S Singer curvy 8770 beeps after a few stitches!!

I'm sure you've done this, but I'll just throw this out there. Did you pull the bobbin thread through the groove that slants on the left side of the needle plate starting from the upper left corner of the bobbin cover?

Are you getting any error messages? This page may help: http://www.manualslib.com/manual/364636/Singer-8770-Curvy.html?page=30
It would be something really simple like the bobbin winder not completely in the right position. I hope the troubleshooting page will help.

try a new needle
make sure the bobbin is turned the right way in the bobbin case
rethread the machine top and bobbin
if these suggestions don't help, then the machine needs to be checked

Some sewing machines are extremely finicky about the direction the thread feeds from the bobbin. I had one machine that didn't care which way the bobbin fed and another that would stop after 2-3 stitches and protest. You could try flipping the bobbin and see if that helps.

do you have a manual?
try a new needle
adjust the top tension
try rethreading the machine top & bobbin

when you thread the machine make sure to use every thread guide
check to see if the bobbin is in correctly
try changing the needle--normally flat side goes to the back
the needle that your sewing with is it the right one for the thread & fabric
clean under the needle plate & bobbin area for lint or loose threads

Good day!

Thank you and good luck.

Be sure to change the needle often.

Sounds like bird nesting.
Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.

Try this, totally rethread with the presser foot up, then pull the top thread, it should move smoothly, then lower the presser foot, now pull the thread, it should barely move. This seats the thread in the tension discs.

A. To correct loose stitches, try the following: (1) Balance the thread tension. If the stitches are loose on top of the fabric, decrease the tension to the next lower number. If they are loose on the underside set the tension to the next higher number. (2) Make sure the needle/upper thread follows the threading path. (3) Check to see that the bobbin case is threaded properly. (4) Use a different size needle. For fine fabrics, use a smaller needle (size 9, 11); medium-weight fabrics require a size 14 or 16. And use a size 18 or "Denim" needle for heavy corduroy or denim.
