Setting up your firmware on the Kossel

The firmware can be found on the google drive link along with the build guide.
You will need to install the Arduino IDE which can be downloaded for free from If your kit uses the RAMPS 1.4 controller, you will have a 'Mega 2560' board.

By default the code has been setup to run the 2004 LCD, but you do not need the LCD to run the code.

You will need to adjust the following settings in your firmware that are custom to your build:
-Rod length

-Z Height

-Auto-tune probe offset

These settings are all located in the configuration.h file.

Details of this can be found in the config guide.
