My concern isn’t the STLs… it’s the fact you basically have a laptop running their software and a fully functional computing device (the printer), both connected to China at all times. Remember, every company in China is basically an extension of the CCP/CPC, and they have the ability and motivation to have those machines doing more than just printing things. That ability can remain dormant until called upon to perform whatever it wants. Basic network monitoring can be done in a totally undetectable manner.
I’ve run the Alibaba app on a burner phone and watched it report back tons of stuff to China including audio streams, captured in a way that really fucks up your audio output (especially to bluetooth speakers), but it does it without tripping the Android microphone notification. Clearly using a hack or vulns in the stack, which is why it makes regular audio output jenky and prone to cutouts etc. I discovered this by accident on my day to day phone which I use all the time with bluetooth speakers. After installing the alibaba app, all audio started borking hard. Uninstalled it and things went back to normal. Now I have an older IoT phone with cams and mics taped over (tested, works great) and that’s where I have all my IoT nonsense etc.
The Bambu printer is firewalled from the internet for now… as is the surface tablet I use to slice and print… I can transfer files via SD card for now. I have VNC on the surface tablet for easy remote control from my desk and file transfers work fine over the local network to the table. I also like the ability to cache and load regularly printed things to the printer itself for each picking and printing regularly used parts from internal memory… though I don’t have anything like that yet that I print a lot of… but maybe in the future.
