Hi,

Servo i am using are: MX-64AR

I hope you guys could offer some advice, basically, i am making a robot arm and need 5 servos, 3 work completely fine but the other two do not, I have even tried to re-ID them and then RE set them but still no movement. I know my code is working for the resets as I tried them on the working servos (if reset is complete it makes the servo ID 1).

any suggestions? i have also tried the mechanical side of it, all the gears seem in perfect shape too.

cheers,

Mark

Ouch!
At that cost, 2 failures is painful!
Did they ever work?
Were they purchased new?
Does the seller offer any warranty?

They were indeed used before me in a past project, so i have no idea what happened to them! lucky for me its my university that deals with the price! i was just trying to fix them myself haha.
