Hello quilters. I am interested in getting some help with my Sapphire 830. It seems to work great except for the fmq. After surfing the internet, I guess this is a common problem on some of the machines. I did have it into the dealer and they couldn't fix it. Anyway, the thread keeps breaking. Am using embroidery thread (dealer recommendation) as the cotton kept breaking also and didn't seem strong enough. I have tried moving the spool around in different positions. Sometimes it helps and other times not. I did have the tension bar attachment upgrade put on to keep the thread from coming off. It does do that but still the thread ravels and breaks. Any help would be appreciated.
