NC Viewer is a popular handy CNC simulation software. It is free and its cross-platform compatibility gives everyone a chance in the CNC simulation world. Some of the main highlights of this software are that it is free-to-use open-source software that can work in offline mode, and is not limited to just one OS.

There is a Google group for CAMotics users where you can discuss your issues, active discussions are happening through Reddit also. Since it’s free open-source software, it has huge community support. It provides simulation settings, shows the data of the simulation process, and has a status bar to notify errors. The user interface looks like that of Windows XP and is pretty easy to navigate. One problem I found while using this software is that it can’t estimate the overcutting and undercutting which happens during a regular milling operation.ĬAMotics website has detailed documentation of how to navigate and use the software. You have the flexibility of editing G-code while using this software.It comes in handy when you find an error in the G-code simulation, it can be fixed by editing the G-code. It allows for a 3-axis simulation of the workpiece in a virtual 3-dimensional space. The software works offline, which means you don’t have to be connected to the internet to run the software. If you have a multi-processor CPU it can help the software with multi-threaded rendering. It’s compatible with 32 and 64 bit Windows, Mac, and Linux-based operating systems. CAMotics is an open-source software, which is freely available for anyone to download and use.ĭon’t get confused by its name, it can’t perform CAM operations as of now, for that you will need additional CAM software.
