CNC Router Software The Glamorless, Crucial Component

If you want your CNC router to run on your computer, there are three parts to your toolchain: computer-aided design software (CAD), computer-aided manufacturing (CAM) software, and a machine controller package.

The part in question will be drawn or designed in CAD software (like AutoCAD), the CAM program will then convert the CAD drawing into G-code, and finally, the G-code will determine the actual movements of the router as it makes the part.

If you happen to be using a commercial CNC machine, the controller will be built into the machine, and you only have to directly transfer the G-code. In the meantime, such is not always the case with hobby CNC machines, which have an external controller. This external controller could be, for example, a personal computer connected to the CNC router.

In this article, we focus on this standalone CNC control software, which is used to create tool paths for CNC machines – determining its movement – by sending real-time commands. Typically, the CNC control tool runs on an off-the-shelf PC that is normally interfaced to the machine.

CNC control software essentially turns your computer into a machine controller, but picking the best software can be a tricky affair because there are several things to consider:

  • What type of CNC router are you using?
  • How much are you willing to spend?
  • Are you a hobbyist or an industrial user?
  • What hardware are you using?

These are some of the most critical questions you need to ask yourself because no one wants a buggy and non-intuitive software.

Thankfully, we’ve navigated the choppy waters of CNC router control software to bring you five tools that are sure to impress. They’ve been picked based on their popularity, reliability, and ease of access. Under each tool, you will find the main features that make it unique.

Cost: $200 (Hobby); $1,400 (Industrial)

Operating system: Windows

Mach4 is the newest edition in the Mach series, written from the ground up to be flexible, expandable, and super responsive. It’s the best pick when you need industrial style methods and controls, with a modular architecture that allows for faster development to expand its feature set.

The modular design allows features to be added or subtracted without affecting the system operation. The result is a customized software package, making it more adaptable to different machines, applications, and uses.

Main Features:

  • Ability to control or track CNC equipment remotely
  • Ability to change display, indicators, and buttons quickly
  • Improved screen layout and customizable screen modification tool
  • Linking information between other computer applications
  • Ability to pan, rotate, view, and scale the tool path quickly
  • More accurate tool path compensation
  • Core responsible for all motion control calculations (improved backlash control, up to 100x faster machine action response from a button click, and a higher quality manual pulse generator)
  • Multi-axis work shifts and head shifts

Mach4 Industrial is for the manufacturing environment, where every second counts, while the Mach4 Hobby is for those interested in using CNC machines for personal use.

Cost: Free

Operating System: Linux

Without a doubt, LinuxCNC is a worthy opponent to the Mach series. It’s a popular choice among most CNC hobbyists mainly because it’s free and completely open-source.

LinuxCNC uses a Linux kernel with real-time extensions (RTLinux or RTAI) and has the capability of controlling up to nine axes or joints of a machine. The software can also handle peripheral machine elements like tool-change procedures, cooling, and tool length measurement.

Main Features:

  • Full source code available under the terms of the GNU GPLv2
  • Easy to configure
  • Multiple preconfigured GUI templates
  • Simple installation
  • Very active user community
  • Compatible with several popular machine control hardware interfaces
  • Supports cutter compensation, rigid tapping, and other advanced control features

Cost: Free (with controllers that have a valid license)

Operating system: Windows 7, 8, 8.1, 10, Linux, Raspberry Pi

PlanetCNC is designed with flexibility in mind, especially for the coordinated movement of servo or stepper motors. The tool is user-friendly and will allow newbies to employ advanced functions with ease.

PlanetCNC has useful G-code manipulation (edited, scaled, mirrored, rotated, shifted, copy-pasted, bookmarked) and transformation functions. Its configuration options allow users maximum integration, flexibility, and customization, and the simulation features are designed for fast verification of NC programs.

Main Features:

  • Fully-configurable tool change procedure
  • Supports simulation, spindle synchronization, measuring, probing, and canned cycles
  • Standard RS274/NGC G-code with extensions to achieve full LinuxCNC G-code compatibility
  • Supports user-defined M-codes
  • Can additionally import Gerber, PLT/HPGL, DXF, NC Drill files
