Maybe, if I kne4w what FMO meant. As far as top tention breaking, generally thats because of the runs that the thread goes through.
This may help:
Thread Breakage
There are three common reasons for your thread to break on you;
A. Stress Break
B. Clean Break
C. Hook Break
Stress Break
Stress breakage occurs when your thread is snagged and can not be pulled as you quilt. There can be several reasons for this;
a. Thread unwinding unevenly from the spool causing it to wrap around something on the machine.
b. Thread snagging on one of the thread guide.
c. Top tension set to high.
d. Thread is old
Whichever the reason, you can generally tell a how a thread has been broken by looking at it. The figure to the right illustrates a stress breakage.
Clean Break
Clean cuts generally occur most often when cut by a burr. A burr is a sharp edge that has been caused by the needle striking another metal object. The thread looks as if it has been cut by scissors. The figure to the right illustrates this type of breakage.
Hook Break
A hook breakage is fairly easy to determine. Generally a few fibers will be hanging to the side while another group of fibers are bunched up a little higher on the thread. The figure to the right illustrates this type of breakage. This occurs most often when your timing is off. The hook may be too far from the thread when it tries to grab it, and only catches the outside fibers. A burr on your hook point can also causes this to occur.
Some fixes for the breakages above include placing small scraps of batting in the thread guides to maintain thread travel. Always use all of your thread guides when quilting, but don’t add new ones.
Remember that the proper tension is set by the machine being threaded correctly. Some people have purchased added gadgets to set their tension, that’s usually not needed if you follow the manufacturer’s guidelines.
Hope that this helps,
