Description

K-touch with Firmware 1.1.0 installed is not recognising the thumbnails wether it's set for 100x100 PNG, 200x200 PNG or 300x300 PNG as recommended, when slicing gcode from PrusaSlicer, PrusaSlicer BOSS (https://github.com/mjonuschat/PrusaSlicer/releases/tag/version_2.9.0%2Bboss) or SuperSlicer.

I've tried out OrcaSlicer, which seems to work.

Could the firmware be configured to work with the other slicers as well?

I've uploaded a PrusaSlicer BOSS gcode file and a OrcaSlicer file to show you the difference/similarities.

Research direction

Start with the attached Gcodes.zip and compare the PrusaSlicer BOSS and OrcaSlicer files, focusing on how their thumbnail data is represented. Trace the firmware's thumbnail-recognition entry point from that difference. Done means K-Touch recognises the documented 100x100, 200x200, and 300x300 PNG thumbnails from PrusaSlicer, PrusaSlicer BOSS, and SuperSlicer.
