mrcz's Anet A8 custom build config

Updated to Marlin 2.0.5.3

Requirements

• A working Anet A8 printer to begin with
• Internet connection
• A working computer (tested on Windows 10 2004 build)

Resources

• Download Marlin 2.0.5.3 source code here
• Download Marlin 2.0.5.3 board configurations here
• Download Anet A8 board definition for Marlin from master branch here
• Download Arduino here

Setup Steps

• Install Arduino IDE
• Copy Anet A8's board definition adr you can find under anet-board-repo-folder/hardware to the Arduino/hardware system application folder (on Windows should be C:\Program Files (x86)\Arduino\hardware)
• Run Arduino IDE and go to Tools -> Board and set Anet V1.0 as your board definition for code compilation
• Copy all the board configuration files from Configurations-2.0.5.3\config\examples\Anet\A8 to Marlin-2.0.5.3\Marlin and override existing configuration files if asked to do so
• Open C:\Program Files (x86)\Arduino\hardware\anet\avr\platform.local.txt compile configuration file and add the following entries:

compiler.c.extra_flags=-fno-tree-scev-cprop -fno-split-wide-types -Wl,--relax -mcall-prologues
compiler.cpp.extra_flags=-fno-tree-scev-cprop -fno-split-wide-types -Wl,--relax -mcall-prologues
compiler.c.elf.extra_flags=-Wl,--relax

Building Marlin for Anet A8

• Open Marlin-2.0.5.3\Marlin\Marlin.ino file project and select the proper Anet V1.0 board definition for compiling
• Click on Verify to start compiling Marlin firmware (it should take some time, don't worry)
