Hi Pam, I keep my Mega Quilter on the frame as I have another one that I use for piecing. As suggested check to make sure that you have threaded it correctly and that the tension dial is set between 2-3 when you lift up the pressure foot. For the longest time I was using Mettler thread which started to break on me also. I went to my quilt store and the ladies there suggested that I try Presencia Thread and it works great, but you need to clean out the bobbin area. Let us know if this helps. Have fun quilting
