Quattro 6000D challenges and issues
I purchased a Brother Quattro 6000D and upgraded it to the latest and greatest with all three upgrades. I intentded to use this machine for embroidering quilt labels utilizing the embroidery design functions. I also intended to use if for free motion quilting and quilting with embroidery designs. So far it is great for piecing because it sews basic stitches great. But I have trouble with the "fancy" stitches and using the free motion quilting functions because the bobbin thread bunches up on the bottom of the fabric. Nothing I do seems to solve the problem and brother technicians are of no help. Has anyone else had these types of issues? What did you do to solve the problem?
