Lerdge Z Board w/ screen

Replacing a 3D printer controller board can be a daunting process. Pairing your specific hardware to open-source firmware like Marlin requires setting up the firmware and code compilation. Although the process isn’t that hard, it can be complicated for some users.

The Lerdge-Z controller board aims to simplify the setup process as much as possible. All the firmware setup is done directly at the touchscreen display of the printer, so no coding or compiling is required. This board is compatible with different 3D printing setups, including CoreXY and delta printers.

Replacing the older -X and -K models, the Lerdge-Z runs with a 32-bit processor and offers compatibility with TMC drivers (although lacking UART and SPI support). This controller board, however, requires its own matching 3.5-inch touchscreen display to work properly.
