I have the Brother ls2125i and LOVE the machine...in the middle of sewing, it started making very big loops on the bottom stitch and they do not catch the thread from the needle. Is it the tension?...
Here are some things to try:
Big loops are actually easier to solve usually. 1st know this: Loops on bottom means the top is too loose or the bottom is too tight. With loops that big its probably the top is too loose. 1st look in tension disks, there is likely a chunk of thread in there. A toothpick is handy to dig it out (the flat kind) 2nd make sure that the thread is getting between the disks when threaded. 3rd Make sure the thread is in the take up lever (the thing that moves up and down in front and not the needle bar or any part of the needle bar.) If neither, then the bobbin case could have a burr on it and the thread is hanging on that burr. Also the bobbin case may be in wrong. I hope this helps
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on top and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no matter how much thread you pull, your thread is good. If that your machine passes that test, we can go to step 2. If not, try different spool of thread, do the same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
