Config for Geeetech A series printers: A10, A10M, A10T and
A20, A20M, A20T. Based on few configs found on the discourse forum, facebook groups. In addition, using official schematics from: https://www.geeetech.com/download.html https://github.com/Geeetech3D/Diagram/files/8199212/GT2560V4.1BSCHA20T.pdf Contains macros for filament mixing based on: https://klipper.discourse.group/t/mixing-color-support/2246/12 https://klipper.discourse.group/t/mixing-hotend-m163-emulation/11423/2 Signed-off-by: Alexander Bazarov <[email protected]>
