Sensormatic free-motion
Activate to set the machine in Sensormatic free-
motion mode for, e.g. Embroidery/Sensormatic
free-motion foot 6A.
When sewing free-motion at low speed the presser
foot will raise and lower with each stitch to hold the
fabric on the needle plate while the stitch is being
the fabric while sewing.
Skipped stitches can occur if your fabric moves
up and down with the needle as you are stitching.
Lowering the presser foot height will reduce the
space between the presser foot and the fabric and
eliminate the skipped stitches.
To adjust the presser foot height in Sensormatic
free-motion mode, long touch the check box and
make adjustments in the pop-up.
Note: Be careful not to reduce the presser foot height too
much. The fabric must still move freely under the presser Presser foot height
foot.
Do not use a spring foot if Sensormatic free-motion is
activated, since the needle might damage the presser foot.
