Need to find the setting to turn OFF the laser at end of scan lines.

Most likely what you need is to enable overscan. The darkening at the ends is caused by the head slowing to change direction, and enabling overscan lets it maintain speed right to the end of the cut, and it slows down during the overshoot. You might need to adjust the default to a value that’s appropriate for the machine.

Is this the one you are referring to?Over

Double click on the entry in the cut list to bring up all the extra settings.
Then enable overscanning here:

Ah…ok got it, thanks
