Well if this is a change from the way it used to work, then it could be the culprit.
From your last post, it all works well on the x and y, but not the z axis.
I would check for continuity form the z motor wire to ground and each other when shaking the wires. sounds like you have a short between the 2 power wires or to ground. both of these will blow a drive almost imediately.
It would only take one stand of copper wire inside a connector or something stupid like that to pop the drive.

I would also consider talking directly with gecko for more suggestions before you blow anything else.
