Yes, I did buy mine "used" from a dealer here in my city. He gave me a 90 warranty...came out 2 times before the warranty was up. Seemed to be fine when he left. But, I've always had tension problems with each quilt...have to work a while to get it just right. But, never like this. So, I guess I'll have to just call HQ in SLC next week. I just hate to give up....I'm a very patient person, and have always been able to troubleshoot and get it going. Not this time!! I have noticed from time and again, that when my bobbin gets low or runs out, I have problems. Get a bobbin filled and get back to it, and the tension adjustments start all over again. Crazy!!
