If you want to run such powerful stepper motors, look into the Premium CNC GRBL controllers at the end of this list of controllers. The driving voltage is 12V with a maximum current of 2A, making it suitable for NEMA 17 or smaller motors but not ideal for larger NEMA 23/24 motors.
RATTM Motor operates at a voltage of 12-24V but is recommended to run at 24V. GRBL is an open-source CNC control platform/firmware that's highly popular for running hobbyist CNC mills and desktop CNC routers. It is compatible with Universal Gcode Sender (UGS) and can run GRBL 1.1. The RATTM Motor 3-axis GRBL CNC controller is a good value option for CNC engravers and laser engravers.

This article will also serve as a CNC controller board comparison guide for those overwhelmed by the choices available. I have chosen the best dedicated external controller for those control systems. Some of these control systems are PC-based motion controllers that turn the PC/Computer into a controller while others depend on a microcontroller to interpret the G-code.Įven for control systems that turn the PC into the controller (Mach3, LinuxCNC), there are dedicated CNC controller boards that do a better job than the direct parallel port. In this guide, I list the best CNC controllers available today for non-industrial CNC applications and provide a general review of each motion controller. Many features which were available only in industrial-grade CNCs are now available in hobbyist controllers too at an affordable price. While industrial CNC controllers were the only choice a decade ago, new technological advancements have revolutionized the hobby CNC space. The world of CNC Controllers has evolved considerably in the last two decades.
