What Do I Do When the Bobbin Is Showing and Not Centered?

If the bobbin thread is visible on the top side of your embroidery design and appears off-center, the issue may be caused by the positioning finger not being properly aligned with the sewing hook.

The positioning finger helps control the orientation of the bobbin case during stitch formation. When it is not centered correctly, the bobbin thread may not be pulled evenly, resulting in unbalanced stitches and excessive bobbin thread visibility.

How to Check the Positioning Finger

1. Remove the throat plate to access the sewing hook area.
2. Locate the positioning finger and inspect its alignment relative to the sewing hook and needle.
3. If the positioning finger appears offset, loosen the mounting screw that secures it in place.
4. Carefully reposition the finger left or right, depending on the direction the bobbin thread is pulling.
5. Tighten the screw and perform a test sew.

Proper Alignment

For best results, the positioning finger should be centered with the needle and properly aligned with the sewing hook. Correct alignment helps ensure balanced stitch formation and proper bobbin thread placement.

If the issue persists after adjustment, inspect the hook area for wear, damage, or other mechanical issues that may affect stitch quality.
