I have the Juki 2200 QVP ... my foot does not hop.
I remember after I bought the machine I viewed Leah Day's video and one of the first things she mentioned was the hopping foot. (an aside ... I never did understand her aversion to hopping feet - My Janome and Husky both hop and they have never bothered me). I thought ... wait ... does my foot hop? So off I went to the sewing room and nope ... my foot does not hop.
I wonder if they modified the machine at some point? Or do I have a weirdo??
