Help Seamsters! Why???
Sewing Gurus, what do you think is going on here?

Sewing baffles into my UQ. Mara 70 bobbin and thread, Brother 6000i, 12 or 14 needle isn't new. Every time I get going a little fast, over half speed or so, I get a jam up. I'm getting near the end of the thread and it starts dancing around some when I get going fast, causing some slack I think...
Wonder what the culprit is likely to be?

It looks like you are not getting the bobbin wound smoothly at the start. Winding the bobbin needs to medium speed and very smooth from the very beginning. It is important to maintain a steady speed and not bounce fast to slow to fast jerk and stop.
The same thing can happen with a spinning reel... birds nests. Real pain.
That's my assessment from the photo.

Thanks RamblinRev. I was hoping you would be on call. :)
Well it happened on two different bobbins and I'm real careful about winding them evenly. Decided to change to a fresh #10, swap out bobbin and go to a new spool of Mara 70.
Can't argue with that logic! Working fine now!

I spoke too soon...

Thing is, it flies through my test fabric, t-shirt cotton. Guess I'll just try to limp through this project more slowly. Rats.

Did you state your needle is NOT new? Put in a NEW needle. Your thread looks heavy is it? Your thread and needle need to match, a couple of prior posts have the types of threads that go with different sizes of needles and fabric.
Get in and clean your machinge, take the bobbin apart clean everything, look for the nasty little threads of parts of thread or lint hiding, use a little compressed air to clean everything.
I bet you have a little lint or bit of thread boogling up the action of the bobbin. Maybe check to see if your timing is correct. Are your feed dogs engaged correctly?
If all else fails have someone trustworthy look at your machine.

Try putting a little less thread on there. For starred take of @ 1/16 and spin it up. Had same issue on my zig zag. I never fill them up all the way to when the machine says its full.

Also double check your needle isn't 180* out. I had mine in backwards and worked great on everything until my main fabric. Even worked at slow speeds. Soon as I hit the go pedal I was hosed

It wasn't a new needle but it is now. I swapped it before that last fail. Can't put the needle in this machine in the wrong orientation. I've sewn a thousand miles with this needle thread combination.
I'll clean it out and load a fresh bobbin and see if that helps.
Thanks everybody!

Maybe a heavier duty needle?
