I have two of the same machine one sits on the "Next Generation" quilt frame & the other piece with. When I FMQ with the machine on my sewing table no issues, on the frame the thread breaks every few inches. I have tried changing the needle, different threads and adjusting the tension and pressure foot. Still the same frustrating situation! I reached out to the dealer thinking I would get rid of the frame and one of the machines but he won't take it back. What does that say! I have even visited Pfaff website nothing there at all. Personally I feel like I wasted my money on this purchase, lesson learned.
