Great that somebody started this thread. I've had my FF for about a week now, and I love it. The only thing that's causing me significant frustration is that second nozzle knocking the model off the platform, or at the very least messing it up to the point where I have to start over. I've leveled the build plate multiple times and it just keeps doing it. Not all the time, but certain models (especially taller ones) seen more susceptible. I'm seriously contemplating removing that second nozzle completely for the time being. For right now, there's simply no point in having it. I'll just keep it in a safe spot for when I decide I need the second extruder up and running.
