I also am having a problem with my stitch regulator on my Millie, not all the time, just sometimes. I'll be either working from the front or the back quite nicely, then all of a sudden it starts to "miss", then takes an uncontrollable number of fast stitches, then skips ... then if I start to move the machine slowly it will "get back to normal" stitching again. It scares the heck out of me especially when I'm working from the front of the machine with rulers. I just quilted a childs quilt the other day and it only happened once. I will try what JanieSue mentioned in the above post about the cable connection.
