Help. Using the LED Scanner works great using our Light O Rama controller. Hower we are trying to do the same thing with a falcon controller and something weird happens. the LED scan works great, it appears that each dot is captured right where it is supposed to be, however, when you play a test Line slowly over the newly scanned pixels, they are randomly all over the place. it makes no sense. Any ideas?

No idea. You can verify the data being sent in the DMX Monitor inside MadMapper.
You can also try to deactivate synchronization packets ("Enable universe synchronization" in preferences / DMX Output). Some devices don't handle it properly.
Are you sending with ArtNet or sACN ?
