You might also try pulling the bobbin thread to the top of your fabric before beginning to sew. Here's a helpful video:

Soulds like you did not get the upper thread in the tension unit when you threaded it. Try this, thread your machine all the way to the needle but not in the needle eye. After you do this lift the presser foot up and down, you should have tension with the presser foot down and no tension when it is up. If this is not the case your machine is out if adjusment.
Hope this helps

My thread bunches under me material and can' t sew

Sounds like "thread nesting" also called "bird nesting." Usually, it is a result of incorrect threading, incorrect tension, or the thread not being properly seated in the tension disk.

Remove the thread.
Install a brand new needle.
RAISE the presser foot and rethread the machine from the beginning making sure the thread path is correct.
Set the upper tension to the midway point between low & high numbers.
The correct tension is achieved when the upper and bobbin threads meet in the middle of the fabric. If upper thread is looping under the fabric, the upper tension is too loose. If the bobbin thread is appearing on the top of the fabric, the upper tension is too tight. If it is difficult to determine what is happening with tension, try using a different color thread (but ALWAYS the same type & weight) in the bobbin as what is used as upper thread.

Tension is static--it needs to be adjusted whenever a new project is begun because the needle/thread/fabric combination will affect the tension. A sewist should become comfortable with adjusting the upper tension on a piece of the scrap fabric before actually beginning to sew the project.

The needle/thread/fabric need to be compatible to get the best result. All About Needles

Tread bunches up under the material what is the fix

Sounds like what you are experiencing is bird nesting or thread nesting.

First, install a brand new needle. (Most frequent cause of sewing problems.)

Remove all the thread and rethread from the beginning BUT be sure to RAISE the presser foot BEFORE threading. This allows the thread to seat firmly in the tension disks.

Set the upper tension at the midpoint (this is the standard factory setting).

Test your stitching. If the thread is still globbing under the fabric, tighten the upper tension and test again. Keep testing until the upper thread and bobbin thread meet in the middle of the fabric.

Here's a suggestion to help avoid thread nests at the beginning of sewing:

What adjustment can I make to my lower looper, thread does not stay under pressor foot while sewing

thread tension can be adjusted by the small screw that holds the spring plate on the bobbin carrier under which you have to pull the thread after the bobbin is placed in the carrier
a small movement is a lot of tension adjustment
if the thread is bunching up under the material ,that will be the needle thread tension and it needs to be tightened

Can't get Juki tension right

which tension is wrong
if thread is bunching up under material increase the tension of the needle thread if the bottom thread is loose then increase the bobbin thread tension
each thread result for above or below material will indicate which thread to alter the tension on

Embroidering in blue thread, and the white bobbin thread was coming through on the material. Adjusted the tension to -8, sprayed the bobbin casing and area lightly with WD40, changed the bobbin, changed...

The white bobbin thread was showing on the top of the material correct? Make sure bobbin thread is in the tension correctly, check the top thread spool and make sure thread is not caught around it, if you have a manual top tension make sure that is set correctly. Personally I would never use wd40 in a sewing machine, sewing machine specific oil is always better. You seem to be describing two different problems. The thread bunching is probably from the thread jump out of the take up lever.

When i sew the bobbin thread bunches up. what to do?

remove the thread and bobbin.
take out your manual and follow the exact instructions for threading and inserting bobbin.

If this does not help check the tension on the top(the number should be about mid way).
If it is too low it will bunch up on the bottom.

Thread is bunching up unside of the material does not catch bobbin thread

This sounds like the tension is not set properly for what you are sewing.
