Wonderful board

Great board for printers for ants (West 3D’s micron plus would be a perfect fit for this board). Currently using it on a Voron 2.4 and it works great. Easy setup and great flashing / instructions from LDO motors. Pinout is even screen printed on the board so you never have to look up the pins.

Great Controller Board

Great documentation, easy to setup in minutes, and built in power for pi. Ready for 48V gantry if I ever go that route.

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 own board.

The target was to implement only the really 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.
