Ah, gotcha. You're such a bum. Actually, I started printing something the other day, and it turns out that my left extruder is like a half millimeter higher than my right, so if I print with my left, it just globs up on the extruder. I could just take 30 minutes to fix it, but any true lazy man knows that's not the best way. My solution was to unload the right extruder, load the left extruder's filament in, and just let it be. I actually just crossed the left extruder's tube over to the right, and left the right tube dangling. So how is that for laziness?
