![]() ![]() To learn more about Marlin, see What is Marlin?. After downloading the file, simply import it to the software to generate the correct G-code for your Snapmaker CNC Carving Module. Currently, we provide posts for ArtCAM, Aspire, FreeCAD, and Fusion 360. The firmware of Snapmaker 3-in-1 3D Printer is developed based on Marlin. Other widely-used firmware includes GRBL and Klipper. Marlin is one of the most popular 3D printing firmware. Products made with Snapmaker CNC Carving Module This means that you need to know what language your machine speaks (i.e., its firmware type) first and then select a translator (i.e., a post processor) that works for it. The firmware of your CNC carver determines the type of G-code it can read. For 3D printers, firmware is responsible for transforming G-code into control commands that tell your CNC carver what to do. A post processor can be either stand-alone software or integrated into CAM software.įirmware is a special kind of software that is embedded in hardware, resembling the operating system of your computer. ![]() The file that post processors use for such translation is called a "post". ![]() Post processors translate the dialects into the one that your specific CNC carver can understand and execute. You can think of G-code as a collection of different "dialects". But in order to successfully carve out the finished product, a crucial step is to make sure that your machine can effectively recognize the G-code output by the CAM software. Now, it's time to move on to two new terms: post processor and firmware.Īs mentioned before, your design can become G-code thanks to CAM software. The two processes complement each other and are equally indispensable. In a nutshell, with CAD, we transform ideas into designs, and with CAM, we manufacture real products based on the designs. With simulation and error check, you can preview the path of the tool on the material surface and judge if the carving will go smoothly. The toolpaths in the G-code tells the machine what to do in order to carve the geometric forms depicted by the model, such as round corners, bosses, and grooves of the toy car. Next, you use software to transform the model file into G-code. First, you need to turn the imaginary toy car in your head into a model file, which is essentially a collection of geometrical data. Usually, it also includes operations like simulation and error check to minimize the risk of going wrong.įor example, you want to build a toy car. Computer-aided Manufacturing (CAM), on the other hand, corresponds to the second step, through which models are transformed into commands (toolpaths and the corresponding G-code) that tell the CNC machines what to do. It covers aspects related to model designing, such as conceptualization, detailing, modification, etc. ![]() Third, import the commands into a CNC machine to start carving till we obtain the finished product.Ĭomputer-aided Design (CAD) refers to the first step in this workflow. Second, transform the model file into commands that CNC machines can execute. We already know that, in the CNC workflow, three steps are required to turn an idea into a finished product. First of all, what are CAD and CAM? CAD vs. Now, let's turn to CAM and check out four CAM software picks suitable for CNC carving.īefore jumping right into CAM software, let's go through some basic concepts. The three previous episodes focused on CAD and introduced some practical modeling software and websites of modeling resources. Welcome to Snapmaker Academy! This is the fourth episode of our CNC series. ![]()
