After reading all your posts it sounds like its not you it's your machine. My post was going to suggest you take back to the dealer. Maybe the timing is off. But I see you've thought of everything. Make sure before you take it home that dealer has used it fir FMQ. I'm sure all will be well soon.

Well, I picked up my machine on Thursday. The problem was the customized quilting foot. I had changed it per Leah Day's suggestion and that was what was screwing up. The shop put on a new Janome quiliting foot (without customization) and it's now stitching beautifully! Well, as beautiful as a beginner can do. Lol. Thanks for all your suggestions. Kathy
