It kept nagging me to update, so I did. All my filament and print profiles are gone. When I look at the folder it’s complaining about, there is no fdm_filament_common.json.
I hope there’s a fix.
They are stored in the cloud, try logging out of Studio and back in.
I got excited, but it didn’t work. It doesn’t even have system presets.
“Failed loading C:…/BBL/filament/fdm_filament_common.json
Suggest cleansing the directory C:…BambuStudio\system firstly”
Ah, OK. Shutdown studio and zap that directory. Might have been something locking it like another studio instance, potentially need to re-install. In the installation processing you can watch it, it goes through and deletes all of those files itself, something prevented it this time.
OMG I had a mini heart attack. That worked. THANK YOU!
So if I just back that directory up somewhere locally (just in case) is that all I need to back up?
A couple of days ago I was playing around with the json files (windows version) (short story long on my printing PC I have 1.x Bambu studio connected to P1s with older firmware, printer has never been connected to cloud, never will be and has only been LAN only since day it was birthed from shipping box). I have 2.x BS in a VM and was “updating” filament entries in the 1.x BS and I noticed they had indeed dropped one of the …common… json files (that PC is not available at the moment so can’t check name for sure) and had added 1 and 2 nozzle json files. The fact that it is complaining about not finding a file to me makes it sound like an incomplete or partially failed upgrade? Will be interesting to see what BBL comes back with.
Glad krellboy was able to help you out.
Just FYI (and this is informational purposes only, not a recomendation to start editing files)
I looked and it’s fdm_process_bbl_common.json that was dropped and looks like they now use fdm_process_single_common.json and fdm_process_dual_common.json instead.
Personally I keep copies of the entire BS file structure (windows) under
(your drive here):\Program Files\Bambu Studio
and
(your drive here):\Users(your windows user name here)\AppData\Roaming\BambuStudio
The \Users\ structure is where my BS preferences are stored
@krellboy I would guess that they must be stored in both the cloud and on the local machine since I do online and offline work and I know that all of my custom presets and any newer Bambu ones I add are on my PC. Good catch on the locked file issue. I wouldn’t have thought of it.
Thanks. I’m pretty sure when I installed the update I didn’t know there was another instance of BS open. So it couldn’t do what it needed to do.
