Feature suggestion: Change grid in viewer

[cra 0]

I think it could be practical to be able to change the grid on the viewer to match a grid on the actual bed. I am thinking of lining up a grid on my bed to help place parts/apply glue, but the current grid in the viewer is too fine masked. If it was possible to add an image that would be very helpful, or even just being able to adjust the grid distance. 1cm is a bit too fine grained. Perhaps a possibility to make every n-th line a different color/thicher line? Then it would be possible to mark out say a 3cm or 5cm grid on both the screen and the actual bed.

I too would like this.  It would make setting up my camera for octolapse easier if I could make it match the markings on my Prusa.

Nothing on this front yet?

Open C:\Program Files\Ultimaker Cura 4.13.1\resources\shaders\grid.shader in a text editor
 

Line 81			        vec2 minorGrid = abs(fract(coord - 0.5) - 0.5) / fwidth(coord);

Line 87					vec2 majorGrid = abs(fract(coord / 10.0 - 0.5) - 0.5) / fwidth(coord / 10.0);

In line 81 change the .5

In line 87 change the first 10.0, and both 0.5


If anyone can make a Cura Plugin to help do this without editing the files, please contact me
I also have other ideas for plugins

 

If I set it to something like...

10.0, 10.0
10.0, 0, .5
The scale is set to 10mm, you can change that to whatever.

Not sure what that 0 does.
If you leave the .5 as is, it will offset the first squre to the very middle square to be perfectly center. Set this to 0 if you want that to be offset
