Can you post a picture of the screen with the laser light? Are you using the Left/Right shift function? There are two different ways to use the light. I use mine centered on the center seam line (straight out of the needle).
There is another button that moves the light. You can see the light and where it falls on the seam line on the screen. Which way are you using the light? Is this what you are having issues with on the machine?
OR: is the light pointing crooked? I want to be sure that my reply is helpful.
I have the machine and love the light. No issues at all.
PS: Have you set the light with the pen function? That might help re-set the light too.
Good Luck!
