Without warning machine makes "ka-thunk" noise and 10-20 loops appear on bottom of project. Often will stop sewing completely.
To address my needle thread tangling (horribly) in the bobbin compartment, I rethreaded the bobbin. I cleaned the bobbin and the feeder feet, I changed the bobbin and the thread. I changed the tension on the needle thread and the bobbin thread. NO FIX! Then, I changed the needle - the problem was fixed instantly. I sewed awhile and then put the original needle back in. No problem. I think perhaps that the problem is being caused by the needle getting out of alignment somehow during sewing. If you are having the same issue, try it. It can't hurt!

Check your threading.
Berhaps your thread is not between the discs.
