I have the Juki TL2010Q, and I use the hopping foot that came with the machine,as well as a modified Juki foot as per Leah Day, and also a Sharon Schamber non hopping foot. I usually use the hopping foot when my quilt has lots of intersecting seams. Today, I'm quilting a panel, so i'm using the Sharon Schamber non hopping foot. Whenever I have thread breakage or shredding, the first thing I do is lower the needle tension considerably.
Have you tried that?
