Preview is showing 5 minutes and the real time is 16 minutes

In lightburn preview the time shows 5 minutes to etch. It shows both etch time and movement time with a total time of 5 minutes. I start the etch and it ends up really being 16 minutes. What am I missing?

Lightburn computes these from what’s in your controller…

You can go to “Edit → Device Settings → Additional Settings” These are generally read, but you can click ‘read’ and you will see a change if it hasn’t been read already. Note the RED text.
