How to Enable G-Code Thumbnails in Your Slicer

Most 3D printing slicers allow the ability to include preview thumbnails that can be shown in the Obico mobile and web app, as well as Mainsail and KlipperScreen.


Obico shows thumbnails only for G-Codes, uploaded directly to the app. If you explore OctoPrint/Klipper files, you won't see file previews.

Each slicer handles thumbnails differently. Select the slicer you use below to enable thumbnails.

  1. In Expert Mode, select Printer Settings

  1. Under the Thumbnails section, enter 32x32 for Small and 400x300 for Big. You can further customize your thumbnail's look in SuperSlicer as well.
