I bought a new Juki long arm to use on my Little Gracie Quilt Frame. Just about to finish and the top thread keeps breaking! So frustrated! Any suggestions?

    Hello Duckee;

    I'm hoping that by now, your problem has been resolved. I do have a few ideas, though I feel inadequate to make any suggestions as I am brand new here.

    First, take a deep breath and see if you can determine 'where' the thread is having a problem. Check to see if there is anything else going on, like bunched threads on the underside of fabric, bobbin jamming, etc.

    Now that you have a pretty good idea of what is happening, pull out your manual and go to the troubleshooting pages. No one knows your machine better than it's maker.
    If after checking everything in your manual, you still have the thread breakage problem, here are a few more ideas, that some of the manuals don't mention anymore, but us old folks still know about.

    I often have threads break when I don't change my needle frequently enough - between the needle getting 'dull' and the wear of the thread in the needle's groove, it usually causes me to look there first.

    Of course there is also the the type of needle &/or thread. Sometimes I forget that the thread or the needle that I was using on my last project is not the one I should be using on this one. Check the thread and the needle to make sure you have what you need. It's pretty easy to get a 30 weight thread mixed with a 40 weight, etc.

    Tension adjustments are often the cause of broken threads. Using your manual check your tension. there was a time when I could have told you exactly how to do that on your machine, but these days I am lucky to know my own machine, and even then I still need the manual. LOL

    Check the bobbin compartment for built up thread lint. If you see any, remove it as gently as possible. I use a turkey baster to blow the lint out or a skewer to dig it out. Choose your weapon wisely for the task at hand.

    I know most of the newer machine don't need to be oiled, but the older models still do. If you have an older model you can be pretty sure it needs to be oiled. Check your manual for instructions, and follow them very carefully. If your machine does need to be oiled, a good rule of thumb is to do so somewhere around every 12 - 20 hours of use.

    Last but not least, you might want to consider that the spool of thread you are using is malfunctioning. I used to work at a spinning mill where we made thread, and a LOT of spools had to be refilled because they were found to be defective. A while back I had a spool of thread that the entire middle section of the spool was funky (looked like it had spurs coming off of it when I placed it under a microscope), then I got past that section, and it was fine.

    Well, I hope this helped, or maybe gave you some ideas, or just made you laugh a little (I AM a little anal retentive- who else would bother to check their thread under a microscope, or pull off all the thread until the funky stuff was no longer an issue? These days, most people would have just tossed it into the garbage, But like my name implies I am an old girl, brought up by the old rules, and I do things the old way. - Most of the time ;-)

    Thanks for all your suggestions/help/ideas! I have been reading and reading for ideas. My machine is brand new! It worked fine (after getting tension set) I was almost finished with my quilt when this breakage started! I was checking the thread out and it seemed to me it broke too easily when I pulled on it so I am going to check it out more carefully. I also went to the quilt shop in town and they suggested getting a bigger needle (which did not help) I am determined to figure this out today! Wish me luck!

    What size of thread are you using and how tight is your tension. There are three things to consider; needle size, thread delivery and tension. I'll be happy to help you.

    THanks so much. After spending pretty much the whole weekend on this I finally went and bought new thread! So far, so good! Geez, wish I had done that sooner! Really appreciate your response! I am going to love this site!~
