Board overview

The CNC310 is a CNC controller with USB interface, and is intended for 3 axes. However, the user can
upgrade the board through separate licenses with a 4

th

axis and activate the ethernet interface.

The image below shows an overview of the CNC310.

The purpose of the board is to offer a simple controller that can be used for operating small CNC
machines that need only limited I/O.

This document focusses on the hardware interface of this board, and how to use it to get a simple
CNC set up, up and running. This manual will only focus on the hardware part. For more information
about the software please check the software manual that can be downloaded from the website.
