Embossed Lettering on a CNC Router: Design → G-Code → Real Cuts (No Paid Software)

[Music] So, let's create the tool path to mill this letters. And I created something a little bit more complicated because I want to show you the power of Blender and the Favx CNC add-on. I've made two layers. The CNC text is higher than the eight slip and repeat text. So we are going to split this into two operations, but the results will be more interesting. Of course, I could make a simple tool pass 3D surface tool pass, but I don't want to do that. I want the letters to be nicely contoured. I want the edges to look good. And that means I have to create a tool path that follows the shape of the letters. Before starting the operation, I want to talk to you a little bit about the tool bit and the importance of the tool bit. Because the remaining pieces, the letters are going to be very small pieces of material. There's a high risk of the material breaking. This is why I'm using a down cut bit. it tends to push the material down, which means there's a less chance of pieces of wood to trying to fly away. How do I create a tool path that follows the shape of the letters in Blender using the Fab CNC add-on? I can easily do that by going here, going to the curve tools, and select the get pocket surfaces option. And even though it doesn't do anything at first, that is because the Z limit is set at zero. This is a top limit. So I want to set it equal to the total height of the object which is 16 mm. Once I change this, you can see that I have four objects for curves created in the tree. They are also grouped in a separate collection, the multi-level pocket. And that is really useful to make G-code to follow certain shapes when I'm using a mesh. [Music] Now let's identify what represents each of these objects so we can rename them. First I have this base 002. Let me just hide the 3D object. So the base 0002 is an outline of the entire text and the plate. Press F2 and name it entire object. Base 003 is the top text which in this situation I don't need. So I can delete it. Base 004 is the CNC text. So let's rename it CNC text. And B 005 is the repeat text isolated.
