Okay, so I have four moving heads which sit on the floor in a row. I'm using 30w mini LED Spots in DMX mode running through myDMX Buddy 2. Lets say I have all of them pointed at an object on a wall in one scene. I run through a couple of other scenes where the heads are performing rotational or random movements of some sort. I then go back to the original scene where the heads are pointed at the wall object, only this time they're all off target by a few inches or more.

I'm wondering whether or not this is a result of the motors in the heads moving quickly and then coming to a sudden stop? Almost as if the motors/belts inside nudge off axis just slightly due to all the movement..? I've gone through most all of my scenes and changed the fade time for them to about a half second, and that seems to have helped a little, so they aren't just ram-jamming into the next scene to a sudden stop.

But I still have a couple of scenes where there's a lot of fast rotational movements, which seem to throw the lights off their targets about an inch or so. Would it be wise to reset those chase durations to something a little slower to help remedy that? Just looking for thoughts, opinions and tips. Thanks

How secure are the lights? If they're smaller units, and just resting on the floor, the momentum of the head spinning around and suddenly stopping may shift the base minutely. If the base shifts even a couple of degrees, the beam will end up inches or even feet off target, depending on how far away the target is. I'd look at that, first, before getting into whether or not the internals are dropping out of calibration.
