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.
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.
