All I can tell you is that I was having problems with it too and found out it was "OE" (operator error!). I didn't press the BSR button on my machine! When I use it on my machine to do meandering stitches they don't come out uniform, so I've been told to use it in BSR #2 mode. Also, I slow my machine way done to almost as slow as it can go. If your stitches are too close, you are moving too slow - if they are too big, you are moving too quickly. And practice, practice, practice! Hope this helps!
