A little more iformation would be helpful. Like are you going to run expantion boards or power inject. Ect. At 3000 pixels per board its aprox 168 pixels per port which will require additional power considerations. But as far as setting up in xlights its easy . Whatever channel number you end with on the first board, lets say channel 9000, The next board will be starting at 9001 if you want it to continue like that. Lots of channel options available as well . Its just how you want to set it up.
