Hi everyone
Brand new here and to blender!
I have made a simple 3d image of a half oval shape, that I want to open in lightburn to deep engrave it, but I cannot get it to open in lightburn
Ive saved it as .SVG and tried importing it to lightburn, but I can’t get it to work
Can anyone here tell me should it be in a different format, or possibly have I done something wrong, or do I need to do something else?
*.svg is NOT!!! a 3d format
it is a 2d vector image
Thanks for your reply JonnVV…
Maybe I am going about things the wrong way. I have a fiber mopa laser and want to deep engrave an oval shape into metal, and because I am struggling to get a suitable 2d image that I can use in lightburn, I thought maybe I could create a 3d image of what I need, and transpose it somehow to a file format that can be used in lightburn.
Maybe, I am doing things wrong here, but I am just struggling to get what I need
Hope you can advise!
Thanks again

for something like that it looks like you might need a depth map ( heightmap)
you can place a camera directly over the half oval shape and render the z-axis
save as a exr
normalize it ( i use a program called " nip2" ) and resave as a tiff
and the vips lib GUI - nip2
your laser cutter i think should be able to use a 32( or 16 bit ) tiff image
Thanks again for this information, it looks really helpful for what I need, but the probelm I am having is that I have tried to render it around two dozen times nearly and it crashes every time, I have even uninstalled and reinstalled blender! My GPU is a Radeon RX 570, 16GB ram, Processor Ryzen 9 5950 x, but the GPU Spikes and causes it to crash. Any suggestions what I can do?
I managed to sort out blender crashing everytime i go to render, which was an update to my system directly from Radeon AMD
I then rendered the object/file to .exr
Then downloaded nip2, but I cant get the .exr file to open
Am i doing something wrong?
Any further advice would be great
Also, is there a way to render it including the number of passes ie 256, and should this be done in blender? and is this creating a depth map? have i missed something?
Again, this is down to my lack of understanding, but I understand a fiber mopa laser works by emitting laser power based on the depth of each pixel in a 2d image (black = max power, and white = min/no power) and therefore, creates a 3d engrave. And it is this that confuses me as to why a depth map is necessary?
I think lightburn supports 2D.
It doesn’t seem to support height values like 3D printers.
It is a program that cuts with a laser along the outer line of the 2D vector.
You can view tutorials in the link.
Im obviously missing some step in the process to make a 3d depth map image using blender, I have rendered the image and saved it as a png file, then imported it to light burn, but the image does not show any grayscale gradients, it needs to be engraved as a half-oval shape
I need some help, can you please advise what I might be doing wrong
