Mainsail can display thumbnails in the file browser and as previews in the print status.
In “Expert” mode PrusaSlicer has an option in the “Printer Settings” tab to activate previews. Under
General / Firmware, enter
32x32,400x300 as “G-code thumbnails”.
In “Expert” mode SuperSlicer has some very convenient options in the “Printer Settings” tab to activate and customize the previews.
To enable thumbnails, click on
Help > Show Configuration Folder and navigate to your printer profiles inside the
printer folder. Open your printer profile in a text editor and find
thumbnails = and add the resolutions
32x32,400x300. Save the file and restart your Slicer.
From now on the gcode files contain thumbnails displayed by mainsail.
The Cura plugin “Cura2Moonraker” is required for this. You can find this plugin and a install guide here: https://github.com/emtrax-ltd/Cura2MoonrakerPlugin
