Amazing and well explained. I wish I'd found this video a few days sooner for the sake of my sanity. Your "bad case" example is exactly what I'm seeing on my embroidery back stitches but only when I'm sewing a horizontal column. While I can't find anything visually wrong with the bobbin I'm going to replace it tomorrow and see if that fixes the issue.

Thank you for the compliment, Im glad it helped! Good luck hopefully a new one will fix it!
