during that short, so it doesn't pop fuses anymore.)
