Regardless you own a CNC milling machine, lathe, or plasma cutter, you require a motion control system to direct the motions of your CNC machine. And this system is provided by a CNC controller.

A CNC controller connects your computer with the mechanical components of your CNC machine and performs accordingly to print a certain design or a pattern on sheets. So fair enough to say that the CNC controller is the brain of your CNC applications.

It is also interesting to learn that the CNC controller consists of several other peripherals such as stepper motor drivers, power source, power controls, software, and firmware. These components work together to direct the motion of your CNC machine in certain directions, also called axes.

A 3 axes GRBL controller is the most widely CNC controller used by machinists for their CNC machines. It is fairly simple, more adaptable, and compatible with standard OS versions.

Owing to this, we have listed the best 3 axes GRBL controllers you can consider for your CNC machining requirements.


Here are my recommended products picked out through amazon you would be interested in depending on your budget…
