Zero-shaped display for zero-sized printers

ZeroD is an alternative firmware for the BTT Knomi V2 and other similar displays that replaces the network-reliant Moonraker connection with a direct serial connection to the Klipper host.

Installation

ZeroD firmware can be built and flahsed using PlatformIO.

An additional Klipper module is needed to enable the ZeroD configuration options, which can be installed by running the included install.sh script on the Klipper host.
