Re: DART actuators moving at different speeds

Is there any way to fix this or should we try to control the SRX on the PWM and see it we can calibrate them?
The first thing I would check is the gearing currently in the gearbox under the actuator. If you received them in two different shipments (or received the wrong gearing in one) there may be a discrepancy in the stock gear ratio. If not then I would suggest testing both actuators on the same talon, to make sure you don't have a faulty Talon or an error in your speed control code. If the two actuators are still running at different speeds then you may have a faulty actuator.
