Klipper is a 3d-Printer firmware. It combines the power of a general purpose computer with one or more micro-controllers. Details can be found from https://www.klipper3d.org/
This configuration is mainly for AM8 (Anet A8 metal frame upgrade) but it should work with Anet A8 on SKR v1.3 mainboard.
Note: Depending on your bed position you should specify position_endstop: value for both X and Y.
# This file contains common pin mappings for the BIGTREETECH SKR V1.3
# board. To use this config, the firmware should be compiled for the
# LPC1768.
