I do not understand why I can not bring up the files on the SD card on my Bambu studio software. I can only bring it up on the printer screen with no image and no way to make changes.
If you mean the sliced files that came preinstalled - they are already sliced into gcode (code for the printer).
What you would need are the original stl or stp files from where does were generated in the slicer (Bambu Studio)
