Saw the question and it reminded me I needed to update everyone on my machine. I wrote a while back about my brand new Singer Quantum breaking needles, driving me crazy. The nearest authorized Singer repair shop is pretty far away. I finally took it to my local guy, who has kept my other machine cleaned and running for ages. He was an authorized Singer dealer and repair shop before they took away his franchise because he didn't sell enough machines. Anyway, I went to him, and he discovered the hook was not in the right spot, and adjusted it, runs beautifully now. It probably came from the company that way. Much more pleasant to sew and not cuss:) :)
