    I know it's the foot control. It's a servo motor and I don't know how to reset the neutral postion.

CANT QUILT WITH MY JUKI TENSION PROBLEMS


Okay, you've tried a lot of things. The question is this: is the thread snapping (where abouts in the path), or is it shredding at the needle? Here are a few more:

Remove the top thread, ALWAYS RAISE the presser foot, and rethread from the beginning.
Try different thread--perhaps a polyester thread like Isacord or Aurafil. (AVOID old or bargain bin thread.)
Try a different kind of needle (brand new needle!)--like a top-stitch, microtex, or embroidery. The top stitch needle has a larger scarf that will better protect the thread if shredding is the issue. (I use a special bobbin case that I've increased the tension for Isacord thread and I use the same thread in top and bobbin.) I also decrease the top tension a tad so the bobbin thread will not pull to the top. You may need to install brand-new needles several times on one quilt when they get dull.
Usually an 80 or 90 needle will work for FMQ through a fabric/batting sandwich.
Check that the needle's eye is the appropriate size for the thread (also a cause of shredding thread).
Set the upper tension at the midway point perhaps a bit looser for FMQ (this tension will probably need to be tweaked for your particular machine due to wear and age).
Use an FMQ foot and drop the feed dogs. A Supreme Slider (avlb on the internet) is very helpful in helping move the quilt while doing FMQ.
Work at a moderate but steady pace. I find a faster speed while FMQ gets me into trouble...like spots I can't get out of, overlapping stitches, or outside the quilt edge.

FWIW, I still get some skipped stitches with FMQ. Usually, it happens when I move the fabric too fast, especially around a curve. I have a tendency of speeding up while going around a curve that will cause skipped stitches or eyelashing.

I'm also wondering if there is something to do with the fabric and/or batting you are using...like is it Batik? Batik is very tightly woven and presents some particular challenges. The type of batting could be more dense, making it harder for the needle to penetrate the sandwich. Also, pulling or stretching the fabric can cause skipped stitches.

Juki ddl8700 shreds the thread


Thread shredding:

Install brand new needle(s). Make sure the needle eye is the appropriate size for the thread you are using. Check that the needle is the correct type for the fabric & thread, ie coarse (abrasive) fabric would benefit from the protection of a top stitch needle which has a larger scarf.

Sometimes the thread is being held back in the thread path causing the needle to wear and shred the thread. Check that the upper tension is correct. ALWAYS RAISE the presser foot when threading the top thread. Make sure the upper thread follows the correct path and that it is not threaded incorrectly or looped around the spool pin or a thread guide.

Juki sewing machine keeps sewing after releasing foot pedal


Your machine could be out of time. When you turn on does it stop or stitch a couple switches. Belt could be worn out as well. How old is it? Thank you very much. Please leave some feedback or more information so I may help you.
