Hi, matrix has scrambled signals, works in preview fine - both HLS PP and NC/XL effects. Am using pixlite4 , have tried simple & advanced string setup to no avail. Matrix is ink1003's 75 x 20 (XY), Hls is setup Left to right then right to left, starting top left corner as str1pix1. have tried all combinations of setups to get something to work but no luck, as said have output just scrambled , so I'm sure its something simple I am missing (as usual!!) Cheers Boof 63 PS inks are facing sun on both sides throughout the day, Backside has afternoon sun (Hottest period) can the 12 regulators etc handle the heat or should I place some shade cloth over the back to protect from direct sunlight??
