  • OctoPrint
  • OctoPrint-E3S1PROFORKBYTT_Thumbnails plugin
  • with one of the printdata postprocessing scripts sliced gcode
  • printer connected to OctoPrint
  • sd card in the printer for temporary file storage of the thumbnail.

Appendix 1: Printing from Slicer

It is only possible that the thumbnail is transferred if you dont start the print from your slicer directly. You can transfer it to the printer over the slicer but need to load and start the print manually.

1.) if you slicer transfers it only it is ok. then you select it and press print.

2.) if you slicer transfers it and selects it is ok. then you press print.

3.) if you slicer transfers it, selects it and starts the print it is not ok and won´t work.

Appendix 2: Temporary files that are created during thumbnail upload

Two files are created on the sdcard and directly delete after the thumbnail transfer to the display. So dont have files on the card that are called "OCTODGUS.GCO" or "TEMP.GCO". Both will be overwritten and deleted.
