One thing I've noticed and have seen on other threads is the tension of the needle, to much or to little. The way that works for me is bending the needle like you would using a coil and rubber bands. but when tightening the needle, tighten down the needle bar to where it looks straight again, and for me that equals the right amount of tension.
