Finally got around to reprogramming my etherdongles and I don't think EtherDongle2.hex is the right firmware either.
This firmware solves the boundary pixel problems, but it does not output the pixelnet smothly. With the first first etherdongle firmware, the motion on my sign was fluid, but with etherdongle2.hex, the motion is mostly jerky with stretches of smoth motion mixed in. Only difference is the firmware.
