Before you begin on your journey, a word of caution.
In the comfort of your own home, you are about to assemble a robot. This machine can maim, burn, and electrocute you if you are not careful. Please do not become
the first VORON fatality. There is no special Reddit flair for that.
Please, read the entire manual before you start assembly. As you begin wrenching, please check our Discord channels for any tips and questions that may halt your progress.
Most of all, good luck!

THE VORON TEAM

FOREWORD

• Why another board?
• There was a time when the boards available on the market were either unreliable or just too feature-rich.
• This gave Voron the idea to create their board.
• The target was to implement only the essential functions that a Voron printer needs (maybe it turned out to be a bit more in the end).
• It quickly became clear that not everyone can build such a board themselves.
• So they looked for a partner who could take on this task and also offer it on the market.
• This is how the cooperation with LDO came about.
• At LDO it would also fit well into the portfolio with the existing kits.
• So the way was clear for both sides.
• Thus the project Leviathan was born.
• Sincerely! JNP

CONTROLLER BOARD OVERVIEW

PREPARATION

CONTROLLER BOARD

• The manual will outline the wiring for a Leviathan V1.2 board. You can find additional documentation and alternative configurations on docs.vorondesign.com

JUMPERS

• Several jumpers need to be configured on the controller board. Begin by removing all the JUMPERS from the controller board (MCU).

1. Remove the jumper in the “Probe Voltage Selection”
2. Remove all the jumpers on the “Fan Voltage Selection”

FIRMWARE

PREPARATION:

• The board can be flashed via USB with the STM32 CubeP programmer. (https://www.st.com/en/development-tools/stm32cubeprog.html)
• The board can be put into the necessary DFU mode using two switches.
• To do this, connect the board to the PC using a USB-C cable.
• Then press the reset (SW1) and boot (SW2) switches at the same time. First release the reset switch, then the boot switch. DFU mode is activated.
• Firmware can now be flashed via STM32CubeProgrammer.

BOOTLOADER:

• Catapult (CanBoot) is recommended as a bootloader.
• The necessary settings can be seen in the picture.
• https://github.com/Arksine/katapult .

KLIPPER

• Leviathan is supported by Klipper firmware.
• With the bootloader, the Klipper firmware can be flashed directly via the RPi. See also: https://www.klipper3d.org/Installation.html#building-and-flashing-the-micro-controller

CAN Interface:

• If you want to use the CAN bus interface, Klipper must be configured as a USB to the CAN bus bridge. Necessary settings can be seen in the picture.

USB Interface:

• If you want to use the USB interface only, Klipper must be configured as seen in the picture.
