Ok, I have adjusted the attention, changed the needle, rethread and I'm still breaking the thread. I'm using Superior Thread OMNI, what am I doing wrong? I also have issue with the stitch regulator when I'm doing designs that go up and down the machine jumps big stitches or doesn't move? I get needle walking error all the time, and sometimes it sounds like gears are grinding inside the throat area when this error happens! 've only had this machine two weeks!
