[How to enter the world of Tinkergnome firmware?]

On Cura version 2.1.3, I simply swaped the shipped firmware with the firmware i wanted to get flashed.

In my case, i'm using OSX and the Cura app comes with a directory containing the firmwares:

/Applications/Cura.app/Contents/Resources/cura/resources/firmware/

 

I wanted the latest tinker firmware fetched here.

Simply replaced my version of the firmware for my machine:

 

1. Make a bakup of the shipped firmware:
   

   $ mv /Applications/Cura.app/Contents/Resources/cura/resources/firmware/MarlinUltimaker2plus.hex /Applications/Cura.app/Contents/Resources/cura/resources/firmware/MarlinUltimaker2plus.hex.backup

   
    
   

2. Copy our new firmware to replace the shipped firmware:
   

   $ cp -v  ~/Downloads/Tinker-MarlinUltimaker2plus-*.hex /Applications/Cura.app/Contents/Resources/cura/resources/firmware/MarlinUltimaker2plus.hex

   
    
   

3. Update the machine using Cura:
   Cura > Extentions > Firmware > Update Firmware
