I have a computerized machine also, a Babylock. I made it a habit to always press the reset button any time I am changing presser feet, anytime I am changing from one decorative design to the next. and anytime I go from embroidery back to regular sewing, and vice versa. The machine goes back to the default set up of straight stitch, needle in the center, and presser foot height back to default setting also. Then I press the needle up button to make sure that is done for changing threads and presser feet.
