The tension for embroidery is way off. The only thread visible is the bobbin thread. The top thread is almost invisible. Straight stitching tension is not perfect but OK

It sounds like the thread did not stay in the bobbin tension slot correctly. Try putting the bobbin in again and sure you have a suitable bobbin thread. If that does not work then a new bobbin case is what you probably need.

Bernina 780 sews great, but thread in bobbin keeps messing up while doing embroidery,


Usually, if the thread is messing up under the fabric, it is a top thread issue. This is sometimes referred to as thread nesting or bird nesting.

Make sure you are using a brand new needle of the type specifically for embroidery. The eye needs to be large enough to easily accommodate the thread size and it needs to be a sharp needle. It may help to use a needle with a larger scarf that will protect the upper thread when piercing the fabric. If the thread is not protected sometimes it will hang up on the underside of the fabric when the needle withdraws from the fabric, causing thread loops, etc.

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. (This releases the tension disk so the thread seats completely.) Verify the thread path is correct.

Use a bobbin thread that is compatible with the embroidery thread. Check that the bobbin thread is smoothly wound on the bobbin, that the bobbin is turning the correct direction in the bobbin case, and the bobbin case tension is threaded properly.

Retest your embroidery on a small project. If you are still seeing thread bunching up under the fabric, you need to tighten the upper tension.

I have a Bernina 145 S activa and I can't get my satin stitch to work , it brings the bobbin thread to the top , what can I do ?


Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.

It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)

How to adjust the bobbin tension.


According to the manual, you should not need to adjust the bobbin tension (and I located other sites which stated the bobbin tension cannot be adjusted on this machine). Apparently, all the tension adjustment is accomplished through the upper thread::
"EN Thread Tension Upper thread tension Basic thread tension setting: "4". (1) To increase the tension, turn the dial to the next number up. To reduce the tension, turn the dial to the next number down. A. Normal thread tension for straight stitch sewing. B. Thread tension too loose for straight stitch sewing. Turn dial to higher number. C. Thread tension too tight for straight stitch sewing. Turn dial to lower number. D. Normal thread tension for zig zag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric. Lower thread tension The bobbin tension has been set correctly at the factory, so you do not need to adjust it. Please note: - Proper tension setting is important for strong seams. - There is no single tension setting appropriate for all stitch functions, thread or fabric. - A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing. - 90% of all sewing will be between "3" and "5". - For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing. - For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric. 1 A B C 22 D"

Doing further research, I found this statement on a machine review site:
"After reading reviews online from where I've bought my drop-in bobbin machines, I think many of the negative reviews are due to the bobbin thread coming up without laying across the bobbin. It can cause the stitches to look very sloppy and no amount of tension adjusting can fix the stitches."

There are several machine review sites wherein 4423 owners stated their disappointment in the 4423's performance. Some said the machine failed almost immediately and others said the machines developed problems when sewing heavy fabric.

Bottom thread is still loose even if i try to balance the tension, how do i balance the thread tension?


You bobbin tension CAN be adjusted. First, thread your machine with different colors in the top and bobbin, set your top tension at its default, and run a line of straight, and then a line of zigzag stitches, and compare the results at the top and bottom. You will be adjusting your bobbin to your top tension. If the top tension looks like a straight line instead of stitching and the zigzag looks like "chicken tracks" instead of a zigzag, but the bottom looks like a zigzag, your bobbin tension is too loose.

Remove the bobbin case, and locate the straight-slot screw. There are generally two; one is a Phillips and one is straight--you want the straight one. Leave the other alone.

The rule is "lefty-loosy, righty-tighty." If your stitching displays the above symptoms, it needs to be tightened, so turn 1/4 turn to the right--no more--then test again. You will need patience, but don't turn more than that. It is easy to do, but if you don't do it systematically, you can make things worse, and very slight adjustments can alter the stitching significantly.

Singer xl-400 bobbin tread to loose when momograming


It means that your top thread tension is tighter than your bottom thread, and it's pulling your bobbin thread up. You loosen your top thread by turning the dial towards the "S." You should only have to loosen it by a maximum of one number; if it's more than that, you may have to adjust the bobbin thread tension.

You do that by first turning off the machine and removing the embroidery unit. Turn the tension dial to S. It helps to use a different color top and bottom thread, with the scrap fabric a third color. Run a straight stitch and zigzag stitch and examine them. If one size of the zigzag looks like "chicken tracks" or one side of the straight stitch is a straight line, it means that side is too tight. Take a look at your user's manual on page 11. If your top tension is on "S" and it is the side that is too tight, you will need to tighten the bobbin tension, to match the top tension. Tensions are a BALANCE.

The next step needs to be done systematically and carefully. If you don't, you can really make things worse. Set your mind to doing everything step by step--don't get tempted to jump ahead. Take the needle plate off and take out the bobbin case, and locate two screws on the side. One is a Phillips screw--leave it alone. The other is a straight screw--that's the one, and you will need a tiny screwdriver to adjust it.

The rule is "righty-tighty, lefty-loosey." Remember, you are trying to match the top tension! Give the screw on the case no more than 1/4 turn, reinsert and retest. You should see at least a little improvement. Keep doing that until you have balanced your stitches, and DON'T jump ahead! The difference between too tight or too lose is often a very small turn of that screw--especially when you're close.

Embroidery not working correctly


Well, before I did all that (which may be necessary), I would take a piece of UNWAXED dental floss or hand embroidery floss and floss between the tension disks. You mentioned that you were suddenly breaking threads; there may be lint or loose threads or both seated between the disks, preventing the thread from seating properly. Then,
I would take the embroidery unit off and try to do some sewing with it, to see what results I got. If you can catch and bring the bobbin thread to the top with the top thread, I am doubtful that your timing is off. Sew a line of both straight stitch and zigzag stitches, and see if the stitches are balanced. If not, you may have a bobbin tension issue, and if so, most bobbin cases can be adjusted.

I think you'll find, though, that things will improve considerably when you have cleaned out the upper thread path and tension disks. Make sure when you do that, that your foot is raised, so that the disks are spread. Oh, a drop of sewing machine oil wouldn't hurt either--generally you should put a drop of oil for every 5 hours of embroidery.

When I embroider with my Pfaff Creative 2 the top tension pulls bobbin thread up too much. I changed toe tension on top but it still does the same thing. How can this be fixed?


Suggest you do rethreading ,then test the stitches on straight stitch. If top stitches is loose you have to reduce the upper thread tension, if the bottom stitches is loose you have to increase the upper thread tension. Adjust accordingly till you can get a perfect straight stitch. If okay then you can continue your embroidery work.

I have a singer futura xl-400 and I am having a problem with the machine


It sounds to me like your bobbin tension is off. Take the embroidery unit off and set the upper tension to "S". Run a line of straight stitches, then a line of zigzag stitches. It is helpful if the bobbin thread and the top thread are different colors for this. If the top thread is almost a straight line, your bobbin tension is too loose. If your bobbin tension is almost a straight line, your bobbin tension is too tight.

To adjust the bobbin tension, take the bobbin case out and locate two screws on the side. The one you want is the straight-slot screw on the left; leave the Phillips on the right alone. The rule is "lefty-loosy", "righty-tighty" turn in the correct direction only 1/4 turn and sew another line; you should see SOME improvement, but it may take repeated attempts to get it in balance. When it is, put the unit back on, and don't forget to change the upper tension to "E".
