New Home MyLock 234 Stitches Jamming

Put a new needle in left position. Following directions, threaded all four positions. Now the stitches are creating a nested knot. It is getting jammed on the hooking arm and underneath the needles. I tried rethreading and pulling all threads to the left (11:00 position) and manually making stitches and it still nests up in knots.

SOURCE: my white speedylock serger 1634 thread keeps getting in knots

i have the book and it says thread from inside out, inside looper (upper) then lower, then thread the needles, first right then left.  I have found that it does not matter if you thread the needles or loopers first but that you should try to thread from inside to out.

SOURCE: the thresd gets knotted and it won't stitch

Rethread your machine
Make sure your cotton runs through the two tension plates
Check that your top tension is set on 5
Make sure your bobbin case is threaded correctly
Lastly, make sure there is no cotton stuck between your top tension's plates(take a long needle and remove any fluff)

SOURCE: skipping stitches and knotting up underneath.

Hello,
Here are a few things to try.

* Raise your feed dogs if your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.



* Your fabric may require a different needle. Generally, heavier fabrics require larger needles and thinner fabrics, smaller needles. You may also need a larger needle if you’re sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for woven (or a universal needle for either). And make sure your needle is appropriate for the type of thread you’re using.


* Adjust the pressure of your pressure foot, it may be too light for your fabric.


* If your upper thread and bobbin threads are different types, try using the same thread for both. And use a good quality, brand name thread.



* Change your needle plate. Try switching to a needle plate with a smaller hole (a straight stitch needle plate).


Important Note: If you change your needle plate, check to make sure your needle aligns perfectly with this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which could be dangerous. And make sure to change your needle plate back for zigzag and other wide stitches.

Hope this helps.

You can go here, search 5525, and download or purchase an instruction manual for your machine, if you have misplaced the one that came with it. It looks like there are some available as downloadable pdfs for free and some physical ones for $15. https://www.singerco.com/accessories/manuals.html

Also, Singer has just installed new Q&A features on their website. You can go here: http://new.singerco.com/products and look for your particular model or machine category. At the bottom of the product page, you can post Questions for singer experts and other community members to answer!

Good luck!

Machine dropping stitches


Skipped stitches
1. A bent or dull needle
2. The wrong needle for your fabric
knit fabrics require a jersey or ballpoint tip. Most wovens do well with a universal tip, and specialty fibers, like leather or metallic, usually require specific needles.
3. Incorrect machine threading
4. Unbalanced needle thread tension
Start by making relatively small changes and run a test stitch to evaluate the impact. If you need to adjust the tension dial using woven cotton fabric with good quality all-purpose thread and a new needle
5.check the needle is inserted correctly. The needle needs to be pushed as far up the needle shaft as possible. It's easy to insert the needle half way, clamp it down and think it is inserted correctly.
the flat part of the needle should be positioned towards the back. If the needle is not inserted correctly, it will not be able to pull up the bobbin thread and will cause skipped stitches.
6. If the suggestions don't help then it is time for a tune-up.

How do i check if the timing is correct


Put in a new needle. Thread machine with same thread top and bottom. Set upper tension to default (4/5 usually) and sew in straight stitch with needle in default position (usually centre) some times left. Turn hadwheel by hand towards you for the first two stitches to ensure needle not hitting hook or driver. If machine sews find, then try the zig zag. If both these are good, timing is good. If not, and stitches are skipping or not forming, it could be a timing issue and you should take it to a tech

Singer ce100 is skipping stitches when needle is in center position


You don't say what you are sewing so I'm going to give you general answers in hopes it helps.

1. Needles: There is no such thing as a universal needle. Make sure you are using the proper needle for your fabric. This goes for thread too... make sure it's sized for the needle.

2. Make sure the bobbin is threaded correctly (poorly wound bobbins will cause problems too)

3 Improperly threaded machine. Make sure you area threading it correctly with the foot in the UP position.

4. If you are a material puller... shop it. It is never good to pull your fabric through the machine as you sew.

5. Stitch length. simple rule: Fat fabric.. long stitch, fine/thin fabric short stitch.

I'm not familiar with your futura abut I've noticed new home machines take a way presser foot pressure adjustments... which can cause issues too.

Tension to loose and missing stitches


SKIPPED STITCHES ON A SERGER
1. Is the needle bent or worn--replace
2. Is the needle inserted correctly into the needle holder--check needle
3. Is the Serger threaded correctly--rethread
4. Is the presser foot pressure right for the fabric--adjust

use a scrap piece of fabric to sew on as you adjust the tension
when the tension is to loose adjust one number higher till stitch
looks good

here's 2 links for a manual one is a hardcopy & the other is a
pdf downloadable--one is a different price from the other

Have a brand new Singer 1507 that keeps jamming the bobbin thread. Have followed threading and winding bobbin instructions closely, but am still having problems with the bobbin thread jamming after 1-2...


I would try adjusting the tension on the machine - this sometimes causes the bobbin thread to jam while sewing. Re thread the entire machine including the top thread. Also it is recommended to use new thread as old thread can ball up after time. If no luck I would call the store you purchased the machine from.

Pfaff 7530/ electronic problem?


Where has it been for ten years? This could have a big affect on an electronic sewing machine.

Take the machine in to a sewing machine shop for service.

Mylock 634D looping left needle stitches


Make sure the thread is in the tension disks. Do this by pulling the thread backwards towards the spools. Also set the tension on zero and check for any fluff, or thread that is stuck in the disks, preventing them from closing properly. Good luck
