Hi, New guy here. I sent the following to American DJ: Hello, I purchased a used American DJ DJ Scan 250 (serial 4632238). I am using an Enttec USB-DMX Pro with the latest firmware (v. 1.44), and LightFactory Basic (v. 1.4.0.047). I also have 4 Eliminator ED-15 Dimmers. The problem I am encountering is the DJ Scan 250 will respond correctly when commanded by the DMX system, but it starts randomly scrolling the color wheel and the gobo wheel. The wheels will settle back to the correct color and gobo, but continue to scroll at random. I also see a lot of random twitching in the mirror. The dimmers work flawlessly. I have a terminator on the last dimmer. I have tried various cables and configurations. I have even setup with a 2 foot cable to the DJ Scan and the terminator in the DMX Out. Nothing I do will allow the DJ Scan to be stable. What else can you suggest? And this was the response: "The Dj Scan is known to twitch a bit but I can only say t compare it with another DMX Controller." Is this correct for this fixture? Is there any hope of stabilizing it/ Is this a typical response designed to urge me to purchase a new fixture? Thanks in advance for any insight into this issue.
