I just purchased a pfpaff grand quilter 1200 last week, when I tested it in the store and did a test project at home with cotton thread everything was perfect.
So I loaded my quilt top, placed a full bobbin in, and wanted to use poly thread I kept getting thread breaks, and irregular stitches.
I switched to top stitch needles which the shop recomended. Can someone please give advice. I have a stitch regulator on the machine and getting non stop thread breaks and skipped stitches. I'm ready to take the machine back

Thank You
