A needle broke while I was sewing some curtain hems on my Baby Lock Soprano, I picked the needle tip out of the fabric. When I went to sew again it made a racket.
So I took out the upper thread and bobbin thread, removed the entire face place and bobbin case, and I cleaned all areas carefully. I used a soft brush to remove all lint (no needle parts found), shook the machine gently while holding upside down, no needle parts found.
When I reassembled, rethreaded and sewed again I got intermittent loops on the backside that run about 1 inch long with 2 inches of "normal" tension loops in between.
See pictures.
Do I need to replace the bobbin case? Should I adjust the lower tension?
