Singer Sewing Machine - Quantum XL 6000 - Computerized Review

I have the XL6000 Singer sewing and embroidery machine . I have had it worked on twice for thread wraping around the bobbin case.Ihave found the tread from the automatic bobbin does not always cut the thread  If you watch the spool to see if the thread is moving when the machine starts back ,cut the machine off and cut the thread. You can remove a small amount of thread with a small blade and tweezers.When your bobbin gives out you will have to rethread, a little inconvenence but will save $200.I am calling singer today to report this problem.
