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 MO-634DE Stiching


I tried to find this on the Juki website but its obviously a previous model so not much info on there. But did find it listed elsewhere as a 3/4 thread overlocker.

So I'd guess at the following, it probably seams a four thread marrow (overlock seam) made with two needles and two loopers. And a three thread overlock seam where you use either the left or right needle, this would give you either a narrow or wider 3 thread seam. Image below of 3 and 4 thread overlock seams.

Lastly, I would suggest that the D denotes Differential feed, this is a feature that controls the two feed dogs in the machine and gives you the ability to set them to move at different speeds - very handy to control the fabric feeding but also used decoratively for lettuce edging.

Rolled hem - most overlockers of 3/4 variety will also do a rolled hem; however, I can't actually confirm if this model does or not. But look around for a retractable stitch ****** in the foot or needle plate or a second needle plate in the accessory case. Rolled hemming is also very useful and most models will do it now; just variation in how you actually set it up to do so. Bernettes you flick a lever in front of the needle/foot area, earlier Elnas like the L3 and L4 you needed to change the needle plate and a little ****** in the presser foot.

Of course, you could email the local distributor for Juki in your country and ask them and this may be the best way to check. Just copy this into your browser

I am having problems with my Juki TL98E skipping stitches when I free-motion quilt. I have cleaned it well, put in a new needle but still having problems. When I stitch forward, it's ok, but when I try to...


It is a timing issue. I have a TL98E. The needle bends a bit when free motion quilting, moving the needle away from the hook, thus missing the thread. Try to put in a larger needle, or have the timing changed so that the hook "kisses" the size needle that you want to use. Tammy

Free motion quilting skipped stitches, breaking threads


Might be that you need to lower the tensions quite a bit, you'll have to juggle with top and bottom tensions though, and experiment for just this operation with the Sensormatic.

The needle thread on my bernina minimatic keeps breaking.


There is special thread for denim/jeans. It usually comes in shades of brown. It's a little heavier and might help with the breakage. You might also want to try a little less tension. I assume you already have a Schmetz denim needle?

Needle Thread breaking after about 30 seconds of quilting


Make sure the feed dogs are dropped (or feed dog cover is on - I can't remember which way this machine works). The stitch length on the machine has no function so ignore it. (I set it to zero so the machine doesn't have to work as hard). Hopefully this is all that's wrong. If not, use a shorter setting for the stitch length on the regulator, oil the hook and move slowly and smoothly.
Good luck!

Needle thread breaks while quilting on machine frame


My friend and I both have the Juki 98Q but on different frames - we were both having problems (needles breaking, thread getting tangled) we removed the thin metal thing inside the bobbin case and have had no problems since (over a year now!).

Coverstitching on White Speedylock serger


Your machine cannot do a cover stitch. Check the Brother website, they make a cover stitch only machine, it works much better than any of the serger/cover stitch combination machines, and it is a lot less money.
