Rat RIg Universal CNC Electronics Enclosure
The Rat Rig Universal Electronics Enclosure was designed with plenty of room to house the electronics of any CNC machine, from Rat Rig or not!
Compatible with the Rat Rig preset beginner, intermediate, and advanced electronic bundles, it features pre-drilled mounting points for popular controllers like Rodent, AXBB, Scylla, and Flexi-HAL controller boards.

Flexible mounting options
The Universal Electronics Enclosure supports all our preset electronic bundles, beginner, intermediate, and advanced with pre-drilled plates for Rodent, AXBB, Scylla, and Flexi-HAL controllers.The plates being made of aluminum, not only provide grounding for the entire enclosure but also offer flexibility for custom setups. If you prefer using your own components, the kit includes three long DIN rails, allowing you to mount your electronics with freedom and flexibility.

Safety Features
Features an IEC socket with a safety fuse, start/stop buttons, and a contactor that isolates the 220V circuit, protecting the user from high voltage and preventing automatic restart after power loss.

Cable management
AC and DC circuits are fully separated for safety, with industry standard color coded wires for ground, neutral, and live. Modular PTfix distribution blocks, also color-coded, are used to organize cables neatly.

Magnetically latched door
The Universal Electronics Enclosure includes all panels, with one featuring a magnetically latched door. It also comes with two 120mm fans and a dust filter to keep electronics cool and prevent dust buildup inside.

Printed parts
Check our github to get access to STL files for all printed parts. All files are provided in the correct orientation for printing on a standard FDM 3D printer. In general the printed parts are quite forgiving, but are also quite large. If you suffer from drafts and/or poor bed adhesion you may need to use brims/rafts for some parts to prevent warping.The following table shows the recommended print settings when printing any of the parts provided.
Print Settings:
- Perimeters
- 4
- Line Width
- 0.45mm
- Layer height
- 0.2 - 0.3 mm

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:
Rat Rig CNC machines - 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.
Select your firware of choice:
Fluid NC
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 to 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 permition 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 to click "continue" (9).

An Error will appear, stating that FluidNC wasn't able to find a config, we'll upload it on the next steps.

Click on the "Upgrade FluidNC" button (10).

Click on the "upload" button (11) and upload the correct file:
Then check if the new config file is "active" (12)

If you have any config erro, reboot the board, the error should go away.
Navigate to the "wifi" (13) page and fill all the details with your network if you desire. Also fill the Access point settings, as the Rodent will use it's own wifi if it fails to connect.

Reboot the board and acess it via your browser RatRigMill.local
UCCNC
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 you may always download and reach on the following webpage: https://cncdrive.com/UCCNC.html
