I own two lasers. One 2.5 W RGB Analog one 600 mW RGB TTL. When I run the 2.5 W on "Sound mode" I get a MUCH larger projection size than when I run it with my QS FB3 card. I reset everything on the software, zones, sizes, etc... I have found it's probably 40% smaller with FB3 than when it's running by itself. Note: There's two pan pots on the back with X and Y dimensions, both turned up to 100%. When I run the 600 MW it's a large projection size. I can push it even harder when it's connected to the FB3. Probably to 110%. My question is: Why isn't the FB3 accessing the full potential of the 40K scanners on the 2.5 W? Could it be that the pan pots are affecting it? Is disconnecting them a possiblity? Any info would be greatly appreciated. Thanks!
