Help with ender3 pro

My ender 3 is not reading the SD card. It did but I reformatted due to new files being added and machine said to reformat disk. Now it’s not reading anything. Please help.

Also can you download creality files instead of using bambu. As id like to use my flashforge ad5x

Make sure to use a microSD card up to 32GB (avoid bigger SDXC cards on older machines like that) and format it in FAT32.

The files the printer uses are sliced .GCODE files. They should be sliced for your machine not for a BambuLab or Flashforge printer of course. But you can download the STL or 3MF from the Bambu Makerworld website and use the slicer to slice it for your Ender 3 Pro of course.

Have you tried a new SD card. In my experience the one that comes with the printer is poor quality and soon packs up.
