| I was wondering if there is anything I can do to prevent signal bleeding that occurs across servos. I am only using two servos on a pan/tilt assembly. The pan servo is continuous rotation. I noticed that all of the servos will twitch when calls are made for a change of position to any one servo. While this doesn't have "as" adverse affects when using standard servos, it does create major issues with a continuous rotation servo as the position call to the servo is much like that of a motor. When the tilt servo reaches a certain point, bleeding starts to occur chaning the position of the pan servo causing it to spin uncontrollably. Is there anything that can be done to the leads to help prevent this bleeding? A resistor, maybe? Is this something common to the serializer, or maybe an issue with just my board? Not sure if it helps, but I am using a constant power supply of 12v at 2a. Thanks for any help that can be offered.

| The issue may be the power supply. servos can draw a couple amps each when loaded. So if the pan gets to a certain position where it is a little more stressed, then the voltage may e drooping enough to confuse everything. I would try either a stronger power supply, or a battery. If neither of these are an option you can try a large capacitor at teh power inputs of the serializer to see if that helps. Ringo
