I do turn my machine off any time I walk away from it, and when I do, it resets the stitch to the default, so I have learned to keep a stack of post-its next to the machine, and as I start a project, I write down the settings and stick it to the top of my machine. That way if I have to sew something else real quick, or turn the macine back on, I can go right back to the proper settings for the stitches of what ever I was working on, and I don't have to try and remember the settings.
