How to create the gcode to create a 3D model of the terrain
To create the gocde for our cnc for the realization of 3d terrain models there are various procedures and software. Some more complex, others simpler. It also depends on the software you are going to use. Those who follow my channel now know that I prefer the use of open source software. We already spend a lot of money for our entertainment which, when possible, is better to save. The procedure that I am going to describe here is quite simple and is completely implemented using open source software.
For the generation of the actual gcode I use dmap2gcode which you can download at this link while you can download the images to be used for the creation of the digital terrain model at this link.
The procedure in dma2gcode is quite simple, we will not have to do much more than go and set the usual parameters of our cnc (feed speed, z lunge, step over, etc.).
For the improvement of the images in order to make them optimized for the generation of a 3D terrain model with greater highlighting, I am going to use Gimp, raster graphics software, also open source that you can download at this link and, as an option, also QGis, which you can download at this link. While the first one is easier to use and specific for the operation we are going to implement the second one is of a different nature, it is a GIS software. The second one I show only because by the same, later, I'll go to show other things that can be done for our cnc using its features.
In this video I'm not really going to make the work, I didn't have a particular project in mind, but the operations are actually the ones we need to create a gcode that reproduces a 3D model of the ground faithful to the original. When I am inspired, he gives some ideas, I will go and make it. So for the moment I only show the procedure to be implemented.
