Babylock Tiara bobbin problem
Hello, I am knew to Long arm Quilting. I just bought a used Babylock Tiara from a friend who upgraded to an Avante on a frame. I've been trying to practice, but I am having a problem with the bobbin. I'm sewing along at a comfortable speed. I stop to check out the back and everything looks great! I start up again and my bobbin makes a noise. I stop machine, pull bobbin out, and find the thread came out of the tension slit and is wrapped around the post inside the case! How does that happen? What am I doing wrong?
I contacted the shop where she purchased it (last Nov) and they won't help me. They said if I bought it used, there's no warranty. I just wanted to know if I was using the correct thread, needle, etc.
I then logged on to Babylocks website, sent them an email... They won't give me a clue without looking at it. Huh?
I don't think it needs repair. It worked fine until I slow down or make a loop.
Can anyone help me??? Please?
