¶ Mains Power
This guide covers the AC wiring for the UCEE. Before proceeding with any AC 230V wire connections, it is crucial to understand the risks involved. Alternating Current (AC) at 230V / 110V is a high voltage that can cause severe injury or even death if not handled correctly. This type of electrical work is highly dangerous and should only be performed by a licensed professional. By using this guide, you acknowledge the following:

¶ Firmware
Here you will find all the configurations and instructions needed to get your machine operational with the firmware we officially support, such as FluidNC for the Rodent controller (GrblHAL coming soon) and UCCNC for the AXBB controller.
¶ FluidNC
FluidNC is a CNC firmware optimized for the ESP32 controller. It is the next generation of firmware from the creators of Grbl_ESP32. It includes a web-based UI and the flexibility to operate a wide variety of machine types.
¶ Configuration Guide
A step-by-step configuration guide is now available. It covers the installation of FluidNC on the Rodent board.
- Start by connecting the Rodent via USB to your computer. Go to the FluidNC web configuration tool — click here. Click on the connect button (1). Your browser will ask permission to connect via USB Serial to the right COM port, allow it.
- If the right COM port is selected, the browser will start establishing connection to the controller.
- As soon as the connection is established, you will access the FluidNC installer tool. Proceed to click "Install FluidNC" (2), as shown below:
- Ensure the latest official release is selected (3), then click the blue button to install FluidNC on your controller (4).
- Click "wifi" (5) followed by "fresh-install" (6), then select the 115200 baud option (7) and finally click "install" (8).
- FluidNC will be installed on your controller, wait for the installer to finish then click "continue" (9).
- An error will appear stating that FluidNC wasn't able to find a config — we'll upload it in the next steps.
- Click on the "Upgrade FluidNC" button (10).

¶ How to Install UCCNC
Installation:
- To install the license key simply unzip and copy the files you will receive to the UCCNC directory, connect your UC100/UC300/UC300ETH/UC400ETH/AXBB-E motion controller to the USB/ethernet port and run the software.
- License key: after buying a license key, please reply to your order confirmation e-mail with the serial number of your controller. We will provide you with the correct key for that specific serial number.
- The latest software version can always be downloaded from: https://cncdrive.com/UCCNC.html
- Please feel free to register and post on the CNCDrive forum at: https://forum.cncdrive.com
- For customer support about the software, email: support@cncdrive.com
Note: The UCCNC software is licensed per motion controller. One license key works with one motion controller only. The license keys are tied to the serial numbers of the motion controllers and are not tied to the computer in any way, which means that the license keys can be installed on any number of computers.
