I have two of the servo grippers with the mini servos.
When I first power up the EZB the servos make no noise.
After telling the servo to go to a position the servo moves to the position and stops but keeps making a high pitched hum as if the servo is still trying to move. This occurs no matter what position it moves to.
My other servos for example the legs does not do this.
The only way I can make the noise stop is releasing the servo using the horizontal servo control or ez-script.
Is this normal. I do not want to somehow damage the servos.
Any help is appreciated.
