# Uses the Bambu Studio version of the library and sets some headers like Bambu Studio does. These instructions assume BambuStudio non-flatpak. But you really just need the right version of libbambu_networking.so and libBambuSource.so. Your also need a patched copy of OrcaSlicer.
#
# This is a proof of concept. Just slicing and printing has been tested. It is known to break on reopen of Orca Slicer. You have to logout and login again. Viewing the camera also didn't seem to work.
#
# 1. Install Bambu Studio, https://github.com/bambulab/BambuStudio/releases/tag/v02.06.00.51
# 2. Start Bambu Studio
# 3. Let the normal plugin install
# 4. Make sure your printer is not in Developer mode and not in LAN mode.
# 5. Set up your printer in Bambu Studio.
# 6. git clone https://github.com/OrcaSlicer/OrcaSlicer.git
# 7. cd OrcaSlicer
# 8. cat /path/OrcaSlicer-cloud.patch | patch -p1  OrcaSlicer-cloud.patch is this file.
# 9. ./build_flatpak.sh -i -j X  Where is is how many cores you want to use for the compile, and takes a while. Wise to cut the number of cores to half to prevent running out of memory.
# 10. flatpak install --user OrcaSlicer-Linux-flatpak_V2.4.0-dev_x86_64.flatpak
# 11. flatpak run com.orcaslicer.OrcaSlicer
# 12. Let the normal plugin install
# 13. Close OrcaSlicer
# 14. mkdir ~/.var/app/com.orcaslicer.OrcaSlicer/config/OrcaSlicer/plugins/backup
# 15. mv ~/.var/app/com.orcaslicer.OrcaSlicer/config/OrcaSlicer/plugins/libbambu_networking_02.03.00.62.so ~/.var/app/com.orcaslicer.OrcaSlicer/config/OrcaSlicer/plugins/backup
# 16. cp -a ~/.config/BambuStudio/plugins/libbambu_networking.so ~/.var/app/com.orcaslicer.OrcaSlicer/config/OrcaSlicer/plugins/libbambu_networking_02.06.00.50.so  <-- This filename has to match the version of the library. Normally the filename is libbambu_networking_02.03.00.62.so.
# 17. cp -a ~/.config/BambuStudio/plugins/libBambuSource.so ~/.var/app/com.orcaslicer.OrcaSlicer/config/OrcaSlicer/plugins
# 18. Open OrcaSlicer, if any error/dialog about the plugin, double check the instructions above
# 19. Login to your Bambu account in OrcaSlicer
# 20. Go to the Device tab, confirm your printer appears, is connected, and functioning properly
# 21. Slice and print a model. It will go through the cloud.
