Another thing to consider...perhaps your machine doesn't like the particular kind of batting you are using??? I find FMQ is much easier with some batting than others. My favorite is "80-20" (80% cotton, 20% poly) because I like the way the quilt drapes, and it is easy to sew. I also use Warm and Natural 100% cotton, and a few varieties of poly. I hear from others on this board that bamboo batting can be troublesome...
