I know that there has been a few folks looking for an easy way to turn on and off your servos in VSA. Here yo go!!!
Just buy a PWM or RC hobby relay and connect it just like a servo --> run your positive lead from your servo power supply to the contacts of the relay, then take the other contact lead to the positive lead of your controller. --> Setup your routine with a quick command to turn on the to the power new servo saver relay. Then just shut it off with another command when the routine completes.
