Load up printer-specific configurations

In the Configurations navigate to config > examples > Creality > CR-10s and copy-paste the files into the Marlin-2.0.x > Marlin folder. It should prompt you to overwrite the existing Configuration.h and Configuration_adv.h files.

Load up the firmware

Run the Marlin.ino file from the Marlin folder. It should open up the Arduino IDE with the Marlin, Configuration.h, Configuration_adv.h, Version.h, _Bootscreen.h, and _Statusscreen.h files.

Select the correct Arduino boards

  • Tools > board > Arduino Mega or Mega 2560
  • Tools > processor > ATmega2560 (Mega2650)

Make edits to firmware files

See here for the changes I made: https://github.com/chendaniely/3d-printer/pull/1

The relevant configurations you’d want to make for manual mesh leveling are:

  • Disable auto bed leveling bilinear: //#define AUTO_BED_LEVELING_BILINEAR
  • Enable mesh bed leveling: #define MESH_BED_LEVELING
  • Enable restore mesh: #define RESTORE_LEVELING_AFTER_G28

If you are upgrading Marlin you’d also want to enable EPROM auto init: #define EEPROM_AUTO_INIT

Flash the firmware

  • Plug in your printer
  • verify

If you run into any errors, this is a good video walkthrough of potential issues: https://www.youtube.com/watch?v=lAKyZd63_ns

I was having an error around #include <U8glib.h>


Scroll down to “U8glib for Arduino”

Download the library, and then in the Arduino editor Sketch > Include Library > Add ZIP library
