I have a Hog 1000 used to light a small stage with 12 moving yokes (power spot 575 and accu spot ii), along with a large number of LED wash lighting fixtures. Over the past year, I have noticed that the moving yokes are "hunting" more and more. By hunting, I mean it is placed into a position, and sometimes it begins to twitch (either the pan or tilt) until it is slightly moved. I also have a few colors that are not available because of this hunting (e.g. I can not lock on to certain colors). This problem seems to get worse the longer the board is in use, so I thought it might be a heat related issue. I have never opened it up so I do not know if there are fans inside, similar to a desktop computer, that might have failed. Heat is only a theory; there maybe some other problem that might be causing the hunting, not sure. What I do know is this condition can be seen in all of the moving yoke fixtures (both the accu spots and the power spots), so I do not believe it to be a fixture library problem (and they have worked better in the past with the same library). I do not see it much (if at all) in the wash lighting. Does anyone have any ideas how to resolve this problem? Is there something inside that has failed that could be replaced?
Hello, if fixtures are twitching it could also be due to a data issue such as needing a terminator in the last fixture at the end of a data line, or a cable on the edge and starting to fail. You mention connecting a fixture directly to the console and I agree that would be then next thing to try. You can then add more little by little until the problem appears. You also mention the wash fixtures do not have this problem. Are they on the same data line/patched to the same output on the console, or are they on a different output? If they are on a different output in may explain why they are not effected.
