I have Janome 1600P and when I begin quilting I get a thread ball at the bottom of the quilt. Occ it knots so badly it won't move and I have to crawl under to get the bobbin out and begin cutting threads to resolve the gunoidulum.
Anybody have thoughts on WHY????????????????????
I HAVE OILED, CHANGED NEEDLES, ADJUSTED TENSION BOTH BOBBIN AND UPPER.
