• Firmware

• All file names are lowercase.
• Underscores (_) are used to replace spaces.
• Organizational folders are prefixed with an underscore (_).

NOTE: The Ender 3 Pro looks for .bin (or .BIN) files/folders in the root and will attempt to update the firmware using them.

The printer_export.sh file can be used to copy the prints folder to an external drive (micro SD card).
I recommend using Git Bash. :)

NOTE: Git Bash seems to automatically create a $RECYCLE.BIN file when deleting files. A check was added to delete this.

NOTE: The destination folder will be WIPED before the copying occurs. Be careful!!!

• The first argument is a source folder, and the second is the destination.
• The folder structure is maintained.
• Only the .gcode files are copied over.

Example command (assuming the removable media is the D:\ drive):

sh printer_export.sh prints /d/
