Remove all the jumpers on the board before starting. Insert the jumpers onto the highlighted pins.

UART mode - placing these jumpers will allow for tuning and controlling options on the printer interface.

USB-C Power option - with this jumper the board can be powered via USB-C. This will allow you to compile and download the firmware directly to the motherboard using DFU mode, ideal for testing the board.

Voltage Selection - Each fan output can be set to one of three different voltages (5V, 12V or 24V) depending on the jumper positions. The third image exemplifies where the pins must be placed to achieve different voltages.

The voltage selections used in the guide are for the electronics kit provided by Rat Rig. If using different fans, ensure the voltages are set correctly to avoid damage to components.

Bed Heater with the incorporated Thermistor.

Do not mistake the bed heater wires for the bed thermistor wires. The thermistor wires are the ones with the JST 2 wire connector.

The thermistor is a resistor that strongly varies with temperature. When connecting a resistor you don't have to worry about cable order as resistors don't have polarity.

The magnetic sheet and heater pad will be installed later during the commissioning guide. Do not install them now.

Connect the Bed Thermistor to the first thermistor slot, counting from the bottom.

Place the heater pad next to the machine and connect only the thermistor

This is required to follow the guide and perform a sanity check

21x Electronics Wire Guide Clips

Click them into place once all the cables are routed inside of the Electronics Wire Guides.

Close the clips carefully as you might pinch/break the cables.

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.

Click here to access the V-Core 4 Main wiring diagram. This will guide you through the Installation of the IEC and high voltage circuit

Warning for users in countries with 110V Mains

Before connecting the power cable, inspect its rating. Ensure the cable is labeled with the correct voltage and current ratings for your electrical installation. If you are uncertain about which power cable to use, seek advice from a certified electrician. Rat Rig recommends using a power cable rated for 20A.

Cable Sleeve - Black 9.5mm split braided sleeve

Route the sleeve along the piano wire and hide the cables+piano wire inside of it.

Insert it on the electronics enclosure for a cleaner look!

Use zip ties to secure the umbilical to the toolhead and frame.

TIP: Use zip ties to secure the PTFE tube to the wiring sleeve for a cleaner look. Do not stretch the PTFE tube, as this can cause the filament to bind inside and reduce the machine's performance.

This step is optional, this sleeve will enhance the stealth look of your machine, at the cost of not being able to see the filament inside the PTFE tube.

Cable Sleeve - Black 4mm split braided sleeve (SCW-003)

Carefully wrap the PTFE tube with the smaller 4mm braided sleeve, for a stealth look!

It's known that if you subscribe to Rat Rig TV and use the PTFE sleeve, your V-Core 4 will increase its acceleration by +50k mm/s2!
