Make sure that your machine is unplugged before performing modifications.

Removing the original Creality Motherboard:

Here's an easy to follow video guide made by Chris Riley, it shows you how to remove the old board and replace with a new one. You can disregard the part after the unit is powered on as we will be using a different procedure after installation. You may also omit using the ferules as shown on the video if you don't have them but it is highly recommended.

Ender 3 board removal by Chris Riley on Youtube

Here's a new video from Chris Riley showing the Kinetica G2-C on an Ender 3 and explaining some features of the board.

Preparing the board before installing it to your printer

Before installing the new board make sure to open up the green terminal blocks. You can do this by turning the screws counter clock wise until the clamp lowers to fully clear the opening. This ensure easy insertion of the wires.


Before removing the wires from the original board make sure that you label the wires to make it easier to plug them to the correct locations on the new board.

When Installing the wires to the Kinetica G2-C, use the wiring diagram to identify the connector placement as the layout is different from the original board.

Kinetica G2-C Wiring diagram 

It would be easier if the Wifi module and LCD adapter are installed before installing the board. You can leave the SD card and external antenna for later. It also might be easier to install the wires going to the green connectors before screwing down the board as it be a chore to get those wires in with little space to work with.

Start installing the Kinetica G2-C by aligning the SD card slot and USB connector to the opening on the metal case, then lower the board to match the mounting holes to the screw posts. Insert the screws but only tighten them once all the screws are in place. You may need to wiggle the board a little bit to get the best fit as the clearances are tight.

The Hotend Fan goes to the same location on the green terminal block connector, the fan for the electronics case (Top cover) goes to connector labeled "Case Fan" and the part cooling Fan goes to connector labeled "FAN 0". Please observe polarity when connecting the Hotend Fan.

Mount the LCD cable as shown below.

Install external antenna

The metal case of the Ender 3 weakens the Wifi signal of the module's onboard antenna, this can be solved by using the external antenna. It also has a higher gain compared to the on board one.

Lift the front of the Ender 3 and insert the antenna cable U.FL connector first into one of the bottom holes nearest the front of the case. Pull the cable up to connect to the Wifi Module. Align the round connectors together and slowly push the connector to snap on the board. Using a hard object like a flat screw driver to drive it down works better instead of your finger. Once latched on properly the cable should be able to rotate freely.

You can download the antenna holder STL on the support files page and print it.

Prepare SD card

An SD card is required to run the board. This is where the config files and Gcode files are stored. You can grab the zip files for the SD card here. 

Kinetica G2C support files

Copy all the folders to the root of the SD card.

If you have a stock Ender 3 Printer you can now insert the SD card and boot up the machine. If using any other machine or have a modified Ender 3 you would need to reconfigure some settings. To edit the config file open folder named "SYS" and open file named "config" on any text editor. 

The pre-configured access point is turned on by default, this allows you to quickly connect to your Kinetica board and use Webcontrol from any web browser as soon as it boots up. The Wifi SSID is KG2_WIFI and default password is 12345678. Once connected point your browser to IP to open  up the WebControl page. No need for USB to operate machine.

If you want to turn this off just comment out the line (by adding a semicolon in front of the line)

Plug in the SD card and double check all wires are in place before turning on the machine.
