On a brother LX-3125 when you sew an item then remove it the bobbin thread has bunched up alot of thread comin out

SOURCE: thread bunching up under fabric.

Be sure that the thread is in the TAKE-UP lever. There are four thead guide the thread must pass through. From the spool through the first thread guide at #1 than straight down to #2 than up to #3 throught the take-up lever and straight down to the left of the needle and throught hte neele form fornt ot back.

If the thread is not in that take-up lever the machine will not have any top tension (or be regulated) it will flood the machine with thread and wrap around that bobbin.

Also, be sure have you presser foot int he up position while threading this way the thread will surely pass through the tension disks, Set your top tension at 4, use good quality thread (get rid of the dual duty or all purpose) All of these steps will ensure a perfect balanced stitch.

You should hold the end of the thread coming through the needle until the thread has grasped the bobbin thread.

Mine did the same thing. The needle is probably to high. Do not insert the needle all the way to the top. Lower it a bit and it should zig zag!

Have you had the machine serviced since you purchased it? This is something that should be done at least once a year.

Take the machine to a certified Singer dealer and explain what is happening. There may or may not be something that needs to be adjusted.

Your warranty is still in effect, but is now limited. Attempting to repair it yourself or having someone who is not a Singer dealer repair it will invalidate the remaining warranty.

Is there thread caught in the bobbin case? How far are you turning the wheel and are you holding the end of your bobbin thread out so that the top thread can hook it?
