SOURCE: top tension is making a loop as I sew, bottom

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.

The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

SOURCE: do i need to oil my baby lock sewing machine?? Quiter's choice.

I cannot find a manual for this machine except at sew4less.com and the price is $14.95.

Contact Babylock to see if they will provide you with a download of the manual - http://www.babylock.com/contact-us/index.asp

If this is a mechanical machine, use sewing machine oil and the shuttle may be the only place it will need to be oil.

SOURCE: how do i set the tension on my brother xl-3010

I don't have this machine, but the tension on the bobbin is usually set by the tiny screw on the bobbin case. insert the bobbin into the case so that the thread unrolls counter clockwise. Make sure that there is no lint in the bobbin area.

I am having issues with the top tension Crown Jewel. It sews with the top thread flat. I have adjusted the top tension down and it is still flat. Adjusted bobbin and cleaned. Any suggestions?


You need to tighten the bobbin tension. Be careful! A little at a time and be sure to mark the setting BEFORE making any changes so you have a way to backtrack.

I'm having serious issues with my new bobbin wonder that came with my baby lock crown jewel 3. Once it does start winding it winds on one side only.


That could be a matter of adjusting the bobbin winder position (possibly a service repair). Most machines I have tend to wind more on one side than the other. I just use a stiletto or even a pencil to move the thread up or down during the winding process to help balance it on the bobbin.

I hav a baby lock modelbl3-437 ive thread it correctly n the tension but it still doesn't make a stitch


You most likely did thread it correctly. Try to thread it with the foot up and give little tugs while doing it. If it snags there is a problem. If the tension isn't set properly there will be problems with sewing. Try to start by setting the top tension at four. Look at the attachment to follow some rules to set the bobbin tension.

What would cause by screen to go dark on my baby long crown jewell


Could be many things, I would check the Power supply on the left of the machine when you stand in front of it. Turn off power first, then remove 4 screws power supply will come straight off. look at attached wires and make sure all are attached firmly. If that does not fix it, take it to a service man.

Pfaff long arm really long loose stitches on


You need to get the tensions set correctly, sounds like either you have not gone through the tension discs or the top tension is too loose.

Proper Settings


A good standard tension setting is usually around 4.5.
If you find it to be looping on the bottom, raise your top tension. If it's pulling bobbing thread to the top, lower your top tension.
For straight stitch, your stitch width should be set to zero, although on some machines (and I believe your Baby Lock to be one of them,) the stitch width setting will change your needle position.
Stitch length is simply a matter of preference.
