Cannot get accurate camera aid background for laser


Hi there!

I’m getting good results overall with the laser engraver, but so far I’ve been unable to get this working properly… after following the steps (accurately as far as I can tell) Snapmakerjs v2.5.2 Beta Testing
I generate the gcode and start engraving, but the result is pretty significantly off the mark.

Did this test with the “Fonts”. Image:


Any advice? What am I missing?



The angle of picture can affect the result significant, and the selection of the 4 corners.


I tried it as parallel as possible, and also at various angles just for testing purposes… seems to be more or less the same. Getting the corners very accurate is a bit difficult as the window is so small and cannot be resized.
