Laser not starting in the assigned position

I recently purchased an Xtool D1 Pro with 40 wt laser. I am using the purchased Lightburn Software. Evey time I set the laser spot exactly where I need it to be then push start it moves 5/16’ to the right. Why and how can I fix this?

Are you using the crosshairs for aiming? I assume not based on this. If not, then disable the Laser Pointer Offset in Edit->Device Settings or turn on the crosshair in XCS.
