CNC USB MACH3 100KHz Breakout Board

Upgrade your CNC projects with the CNC USB MACH3 100KHz Breakout Board – a plug-and-play, 4-axis motion controller that offers stable and responsive control of stepper drivers using the widely-used MACH3 software.

This board replaces the old-fashioned parallel port interface with a high-speed USB connection, allowing you to use modern PCs or laptops for your CNC router, laser cutter, or engraving machine. It supports up to 4 axes (X, Y, Z, A) and provides 100KHz pulse frequency output, enabling precise and smooth motor movements when paired with stepper drivers like TB6600 or TB6560.

With features like isolation protection, emergency stop input, and manual spindle control, this breakout board is a reliable core for any CNC setup. It’s a must-have for both beginners and professionals building their own motion control system.

✅ Key Features:

• Interface: USB to 4-axis stepper driver

• Pulse Frequency: Supports up to 100KHz for smooth motion

• Software Compatibility: Fully supports MACH3 CNC

• Axis Support: 4 axes (X, Y, Z, A) for complex CNC setups

• Output Pins: Step, Direction, Enable signals

• Additional Inputs: Emergency stop, probe, limit switches

• Power Supply: USB-powered or external 5V

• Signal Isolation: Optical isolation for safer operation

Setup Instructions

Step 1: Installing Mach3: You will need to purchase a Mach3 license and download the software. If you already have a licensed copy of Mach3 skip this step.

Step 2: Download the USB Motion Driver RnRMotion.dll from the link above and copy and paste the file into your Mach3 Plugins folder Example: “”C:/Users/ProgramFiles/Mach3/Plugins””

Step 3: Make sure you board is connected to the PC via USB cable. It should automatically recognize the USB device.

Step 4: Open Mach3 and you should be prompted to select a driver. Select the “”RnRMotionController”” and check “”Don’t ask me again””. This will allow your board to communicate with Mach3.

Step 5: Download the XML Mach3 Config File above by right clicking on the link and selecting “”save as””. Save the Mach3Mill.xml file in your Mach3 root folder.

⚠️ Precautions:

• Ensure correct wiring of step and direction signals to drivers

• Install MACH3 software and configure COM settings before use

• Avoid static electricity while handling the board

• Use shielded USB cables for optimal signal integrity

• Do not exceed the maximum step frequency per axis
