This flashforge is similar to the Anycubic Kobra 2 Series. So we need to investigate it.

Usage

1. Clone the repository.
2. Place .bin, .zip or .swu firmware files in the FW directory. If you don't have firmware files, you can use the script fwdl.sh <model> <version> to download in the folder FW the version for the printer model you need. The supported models are K2Pro, K2Plus and K2Max. The version is given in the format X.Y.Z like 3.0.9.
3. Run unpack.sh <update_file> to unpack the selected firmware update file. The supported file extensions are bin, zip and swu. The result is in the folder unpacked.
4. Modify the options file options.cfg to select the options you need and run patch.sh to patch the firmware files in the unpacked folder. The result is still in the folder unpacked. You may manually modify the current state of the files if needed. You can also prepare different configuration files for different needs based on the default file options.cfg. The custom configuration file is provided as parameter: patch.sh <custom_configuration_file>. If no parameter is provided, the file options.cfg will be used.
5. Run pack.sh to pack the firmware files from the folder unpacked. The result is the file update/update.swu.
6. If your printer is still with the original firmware, you have to make root access first. Then replace the /etc/swupdate_public.pem in the printer with the one from the RESOURCES directory or create your own (make a copy first of the original /etc/swupdate_public.pem key in case you want to return to the original ota updates). Then apply the newly generated custom software update/update.swu by USB update (place the file update.swu in the folder update on the root of a FAT/FAT32 formated USB disk). If your printer already has custom update installed, then you can directly apply the new update by USB update.

Default password for the root access (UART and SSH) is toor but it can be changed in the options.cfg file.

OPKG will be included with the option ssh if it is enabled.
