Can anyone explain the Check Size feature in LW,

Can anyone explain the Check Size feature in LW, I can’t find any documentation on the internet that explains it in any detail.

Thanks.

The router will move around the generated gcode. So you can check if your workpiece is locateted correct.

Should the laser come on at low power while its doing that?

No

It’s supposed to be if you have a laser pointer attached so you can see where the laser will do the outer borders, if I recall correct.
