Once you have your Ender 3 pro up and running, you’ll want to plan out your upgrade path before taking it apart. At the very least you’ll need an adapter to mount the Duet 3 Mini 5+ board in the Ender 3 electronics enclosure. Download link:

You also have the option of replacing the enclosure entirely with something of your choosing. There are a few printable enclosure options on Thingiverse. Though if you go this route, you may need to extend some of the wiring.

Next, go through the LCD menu and record certain details about the firmware settings, mainly axis length, steps per mm, acceleration, max speed, and jerk settings. This will be required when we use the RepRapFirmware Web Configurator to prepare our starting configuration files.

See here for a more detailed breakdown of what information is required and how to obtain it: Adapting an existing printer to Duet

Most of this information can also be found in the Marlin Configuration.h file. Your SD card from Creality may contain the Marlin files, and it can be downloaded from the Creality website or GitHub repository. Download link:

The 3rd photo shows the planned wiring connections we will be making. This will be a handy list when it comes time to create the config file using the online tool.
