Does your friend who has the Expression 4.0 free motion quilt on it. I have one and bought it for free motion quilting and it is awful. The thread breaks constantly. I can't even free motion quilt one block without the thread breaking at least 8 times. It shreds the thread. I have tried every kind of thread you can imagine. I have had the dealer look at it several times and he did put about 6 factory fixes on the machine. Still no good. I am so disappointed with this machine but am stuck. I wanted the longer throat and scissor cutter that's why I bought it. It works well for piecing but not free motion quilting.
