I bought the same machine. It does require regular cleaning/oiling and good quality thread. I use Superior, which is all my guild uses on our LA. How often do you change needles? When I had a problem, DH found that I had a tiny burr on my embroidery foot (my fault). He used emory cloth to get rid of the burr. I have switched to platinum needles. They last longer. Use the correct size for the project.
