Hello Margo! I have the Bernina 750 QE (without embroidery module). I've had it a very short time..it's brand new. We were at the Northwest Quilt, Craft and Sewing show last weekend, and while there spoke with the folks at the Quality Sewing booth where they were demonstrating the Bernina 750. The gals there thought that all that was needed was to un-highlight the box around the little knot symbol that represents secure stitch. I did that in several places, but when I began stitching it would still do a secure stitch at the beginning. I gave my name and phone number and was told they would speak with the Bernina educator but I never heard back. Their machine behaved the exact same way mine did, at the quilt show. All of the knot symbols were de-selected and their Bernina 750 would still do a secure stitch when it began to sew. They were as stumped as I was! There has to be a way for the machine to begin sewing a straight stitch without sewing a secure or locking stitch first. Thank you for any help you can give with this!
