Servo Failure

Morning All

Today I upgraded to the latest software but now all my servos have stopped working. I rebooted both EZ and my laptop and rebuilt my servo controls but I get no response from any of my boards.

Has anyone encountered something similar?

Thanks,

Thanks Nomad. I'll check them out. The ones I originally used had a funny insulated block mid-way down. No idea why and they worked previously. I'm notorious for blowing circuits. An expensive hobby but I'm learning.

Alan I have a growing pile of dead servos I plan on using for an art project :-)

In general, when servos blow, it is the circuit board but not the motor, so you might be able to re-use the motors with cheap H-bridges, or as replacement parts on the rare occasions when a motor rather than a circuit board blows out.

But yeah, I have seen my share of expensive blue magic smoke in this hobby....

i only by here my parts.then am sure i got the wright ones, and warenty just incase.

my first bioloid i burn 10 servo's in one download,so your not alone. but it was also the fault off the seller,he was not annest man, and i say this whithout saying what he really was.

i always say,the more you break the more you learn.

The three wire cable if servos prevents them from blowing when plugged in backwards. You'll never damage a servo by connecting it backward. The ezb also has isolation resistors on the io to prevent backward servos from damaging the ezb.:)

If the servo doesn't work, it's been used and abused. Which is quite common for custom built robots. We're always trying to lift too much weight:)

DJ, that statement contradicts real life experience. I have two blown servos and the only abuse was plugging them in wrong.

Problem resolved on the servo. I severed the wiring close to the servo, replaced it and the signal connected. I must have damaged it.

Nice work! Little things like that are hard to find. When trouble shooting i always start with a simple voltage or continuity check to see it the power is getting from point A to B. You would be amazed how often that this is the problem.
