2 Fried G210's in a single day :-(

Man.. this day is *not* going well.

I just finished wiring up my Brideport Boss with my new Gecko 210's.
I turn on the power.... Gecko 1 (X axis) LED glows dimmer than the
other two so I power off... re-check the connections and voltage and
power back on.... The drive is gone... no LED, no nothing.
So, I figure I'll get back to that later and I start playing with
the Z and Y axes...all is fine. Then I decide to wire up the limit
switches so I power off the machine, but decide to move the Z axis
which is very close to a limit for accessability so I power back on
to move the axis and WOWOWOW... My arc welder makes less sparks!
I have no clue what is wrong here. My voltage is steady at 72vdc,
everything seems to be wired correctly and I cannot detect any
shorts. In any case, now the Z axis is cooked (literally), and it
had worked fine not two minutes earlier.

I'm going broke at this rate. (well, I was already broke)
