Renee-were you free motion quilting when you were having problems? Sometimes I have problems with my machine if I am using a different kind of thread and I am free motion quilting.

I recommend rethreading your machine (and the bobbin) with thread you usually use and try just sewing a normal seam and see how your bobbin acts. If it is still messing up, then you may need to have your baby checked. If you have been doing a lot of sewing, it may need to be serviced more than once a year. If it is sewing just fine, then change just the bobbin and see how it sews, then the top thread, etc-changing (and then sewing) just one thing at a time and see if you can then figure out what it is that is making your machine not work correctly.

I changed my stitch setting to zig-zag once and forgot to change the foot-when I started sewing I "jammed" my needle onto the foot and it threw off the timing in my machine--it messed up my tension and was a costly mistake to repair. The repair man told me I should hang a photo of my credit card over the button to switch to zig-zag so I would remember to change the foot next time!!

Hope you get it figured out and let us know what the problem was--we can all benefit from each others knowledge!!!

I had the same problem and found that my bobbin was wound too loose. If I go too fast when winding the bobbin it doesn't wind tight and then I get the loose thread underneath.
It's hard to tell when the bobbin isn't wound tight so try pulling on the tread and you'll be able to tell if it's wound right.

I had a similar problem with my Bernina and the solution was that, even though I've been sewing for 50 years and on this machine for 3, I forgot to put down the pressure foot. I kept just repeating all the wrong steps - finally, I shut the machine off, rethreaded it, cleaned everything, went back to the usual thread I used before changing to the current one, and then realized that the step I was missing was putting down the pressure foot. When all else fails, though, take it to your dealer.

My machine is a drop in bobbin, it is a kenmore......the bobbin thread has to be going in the right direction.....it never made a difference before....I keep forgetting it,,,and about 50% of the time I have to flip the bobbin :roll:

About all my problems with the stitching is either the machine is threaded wrong (rethread starting from the very first thread guide) or threads & lint caught in the bobbin case.
It's much easier to rethread and clean the bobbin case first.

I'm one of those that can break any sewing machine in 10 minutes or less - I now do all my quilting by hand. When I see problems like this pop up, I'm sorry for the quilter, but glad I don't have those problems. I guess in olden days I'd have been one of those passing a broken-down Model T yelling "Get a horse!" (Not really!)
Hope it all worked out well for you!

This justed happened to me and I called the service people they told me to take it in, I'm still with out my machine, after cleaning and changing needle I had to tighten my tension. Everytime I wound a new bobbin(very clean, that wasnt the issue) I had to take my bobbin cassing out and tighen the screw each time, this machine isnt even a year old (babylock esante). So when I find out what the problem was I will tell you. I hope it's just that I might need a new casing

Guess all I can add is Good luck ...hope you get it fixed...do you have back up machine???? Hugs your way hope all gets fixed!

Just an added thought: to clean the machine, I found the canned air is great. I take my machine outside once in a while and spray the heck out of it.

Thank you all but I ended up with multiple issues and I have fixed the problem.

1. My darning foot has a nick errrrrrrrrrr
2. This thread sheads alot so alot of cleaning inside errrrrrrr
3. Something with the bobbin wasn't right also errrrrrrrr

Changed out the bobbin, rewound, going to get a new darning foot and start praying all works well from now on. lol

Thank you again
