The gobo switching thing might be from the way your lights are addressed. They should be 1, 5, 9, 13. 4 channels per light. Now, try that, and select the 4 lights on your DMX Op with the fixtures buttons (left side, two rows of 8). Move the first slider, they should all move. And second slider and so forth. When the others werent moving, it was because they had the wrong address. Lights need to be addressed properly, or they wont recieve the correct signal, its like mail. Wrong house number, you wont get your bills. hope this helps!
