I'm having some trouble with my machine, and I wanted to run it by the experts.
This is what my machine is doing when I set it for a simple straight stitch. I've changed the tension, and it has no effect.
It looks the same at other tensions. (Enlarge the thumbnails to see)
This end had a tail (extra thread) when I started, but I guess it got pulled along as I went.
Also, this is what it did to a three-step zig zag. The light blue was the spool thread and the dark blue was the bobbin thread.
In addition to messing with the tension, I've rethreaded the machine and dusted it out with compressed air, but nothing is working. It's a three-year-old brother machine, and I've never had this kind of trouble before. I've never even done a gathering stitch (on purpose, anyway). Any advice would be greatly appreciated!
EDIT: I just tried the dental floss thing suggested by cyndiq in this thread (http://www.craftster.org/forum/index.php?topic=312034.0
) and made sure the tension discs were catching the thread and actually changing the tension when I turned the knob. Still no luck.
I have a Brother LS2125.
