The learning curve is moderate, and they have higher-end versions available if you create products that need sheet metal designs or other complicated features. The next step down the software chain is CAM software, which is responsible for taking your designs and creating a toolpath for the machine to follow to cut out your parts. There are many CAM programs out there, and most are very expensive.
Luckily, there are a few free cam software options out there. Examples of 2D parts might be gears or signs. It is not cloud-based. Carbide Create also has a vibrant user community online. Inkscape allows you to download and install plug-ins to create G-code from within the software eliminating the need for additional CAM software. Inkscape is a popular design software, and the official website has many tutorial videos to get you started.
Furthermore, you can find videos on YouTube to guide you through your design works. OpenBuilds is a CNC manufacturing company that started as an online community supporting the open-source maker movement. OpenBuilds CAM is a web-based software and requires you to have an active internet connection to use the software. The bright side is all the processing is done on the server-side, and you do not need to install heavy software that bogs down your computer. On the support end, the huge community of users have a solution to all of your problems and are prompt in guiding you through troubleshooting.
It is a simple and easy-to-use software best suited for hobbyists looking for free software to use with their CNC machines. The free version has some limitations compared to the paid version but has enough capabilities and features for most hobbyists. It can run simulations based on G-code and machine parameters like machine size, type of tool, and workpiece position. Instead, they work based on the control signals they receive. This software directly generates the control signals for controlling CNC machines and sends them to the machine parts via breakout boards.
It is a control software developed based on the open-source Linux platform making it free to use and modify. LinuxCNC is a popular machine control software that has been around for a long time and is the root of several control software programs like the popular Mach 3 software. You can control up to nine axes using LinuxCNC control software. To perform such feats, you need to have good data transfer speeds between the computer and the machine.
LinuxCNC uses parallel ports to communicate with the machine as parallel ports are significantly faster than USB ports in transmitting instructions. If your computer does not have a parallel port, you can use ethernet breakout boards to interface your CNC machine and computer using an ethernet cable. Using an ethernet card aids you in hardware step generation and encoder counting, which is not possible using parallel port interfacing.
As it is an open-source platform, several customized versions are available that add certain functionalities or tweak the user interface and appearance. LinuxCNC supports pendant control, and it also allows you to interface touchscreen controllers easily.

Fusion is free for non-business users and some small business users. Back to Homepage. Shop All Our Products. So check out our free stuff! The ultimate productivity hack for busy people—the same ToDo list with Pomodoro timer system I use myself to get all this crazy stuff done for CNCCookbook. Free G-Code Editor? Free CNC software, demo and trial versions. Why we created this free download area. If you are more and more interested in buying a CNC router to put your workpieces into action, we gladly advise you about the following questions: Which machine is suitable for the size of you workpieces?
Which accessories do you need to machine your material? It reads the G-code instruction and converts them into commands that the breakout board can understand.
It can also be used to manipulate your CNC machine manually. LinuxCNC has been around for a long time and has been used to develop other software such as the Mach 3 software on this list.
It can control up to nine axes simultaneously. However, a USB interface is not recommended as USB communication is slower in transferring instructions than parallel ports. You can even run it on Raspberry Pi4 and above. It uses the parallel port on your computer to interface with your CNC machine.
You can also use the ethernet port to interface your machine via ethernet breakout boards the most popular ones are from Mesa. However, using an ethernet card such as mesa helps in hardware step generation and encoder counting rather than using just a parallel port cable.
LinuxCNC has a large online community, and the software itself has a forum-like feature that lets you post questions to other users around the globe. It has a graphical user interface that is highly customizable, and it supports touchscreen interface devices and pendant controllers. However, PlanetCNC is a combined hardware and software solution. This controller is then connected to stepper drivers.
If you wish to connect this controller to a parallel port stepper driver like the Gecko , you need to buy the DB25 adapter that's sold by PlanetCNC. Apart from generating G-code, you can also edit the G-code you have imported and scale the design according to your workpiece size. You can download it from the UGS Github page for free.
There are two options to choose from, the classic and the platform. The platform is the recent version and is more advanced than the classic version in terms of the graphical user interface and support for various controllers.
It is a control software that interfaces your computer with the CNC machine and is best suited for hobbyists. I liked the graphical user interface to be quite intuitive with a well-organized and clutter-free design. You may also simulate or edit your G-code.
You can also use your smartphone to control jogging by connecting it to the same WiFi network as the computer. It can be downloaded from their Github page for free, and you can install it on Windows or Linux computers.
The user interface is minimalistic and easy to use. Furthermore, you can map keys on your keyboard to control the axes. You can import, view and edit G-code. In addition, you can view the path the tool makes before and while cutting. The interfacing with the controller is via USB. However, it can only support a maximum of 3 axes. It is suited for hobbyists and DIY enthusiasts. These are software that are run only on the controller hardware of the CNC.
This firmware is connected to the computer through a USB connection and does not need a parallel port, which is a major advantage. Primarily due to the popularity of Arduino.
There's a large community of people who contribute to GRBL and that helps in the constant development of the software. These software programs are used for simulating the G-code you obtain from CAM software.
It helps you predict the problems you might face when you do actual machining using G-code. You can visit their website and input the G-code your CAM software generated.
NC Viewer is a web-based software. Hence it can run on any OS platform, and hence is a good choice when you need a quick check on your G-code. You can even use it on your smartphone.
