If you like this post processing script, consider supporting me :)

Note: This is a lite version of the ElegooNeptuneThumbnails plugin for Cura 5.X. For all features, use Cura :)

PrusaSlicer post processing script for adding gcode thumbnail images for Elegoo Neptune printers. The following models are supported (for other models, see FAQ):

• Elegoo Neptune 4
• Elegoo Neptune 4 Pro
• Elegoo Neptune 4 Plus
• Elegoo Neptune 4 Max
• Elegoo Neptune 3 Pro
• Elegoo Neptune 3 Plus
• Elegoo Neptune 3 Max
• Elegoo Neptune 2
• Elegoo Neptune 2S
• Elegoo Neptune 2D
• Elegoo Neptune X

Note: If you have some idea on how to improve the post processing script or found a bug, feel free to create a GitHub issue for that

1. Download the post processing script binary for Windows from GitHub if you are using another operating system, you have to compile the script yourself as described in Packaging Guide
2. Place the binary somewhere on your system and remember the path ( e.g. C:\Users\Michael\ElegooNeptuneThumbnails-Prusa.exe)
3. Set the thumbnail generation in PrusaSlicer to 600x600 PNG
4. Configure the path to the post processing script binary in PrusaSlicer
5. If it isn't working, check the FAQ

Yes, check out the ElegooNeptuneThumbnails plugin for Cura 5.X, which is the extended version of this pos processing script.

The script cannot auto-detect your printer when doing so. To manually set the printer model, use the parameter --printer=<printer_model> after the path of the processing script in the PrusaSlicer settings. It should look like C:\Users\Michael\ElegooNeptuneThumbnails-Prusa.exe --printer=NEPTUNE4PRO. Allowed values are the following:

NEPTUNE4, NEPTUNE4PRO, NEPTUNE4PLUS, NEPTUNE4MAX, NEPTUNE3PRO, NEPTUNE3PLUS, NEPTUNE3MAX, NEPTUNE2, NEPTUNE2S, NEPTUNE2D and NEPTUNEX

The "normal" Neptune 3 doesn't support displaying thumbnails, I have talked with Elegoo as there were many people asking for it.

Make sure, that you have followed the installation steps correctly.

There seems to be a bug in older printer firmware versions which causes the thumbnail to not update if you start a print right after the last one ended. Restarting the printer in between prints seems to fix that. If this is the case for you, check your printer for firmware updates, which might fix the bug.

Unfortunately I am dependent of the official Elegoo Cura binaries and as there are no binaries for the MacOS M series chips, I am not able to provide support for those.

If you have an arm64 mac, you will need to build an executable inside of a x86_64 python environment. The easiest way is with miniconda:

conda create -p ./my_x86_env -y
conda activate ./my_x86_env
conda config --env --set subdir osx-64
conda install python=3.11 -y

Then, follow the steps for other systems.

1. Install requirements pip install -r requirements.txt

2. Create binary for your system

   Windows:

   pyinstaller --onefile --add-binary="libs/ColPic_X64.dll;libs" --add-binary="libs/libColPic.so;libs" --add-binary="libs/libColPic.dylib;libs" --name="ElegooNeptuneThumbnails-Prusa" elegoo_neptune_thumbnails.py

   Mac/Linux:

   pyinstaller --onefile --add-binary="libs/ColPic_X64.dll:libs" --add-binary="libs/libColPic.so:libs" --add-binary="libs/libColPic.dylib:libs" --name="ElegooNeptuneThumbnails-Prusa" elegoo_neptune_thumbnails.py

3. Binary is in dist folder
