I've made progress with this problem, but it is not solved. The first time I went back to sew with it, it made a loud noise and the spool almost jumped off the spool pin. I removed the quilt from the machine and opened the bobbin area. I found a mess, including that the bobbin assembly had jumped out of it's position. There were random thread pieces and a small bit of lint. I had cleaned it thoroughly when I put that bobbin in. I took the needle out and found it bent from that incident. I changed it for a Singer 16 needle. I had already decreased the pressure to 3 before I started the seam.
BTW, I am using the same thread in the bobbin as on top. I have followed the manual for threading instructions.
Things were fine until I tried to sew fast. Then every time, the thread frayed and snapped. I have noticed that this machine will do exactly that when I sew fast no matter what thread or needle I use. I am beginning to think that the problem is the sewing speed, or when the motor first starts. Does anyone know why this is happening?
Thanks,
Cricket
