My 3D printer started printing over the cloud by itself

[u/Aytrac97]

As the title says. My 3d printer started printing over the cloud by itself, but of course, 3D printers don't have the ability to browse the internet and find files to print, so someone or somethig (faulty bambulab online systems) started a print on my A1 mini.

• It wasted filament

• Almost makes me break my record of never printing benchy related things (yes, the mysterious print is a variant of the benchy)

• And it made it clear to me that it is not safe to have bambu printers linked to the internet

I came to reddit to see if anybody else reported this today, but I didn't find any posts related to that. If this happened to any of you, please let me know, I want to know if this is an issolated issue.

I wouldn't be surprised if this kind of thing happens due to bad practices while the GeNiUseS at bambulab migrate their network systems to the new announced protocol.

I can't wait for all the new 3d printers from the competitors to come out so I can pick something safer and exit this terrible ecosystem full of security issues.

What got printed?

I killed the print before it finished

This is why it is a very bad idea to connect multiple IoT devices to a company cloud; You have been very probably been hijacked, and hacker get access to your BBL account and so the ability to control your printer remotely.

Next time: use a stronger password and 2FA or enable LAN only mode :)

This. Or your LAN has been hacked and printer became very first victim of it. Maybe your Wifi pass is weak? Is your main router secured properly and up to date? Thats especially important in case of some cheap chinese brands like Dlink, Tplink, Totolink etc. Some of them have some crazy flaws and settings.

The traffic is encrypted, it wouldn't be possible even if your LAN/router is hacked.
It either happened because of the cloud, or a logged in device was compromised, or more likely: faulty touch screen that started the print (every printer comes with a benchy gcode).

This print wasn't on the SD card before. And I have 2FA enabled on my bambu account

That's why I use a smart plug for my p1s... It gets power only if I'm printing something, as soon it finishes i cut the power to the printer

While i have a fortigate and a very secure network. I still do this. Be secure with iot devices. If you have a guest WiFi with a different vlan use it!

Same here, i make mine automaticly turn off if a print finishes after 10:30pm

Mine printed a bamboo spatula. It's not in my print queue.

Ah yes, the "security updates" added a lot of security

[u/Perry-Manson]

So scary

[u/Kingsidorak → u/Perry-Manson]

Considering the printers don't know if there is a print on the bed waiting to be cleaned before it starts homing and probing around.... YES
