Some people get a so-called offline controller with their machine. Your 3018 CNC will require some type of machine controller. The GRBL software is embedded into your machine, though, it’s not made for you to use directly. GRBL is an open-source program that coordinates the three motors on your 3018 to cut out your parts. Internally, the 3018 uses GRBL firmware for motion control. If you’d like to see how all of that works with your CNC machine, you can try for 15 days MeshCAM here. You might use images with your CNC machine to:Ĭreate a simple project based on scanned artwork from your kids. MeshCAM is able to load image files and convert them into a heightmap based on the brightness at each pixel. Image files are not usually used in CNC machining. It’s become a popular alternative to DXF in 2D design programs. SVG is a 2D file format originally created to use on web pages. If possible, it’s better to use the older versions of the DXF format to ensure the broadest compatibility. It’s still very popular, but compatibility can be challenging because it’s a complicated format without deep documentation. What are DXF files used for?ĭXF is a format that was originally created for use in Autocad for 2D designs. MeshCAM Pro supports loading STEP files, and that’s the preferred format if you have the option. You’ll find that most mechanical CAD programs support STEP import and export. STEP files are used by higher-end CAD programs for parts that need to be very accurate and editable. MeshCAM makes it easy to convert STL files to G-code. The primary downside to STL files is that they’re mainly a read-only format very few CAD programs can edit them. They’re supported by almost all CAD software, and complete cnc projects in 3D are available to purchase online for very little money. Originally made for 3D printing, STL files are used as a simple format to exchange 3D files. MeshCAM supports all of the standard CAD file formats (STL, STEP, and DXF files), as well as some more artistic file formats (images and SVG files), while keeping a simple user interface. CAM software takes your designs and converts them into G-code, the language almost all CNC machines use. We make MeshCAM, so this is our specialty. If you bought a 3018, you were probably attracted to it by the price, so you’ll be happy to know that a couple of the CAD programs linked to on those pages are free software. We maintain two lists of CAD software that we recommend so we’ll link there instead of repeating it all here: In many cases, you’ll use separate CAD and CAM software. They are the software that you use to create and modify designs and to create the machining instructions to cut parts. Meme posts that are not funny may result in a permanent ban and possible curse to post author.CAD and CAM software are “computer-aided design” and “computer-aided manufacturing” software applications, respectively. Memes are not permitted, unless they are CNC related AND funny. Please use the stickied sales and services megathread. Sales and or services posts are not permitted. Final decision is made by the community by way of reporting. Other considerations that may cause the removal of the post including lack of engagement with the community or the author has a history of self promotion. Posts that do not meet this criteria will be removed without question.

Name calling or belittling will not be tolerated and may result in a permanent ban. Please be respectful of others when posting. If it appears the author has done little or no research it may be removed for low effort. Posters are also expected to have done some basic research on their own. Post authors are required to stay engaged with the community. Any posts without this information may be removed and only restored when the information is supplemented. You must include as much useful information as possible when asking for help or advice. Examples of this include unsafe instructions and unsafe modes of machine operation. No posts or comments that encourages unsafe acts.
