As far as the blown cap's scrub everything on the circuit boards.
The goo inside is corrosive, so if you didn't lose your Geckos
today....


How did you have the motors wired ?

and as far as guessing what went wrong, who knows. I blew a Gecko
for some unknown gremlin. it ran the motor for a few days, I was
running and POP! you are correct, it is impressive when things blow
up.

A new gecko and it ran on and off for almost a year before I changed
motors and the wiring.

I did have the wire on the table so it was moving and twisting as the
table moved. best I can think was one strand did something odd, or
the shield touced the machine....

never could find anything wrong, but it works now. : )
