Best Offline CNC Controller 2023

What is an Offline CNC Controller

CNC Offline Controller also called a stand-alone CNC controller, has the functions of a computer and CNC motion controller
It can work without connecting the motion control card to the computer. It only needs to remove the old control card and connect the drive directly to the offline controller.
The two types of CNC controllers are connected in the same way, but the offline controller eliminates the need to open the computer to read the tool path and work again. The offline controller has a G- that can directly read the U disk or TF card code file, some offline CNC controllers can take over the wheel.
The advantages of the offline controller are simplicity, convenience, and reduced interference. 

–> The following products are all solid choices. We’ve based these reviews on careful research, product comparisons, and user reviews, all to provide a comprehensive guide for buying a model that fits you best. 

Offline CNC Controller Software

Offline CNC controller software refers to computer programs or applications that allow you to control and operate a CNC machine without the need for an internet connection. These software solutions typically provide a user interface for designing or importing CAD/CAM files, generating toolpaths, and sending instructions to the CNC machine.

There are several offline CNC controller software options available in the market, and the choice of software depends on various factors such as the type of CNC machine you have, your specific workflow requirements, and your budget. Here are a few popular offline CNC controller software options:

Mach3: Mach3 is a widely used CNC controller software that supports a range of CNC machines. It provides features like toolpath creation, G-code editing, and manual control of the machine. It has an intuitive user interface and can be customized to suit different machine setups.

LinuxCNC: LinuxCNC is an open-source CNC controller software that runs on Linux-based systems. It offers powerful features, including real-time motion control, support for various hardware interfaces, and extensive customization options.

GRBL: GRBL is an open-source firmware and software package designed for small CNC machines, such as DIY CNC routers and 3D printers. It is lightweight and easy to use, making it suitable for hobbyists and entry-level users.

UCCNC: UCCNC is a commercial CNC controller software that provides a user-friendly interface and supports a wide range of CNC machines. It offers features like toolpath simulation, automatic tool change, and compatibility with various motion control hardware.

Autodesk Fusion 360: While primarily known as CAD/CAM software, Fusion 360 also offers offline CNC controller capabilities. It allows you to design and simulate your parts, generate toolpaths, and export G-code to control your CNC machine.

It’s important to note that some CNC machines may come with their own proprietary controller software, so it’s recommended to check with the machine manufacturer for compatible software options.

Before choosing a specific offline CNC controller software, consider your machine’s compatibility, the features you require, the learning curve, and user reviews. It’s also advisable to download trial versions or demos, if available, to evaluate the software’s suitability for your needs.

Offline CNC Controller vs PC


1, Offline and convenient and intuitive, similar to the operation of the machining center
2, If you do a lot of duplicates, offline is more convenient, I used to use a notebook, and I have been charging all the time, more trouble
3, Support power-off continuous carving function
4, Offline stability it is easier to operate than mach3


CNC Offline Controller does not support the network. This is the worst. If there are many machines, use a computer and share a disk. Everyone is going to read the knife path. It is more convenient than using a USB disk. It is fast. , the version is easy to control, and the U disk is also easy to break.

The price of an offline CNC (Computer Numerical Control) controller can vary depending on various factors such as the brand, features, specifications, and capabilities. It’s important to note that prices can change over time, so it’s best to check with manufacturers, suppliers, or retailers for the most accurate and up-to-date pricing information.

To give you a general idea, offline CNC controllers can range from a few hundred dollars to several thousand dollars. Basic controllers with limited features and capabilities may be available at a lower price point, while more advanced controllers with advanced functionalities and compatibility with various CNC machines may be priced higher.
