Upgrading Marlin 2.0+ with Mesh Bed Levling CR-10s

Download software

• Arduino: https://www.arduino.cc/en/Main/Software
• Marlin and configurations: https://marlinfw.org/meta/download/
  • You need the Marlin firmware in the “Downloads” column and the configurations from the “Configuration” column.

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>
