  • I have several of these motors. At first I thought there was a problem as my initial experience was the same as several other contributors - eratic behaviour, jaming on the end stops, constant motion/oscilation etc.

    However, the problems were only apparent when driven directly from the Arduino UNO board - even with an independent power supply. On the scope the pulses intermittently have the trailing corner cut off, resulting in an inprecise pulse width.

    If you drive the servo from a Servo Controller or by powering the motor directly, then it works perfectly.

No public wish lists :(
