STEP 1: Start by making a backup of the existing installation:

Make a backup of the configuration and file installation. We recommend creating a backup of the current installation by right-clicking in the current installation folder and zipping it.

STEP 2: Set up Bluetooth configuration.

STEP 4: Download the Screen with its components and macros.

Download the compressed file containing the macros and the screen that works with the macros:

You will need to install the screen found in the download folder and place the macro in the macros directory for the profile folder.

 
Make a backup of the original M3 and M5 macros by zipping them into the same folder, just so you may have access to the original macros if you need to revert the installation later.  Then replace the M3 and M5 macros for the profile you are configuring: 

STEP 5: Configure the new Plasma Screen:

Set UCCNC to use the new screen that you just copied:
