I have the same machine, are you sure you raised the foot when you threaded the machine, this releases the tension and allows the thread to seat in the tension disc's. Then when you lower the foot the tension is set. It looks like this is what is happening. Set your pressure & stitch length to 0, your speed to medium, make sure the thread is seated in the tension disc, slow down on your curves, buy the blue bobbin case and you should be good to go. Have quilted many fm quilts on my Janome and it does beautifully. Good luck
