My ls2125i won't stitch

Whenever I start to sew, the thread just jumps out of the needle. If it does start, there are no stitches on the fabric or there's a bulge of thread on the underside of the fabric. I need help please. It is a fairly new machine. Thanks

Start slowly, make sure your thread trails are long enough, I had this problem a LOT when I first started using this machine. (mainly because it was my first machine!)

Fabric bulge- Don't try to push the fabric through the machine, let the feed dogs do it. Your job is to guide the fabric.

Thread jumps- Also, like Outdoorsman said, the tension is probably off. On this machine, the tension knob is easy to find. It's the small one with the numbers on it. "0 1 2 3 4-5-6 7 8 9" 4-5-6 are your optimal sewing tensions. I usually sew on 4 or 5, depending on my fabric and type of stitch.

No stitches- Your lower thread may not be being grabbed properly/bobbin case may be jumping out of position. Open the lower case and make sure your bobbin case is secure, and the thread is grabbed properly.

Hope this helps!

Although I am not a expert at sewing machines, I have worked a lot with an industrial sewing machine. You might check the tension of the thread that goes through the needle. If it is to tight it will pull it through the needle. There should be somewhere on your machine that you can adjust the tension.

What is the factory tension setting for the Brother LS-2125i sewing machine?


you probably wont find it listed anywhere as it is from experience and changes with different material thickness and needle size
SO how to set tension
thread the machine and adjust the tension until you feel a drag on the thread
now thread the needle and sew a piece of scrap material
if the thread bunches up underneath then increase the thread tension until it sews properly
if the bottom thread is pulled to the top or the thread keeps breaking loosen ti off a bit
when the stitch is being properly formed , both bottom and top threads should meet at the center of the two materials being sewn

Skipping 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.

Skipped stitches. Also, won't transition


have you checked the needle to make sure it's in correctly--flat side of needle goes to the back of the machine

correct needle insertion is mandatory for the proper use in your sewing machine. Raise the needle bar to the highest point, then loosen the needle clamp screw to remove the old needle.
place the new needle in the needle clamp with the flat side of the needle facing the back (or if using a round needle the groove in the needle should be facing away from the shaft.
push the needle all the way up to the stop, or as far as it will go, then tighten the needle clamp screw.

how to decide which needle is correct to sew with, it depends on the fabric & thread being used for the project.
like for example, I've been sewing for over 30 years, I'm sewing a stretchy fabric & regular needles won't work because they skip stitches & will pull the fabric thus damaging the fabric, the needle I have to use is a singer universal ball point needles, & I have no problem with the stitches they come out fine.

Skipping stitches and upper thread breaking on JCPenney 6600


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.

I hope this helps.

Whenever I zig zag my machine skips stitches.


Hello,
Try these solutions.

* Re-thread your needle
It may be threaded incorrectly (backwards).

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly – usually with the
flat side away from the bobbin, but consult your machine’s manual to be sure.

*Change your needle
Your needle may be blunt, bent, or otherwise damaged.

*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 wovens (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.

* Change your thread
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.

* Adjust your thread tension
It may be too tight or too loose.

* Re-thread your machine
It may be threaded incorrectly.

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

Important: 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.
I hope this helps you.

Viking Designer 1 balleds / Birdnest / issues after repaired from Husk service center in midwest - replaced thread needle and adjusted tension .. freequilting and embroidery situations


birdsnest refers to a mess of thread on the underside of fabric when you start sewing (after a few stitches all looks good). if this is the case and it is happening during embroidery, switch off jump stitch thread cutting.

if it happens at the start of normal sewing, either hold your needle thread when you start sewing or make sure the needle thread is under the presser foot and held by the presser foot when you start sewing. this way you will have an inch or so of thread on top of your fabric which you can trim instead of a mess underneath.

if there is a mess underneath for more than first few stitches, either your check spring in the needle tension area is set incorrectly, or your needle tension is set too loose (adjustable in sevice menu by tech only) or there is foreign matter caught in tension assembly preventing proper tension.

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing direction...do not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the needle...do it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.
