I do not have a problem sewing regular stitches. when i try to do the free motion quilting my thread keeps shreading and breaking.. sometimes it will sew for 12 to 15 inches before it breaks.. i have changed the needle and the tension and the bobbin tension but still no luck.. so frustrated with the machine now.... it seems that the upper tension is too tight but i loosen it and cant get a good stitch... when the feed dogs are down the machine will not sew. please help. i have worked with it for 2 days unsuccessfully. could you tell me what needle i need to use what thread and where should my tension be set on the top and how tight on the bottom... the book says the bobbin should be the same as the top but if i do that the thread is too tight.. It is probly me but i can get the machine to sew wonderfully if i want to sew straight sewing..this is 1500 s brother..... iva I am haveing the same problem, top thread gets shredded and breaks or the thread on the back looks a tarantula. This machine worked great for the first two projects and now I can't get it to quilt at all. I have changed the needle, adjusted both the top and bobbin tension, cleaned the machine and tightened all the screws!! Can someone please help!?? My brother 1500S will quilt for about 18" and then the thread shreds and breaks. I've changed type of thread, needle and tension on my fabric but to no avail.....any suggestions????
If the thread is shredding and breaking, there is an incompatibility of your needle, thread, and fabric. Could be old, bargain bin, or poor quality thread--does the thread have little "hairs" of thread lint sticking out of it--that's probably not good quality. Look for fresh, good quality thread. Try a brand new needle--a sharp if you are sewing woven fabric. Make sure the thread is not too big for the needle eye. Sometimes, a top-stitch needle or embroidery needle will work well on FMQ. (A top-stitch needle has a longer scarf which helps protect the thread during the multiple times the needle penetrates the fabric before the thread forms a stitch. Shredding means the thread is getting worn out before it forms a stitch. A piece of thread penetrates the fabric 10-20 times before it forms a stitch.) Could also be a snag somewhere that is damaging the thread.

Most FMQ instructions say the upper and bobbin tension should be the same, however, I find my machine works a bit better when the bobbin thread is just a little tighter than the upper thread. Then the bobbin thread does not "pop" up on the top of my fabric quite as much. It's probably something you will just need to experiment with in getting used to your machine.
P.S.--when threading your machine, make sure the Presser Foot is ALWAYS RAISED so the top thread will seat properly in the tension disk. Failure to do this will cause thread barfs (usually referred to as thread nests or bird nests) under your fabric. Also, before beginning your FMQ, ALWAYS PULL the bobbin thread to the top of the fabric, then hold both thread tails gently in your left hand while you slowly take the first couple of stitches.

Are you using the right needles, size and type? Before, you wreck your material, take it in and have it serviced. I know everyone hates to pay for service, but if you like your machine it will be worth it to have it running at its peak. Just like a car, we spend tons on them but expect a sewing machine to never need anything. Remember, it is worth it.

change the needle
rethread the machine
some needles & thread are not compatable-try this
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread
check to make sure there are no burrs on any of the thread guides
try a 3 or 4 top thread tension

a sewing machine I work on last week, I put a new needle in the needle clamp & thought I had it correctly inserted,, but it wouldn't work,, so I went back & checked the needle again & found I had to unscrew the needle clamp screw even more than normal to insert the needle then it work perfectly.
some needles & thread don't work togeather--here's a tip
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle

also clean under the needle plate where the feed dogs are for lint
& also in the bobbin area for lint & loose threads

this is a known issue with the pfaff.....i have just bought the machine and it has thread uptake issues...thread tension issues and it comes unthreaded by itself often...leaving globs of thread on the bottom stuck in the feed dogs and under the throat plate.....then the stitches are not properly balanced because the tension gets too loose on the bobbin thread....very disappointed to find out it is a known issue with all the viking husqvarna made machines...which are pfaff, janome and viking.....sux.
