Next, change the number of passes entry to the quantity you intend to use for this operation. Open the Cut Settings Editor for the layer the image you've imported is on, and change it's type to '3D Sliced'. How-To ¶įirst, produce a greyscale heightmap image in any tool you choose and import it to LightBurn. 3D Sliced mode uses the depth map to generate up to 256 steps of engravings, with impressive results. The greyscale powermap can be imported to LightBurn like any other image. These can be created by hand, although tools like STL2PNG that generate raster images from STL files are often used to make more complex depth maps. Darker shades of grey will be cut with more passes and become deeper, while lighter shades of grey will be cut with fewer passes, making them shallower. LightBurn calls this mode '3D Sliced' due to the similarity to 3D printing slicers where horizontal slices are deposited by 3D printers, LightBurn allows subtractive layer-by-layer operations.ģD Sliced mode uses greyscale images called powermaps to create depth in the engraving. Galvo users without a live Z-axis have the ability to make '2.5D' engravings with LightBurn and their galvo, producing objects with tactile and visual depth. Be sure to let us know on the forums or via support if we need to change something. This section is new, and is a work in progress.
