Updating the Configuration files involves copying the new versions of the configuration files to your M3D Crane Series printer's SD card. You will need an SD card reader in order to update the configuration files using this method. Be sure your M3D Crane Series printer is powered OFF before removing the SD card. The Configuration files that must be updated are /sys/, /macros/, and /menu. You may wish to back up your /macros/ in order to prevent any gcode files, slices, or macros you wish to save from being overwritten during the update process.
