Elegoo Neptune 2 firmware source code 🔱

This firmware will work on the 1.0.3 version of the Neptune 2 only.

This is the firmware source code that Elegoo support provided for me when I asked after some of the Marlin features that where not turned on in the stock version.

It seems that it is not 100% stock as the TFT images and options are different, however it does compile and run on the MKS Robin Nano main board that the printer uses.

This project is not completed. Here is a todo list.

Disclaimer

This firmware comes with no warranty or support, use at your own risk.

Todo:

• Create video explaining both build options

Building

2. Edit any settings you want in the firmware, you can do this by pressing the period key (.) in your browser when you have your forked repo open
3. Stage, Commit and Push your changes
4. Go to the actions tab in your forked repo
5. Watch the build finish 🤞
6. Download the firmware in a zip file from the artifacts
7. Place the firmware files on a SD card
8. Insert the SD card into the printer and reset it

Option 2 - Local build

Requirements

1. Git
2. Vscode
3. PlatformIo extension
4. Marlin Auto Build extension

Process
