I too have a Brother/Laura Ashley NX2000 machine (which I don't consider inexpensive) and have had issues with the bobbin/bobbin case. I've had the machine 14 months and am on my third bobbin case (1st came with machine and somehow it got a broken hook - don't know how I did that; 2nd got burrs on the outer edge - probably from unnoticed bent needle since there were needle scars on the top of the case - says my tech.)
I used a walking foot to quilt a lap size with a cotton batting. The tech was quite convinced that I force-fed through the feed dogs.
Been sewing for 50 years with Singer/Viking/Elna and now Brother/Laura Ashley, Janome embroidery, and Elna serger so I'm not new to the rodeo but sure am new to replacing bobbin cases!
