Most often when I get the nest, it is when I forgot to lower the pressure foot or the thread slipped from the tension spring --- I also had an issue with the thread breaking every several inches. When I was talking to the store, He suggested to check the level of the bars and make sure they were not too high. Bingo. I lowered the bars to sit on the machine so the quilt sandwich was not floating and it was smooth for rows at a time with out the thread breaking. I have seen responces that suggest that the quilt sandwich should be at least a finger from the surface of the machine, but with my setup it works best when the top has no bounce. I also just bought new needles, size 14. I am hoping this also makes a difference. I was using size 11. --- My machine also worked beautiful off the frame. I hope this helps.
