Choosing Software 🎛️


Whichever software toolchain you choose should make the most sense for you and your CNCing ambitions. A good, personalized toolchain should meet your:

  • previous CNC experience
  • previous design experience
  • types of projects you’ll be making
  • budget
  • and computer operating system

To give maximum flexibility, we made the LongMill MK2 software agnostic meaning it can accept input from nearly any software out there. Here’s an example:

  1. Dan has previous experience in graphic design and now he’s jumped into the world of CNC routers with the goal of engraving his designs onto nice wood slabs.
  2. He starts by creating his vector artwork in Adobe Illustrator since he’s had previous experience using it for graphic design.
  3. After having made the artwork, he opens it up in Carbide Create. He prefers Carbide Create because it’s an offline software that is easy to use and capable of v-carving, a great process for cutting intricate designs with a CNC.
  4. Once Carbide Create has made the machine code file, he opens it up in gSender. gSender is the software he uses to interface with his LongMill, allowing him to easily jog it around, set the origin point, perform probing, and he can use it to load and execute cutting files.
  5. Every time gSender completes a cutting file, Dan is now able to grab his completed artwork engraving off his LongMill!

In this example, Dan used three pieces of software in his software toolchain. This allowed him to start with a program he was comfortable with for the design aspect (Adobe Illustrator), then move on to a beginner friendly CAM software (Carbide Create), before finally running the generated code file using the machine interface program (gSender). This is just one software combination of many. To help you decide what software would work best for you we’ve done three things:

  1. Created a Toolchain Wizard which can provide you with smart recommendations after asking you 5 easy questions
  2. Compiled a list of programs that we’d personally recommend for the average CNCer
  3. Put every common CNC program into a Master Table (over 80!) that you can search and filter through if you’d like to comb through all the options yourself. This table is what powers our Toolchain Wizard 🙂

Our Recommendations

Many of our go-to software picks tend to be available for free and can range from beginner-friendly to more advanced. We also tend to more highly recommend software that is both Design-and-CAM-in-one since that helps to streamline the process of making projects on your CNC.

Remember that the design step in CNCing can be completely optional. If you’d like to browse a list of sites we put together where people share their CNC project designs either for free or for a price, click the button below. Half of the projects we’ve made ourselves have been off designs we’ve found online; feel free to leverage these resources in your own work with the right permissions.

Carveco Maker (link to site)

Carveco Maker is Carvecos entry-level product yet it comes with quite a bit of power. It has a lot of features similar to Vectrics Vcarve software such as standard toolpaths, 2D drawing, V-carving, and 3D importing but it can also create reliefs from 3D models and images and allows you to perform manual relief smoothing. This is a highly featured software that’s built for semi-professional CNC use and its capabilities reflect that. It’s also impressive how clean the user interface is when factoring in all the features it has.

CNC Interfaces

Many of our software picks don’t tend to have a built-in machine interface so we have a couple of independent programs that we’ve found work well. For most users, we recommend using gSender as the go-to interface software:

  • This is an open-source program developed by us, Sienci Labs, which you can download for free here:
  • We used to recommend highly some other senders, but hearing about their flaws we decided to make gSender as a solution to all the feedback we received
  • Detailed instructions on how to use gSender can be found here:
  • gSender is designed to work right out of the box for the LongMill MK2

The full list of GRBL-compatible senders is generally maintained here: but we’ve put together a more digestible list that you can reference below of the ones we’ve gone through and personally experimented with. All of these work well in most capacities and are easy to learn and pick up:

gSenderInterface1A reliable and lightweight sender based on CNCjs that’s easy to use and has novel expanded featuresAll desktopsFree
UGSInterface2A good default machine interface that’s lightweight but has good functionalityAll desktopsFree

gSender (

This software is designed to be clean and easy to use no matter your previous CNC experience. It has a variety of features such as macros, CNC calibration, surfacing, tool changing, and firmware control. gSender supports many GRBL-based machines and works out-of-the-box on the LongMill CNC.


Universal G-Code Sender (link to site)

This Java-based program comes in two forms: classic and platform. Classic is easier to use and pick up, Platform has many more features and is more configurable. The software is lightweight and reliable with a pendant available, and Platform additionally has customizable windows, a good spread of plugins, and easy macros.


CNCjs (

CNCjs can be built to run as a local web-app using Node.js or can be installed as a normal program onto your computer. It’s got lots of great features and functionality including surface probing and easy-to-make user macros. It’s got a pendant available and can be run on a raspberry pi.

OB Control

OpenBuilds Control (

Designed to work with Openbuilds CAM, it can still be used independently. Although it’s not as established as the other software on this list, it’s packed with some good features and is simple and colour-coordinated for improved ease of use. Pendant available.


Easel (

Extends through the Easel online software, allowing you to connect to your machine directly through your browser. It doesn’t have a lot going for it as it’s purposely limited to cater towards new users, but it’s usable and convenient if you’re already using Easel for design and CAM. The interface aspect has no difference between the Free and Pro versions of Easel.


VTransfer (

VTransfers barebones layout means that it’s dead easy to use and understand. The downsides to this is that it offers no gcode visualization, keyboard jogging, or other common interface features.


bCNC (

A python-based interface software and CAM utility. The main downside is that the software interface is very un-intuitiive and the getting the software installed isn’t beginner-friendly.

Source Rabbit

Source Rabbit (link to site)

This program is a modified version of UGS Classic with similar functionality and a modified layout, but with some of the added features that UGS Platform has. In some areas it’s been too far simplified that it reduces functionality, for instance the visualizer will only show g-code in the positive axes instead of showing the entire file.
