My experiences with thread breaking with machine on a quilting frame make me look at the upper tension being set too high, the needle being worn or movement of the machine is too fast. Reduce the upper tension first, then sew in straight lines at first. See if you can sew slowly, in straight lines and reduce the upper tension until the thread stops breaking. If so, try some 1-2 inch circles, again going slowly. If the needle thread is pulling to the back, you will need to increase the upper tension again until the stitches meet in the middle of the fabric. If you can't locate a balanced spot where the needle thread is not pulling to the back side and thread doesn't break, try taking the machine off of the frame and sewing on a table. If it won't sew this way, it needs some professional help. If it does, you will probably save a lot of time taking it in for service, making sure to explain to the repair center that you have problems on a quilting frame, not while sewing normally. When the machine is adjusted to sew normally on a table and you move it to the frame, you will probably need to reduce the tension by 1-2 complete turns of the tension knob.

Hello,

A feed system for a sewing machine having a frame, a horizontal arm shaft journalled in said frame, a vertical arm shaft extending downwardly from adjacent said horizontal arm shaft, means rotatably connecting said horizontal arm shaft to said vertical arm shaft, said feed system comprising a cam fixed to said horizontal arm shaft, a sheet metal feed fork having parallel bent over portions at one end thereof embracing said cam and in driving engagement therewith, a feed rock shaft supported in said frame and having an arm connected to the other end of said feed fork, feed regulating means carried by said frame and connected to said feed fork for converting motion induced by said feed cam to oscillations of said rock shaft, said rock shaft being formed with a pair of upright rock arms on the other end thereof, a horizontally disposed U-shaped sheet metal feed dog carrier having each end thereof connected to one of said upright rock arms, said feed dog carrier having a horizontal shelf extending from the base of the U between the ends thereof, said shelf supporting thereon a feed dog, means for attaching said feed dog to said shelf, a stud affixed to said base of said feed dog carrier beneath said shelf, a sheet metal lift lever pivotally supported on a horizontal axis in said frame substantially parallel to said rock shaft, said lift lever having a slotted end for engagement with said stud extending from said feed dog carrier, said lift lever having the other end thereof supporting a cam follower adjacent said vertical cam shaft, and a lift cam removably affixed to said vertical cam shaft and in engagement with said cam follower on said lift lever.

Take care.

My friend just had this problem a couple weeks ago. Here's what we did. We cleaned the bobbin case with canned air lightly. We turned the machine off and disconnected the embroidery unit. Turned the machine on without the embroidery unit and ran a straight stitch. Then we turned it off, reattached the embroidery unit and touched another design of a different size. Attached the hoop without fabric just to see if it would "take it" and it did so we put the right size hoop back on and selected the design we were on originally and it worked. Some times these machines are just "touchy" and don't let you do something and after a "rest" they're ok. I hope this works for you.

Depending on your model of machine this problem is solved by replacing the hoop attachment unit on the hooping arm. (hoop sensor cable is not properly welded)

There are two key points I suggest customers can do themselves to help lengthen the life of their machine. One is your hook and the other is the needle bar...
Hook - Open your bobbin door, removee the bobbin case/bobbin. On the upper left corner there is a small latch, push in the latch and your shuttle race ring will fall down forward. You can now remove your stainless steel hook. You need to keep this hook clean and the lip it fits back into clean and void of lint and debris. On the back of this hook or the "lip" that the hook fits back into apply a small amount of hook/sewing machine oil.
Needle Bar - Open up your head cover, the needle and needle bar clamp is attached to a long stainless steel rod that travels vertically inside your head. All sewing machines have a needle bar that looks like this. This bar travels thru two brackets attached to the frame of the machine. Rotate your handwheel and clean the needle bar well of debris. Rotate the handwheel so that the needlebar is in it's highest point and apply a small amount of oil to the upper and lower bracket of the frame, rotate the handwheel so the needlebar slides back down and therefore lubricating it and the inside of the brackets.
Hook oil or sewing machine oil is relatively inexpensive from all quilt, sewing machine, repair shops. Be sure to take your machine in a minimum of every three years for proper cleaning and lubricating of all the other parts (This is of course for average home sewing machine use 8hours a week)

It is most likely the feed dog return spring. A cam lifts the feed dogs up and the spring pulls them back down. It hooks to the feed dogs bracket and goes straight down to the machine frame, there should be a small hook or post for it. You may be able to sew slowly without it attached.
good luck!

The solution is to take it to an authorized Brother dealer. It sounds like either something wrong with your embroidery hoop sensors, or more likely something is wrong with the brain of your sewing machine. Hopefully after all this time you've done just that. I'd hate to think of a ULT just sitting around collecting dust.
