Re: [CAD_CAM_EDM_DRO] Is this a blown Gecko?

I'm sorry to say, but it sounds like you killed your gecko. Please call
the helpful folks at geckodrive.com. They have been known to replace _one_
for free, and are willing to try to repair it. If it is not economical to
repair, they will let you know. They know all the common failure modes,
but if there are any burnt traces on the PCB, it's not worth fixing.

Are you very experienced with a soldering iron? Several people have been
sucessful fixing their geckos by replacing the output transistors. I think
they are IRF 530s or 540s. The exact part number should be in the archives...

Hopefully in the next few months, the "vampire" gecko will be released,
which will be protected from common mistakes like the one you made.

Good luck,
