6 Best CNC Control Packages in 2022

CNC control packages have evolved significantly in the last ten years. 

 

Earlier, industrial CNC controllers were the only choice available. However, with more hobbyists and small-scale machinists taking over production tasks, CNC controllers have evolved to simplify the hobby CNC space.

 

Many features available in industry-grade CNC control packages are now finding their way in CNC controllers for hobbyists.

 

In this article, we will review the best CNC control packages in 2022.

 

But before we get into that, let’s first understand what CNC controllers are and how do they work. This will help you better understand your machine and find the right controller for it. 

 

What are CNC Control Packages?

 

CNC stands for Computer Numerical Control, which only goes on to say that controlling is one of the primary functions of the machine. A CNC controller could be called the brain of the CNC machine. It is where the information gets in and is transformed into meaningful results.

 

A CNC controller connects the CNC machine with a computer, allowing you to put the desired data into the computer and get the machine to materialize something out of it. 

 

For instance, the brain receives and interprets external stimuli through sensory signals. Similarly, a CNC controller interprets signals from a computer and passes them to the machine to function specifically.

 

A CNC controller uses G-code to send the signals to the machine’s motors, getting it to perform certain tasks. 

 

CNC controllers can be broken down into two basic parts: the physical board and its software. Different controllers come with different software. Some manufacturers offer proprietary software with their controllers, while others come with third-party software. 

 

CNC controllers serve three main functions:

 

Axis Control: CNC controllers can control several axes at the same time, allowing for seamless machining.

 

Interpretation: CNC controllers also interpret the signal sent from the computer and translate them into signals that the machine understands.

 

Interpolation: Interpolation is the governing factor that actuates the movement of the trajectory. A CNC controller matches the data sent by the computer with the machining speed and accuracy. 

 

Types of CNC Controllers

 

CNC control packages can vary depending on the industry and the nature of the application. Broadly speaking, you can categorize them into three types:

 

Motion Control

 

Motion control is the most basic form of a CNC machine. A CNC controller helps provide automatic, precise, and consistent motion control in CNC machines. Each CNC machine comes with at least two directions of motion: the X and Y-axis. 

 

Generally speaking, CNC controllers determine the motion type (rapid, linear, circular), the axes to move, amount of motion, and motion rate using the signals from the computer.

 

Loop Control

 

These CNC controllers loop mechanisms to execute certain tasks. These types of controllers can further be classified into open-loop and closed-loop systems. In an open-loop control system, the controller transmits the signals through the input device. In a closed-loop control system, the system also collects feedback from the control system.

 

Axis Control

 

Axis control CNC controllers are designed specially to control various axis movements in the machine. These CNC controllers come in various configurations from two-axis (X and Y) to 5 axes (X, Y, Z, A, and B). 

 

Microcontrollers

 

Microcontrollers are self-sufficient controllers. They are tiny controllers with a small circuit board that run without a computer. These controllers are also known as plug-and-play because you can practically plug them in and out of your machine any time you want without having to shut down anything. 

 

There are also CNC retrofit controllers, which are used to convert manual machines into CNC.

 

Now that we have learned about the CNC controllers and their type, let’s take a look at the best CNC controllers in 2022:
