    Could someone enlighten me as to why the drive chains are run so loose?

    Likely so that they can take the chain off easily to change the extruder die easier.

    Sorry but I fail to believe that. By the looks of things there is double the slack that would be needed for that. But, if what you say is true, then it is a very poor design. A better design would be a spring loaded idler.

    Changing the sprocket size will shorten or lengthen the pellet so I would say extra slack is for a larger sprocket that would result in a longer pellet.

    The cutter that the sprocket drives is really under very little load so the slack is of very little concern.
