I have a Snapmaker 2.0 A350T with the quick fit kit and the 10w laser.  
I am finding that the laser is engraving lines between the shapes and when I checked Luban (which i used to create the shapes - Luban Version 4.9.0) I found that the app is actually inserting a light blue line between the shapes (diagonal from the top left corner of the squares and a horizontal line as well) when I create the toolpath, so it seems like the laser is also burning this line. I am using vector engraving on path and I have tried with the ‘laser constant’ setting on and off and it makes no difference - the laser still burns the line between the shapes.  
I am just wanting to burn the outline of the shape ‘on the path’, so presume I am using the correct setting.

Upgrade the firmware in your snapmaker to at least 1.17.17. There was a change in how the laser works when Luban 4.9.0 was introduced.

Thanks, that fixed the issue - I’ve updated my machine to V1.18, my machine was on V1.16.7.20230727.
