Is anyone else concerned about internet-connected 3D printers? (lemmy.ml)

Howdy, folks!

I'm teetering on the brink of connecting my Sovol3D S06 ACE to my wireless network, but I'm pausing because this device can make physical real-world actions like:

  • record photos and videos using its built-in camera
  • shaking so much that it manages to knock itself on the floor
  • melting so much plastic that it dribbles all over itself and then all over everything around and beneath it
  • consume lots of electricity and cost me a fortune on my utilities bill
  • burn the house down

None of this happens in normal usage, of course, but watching it self-calibrate did make me wonder:

  • how safe the firmware is?
  • is it retrieving instructions from Sovol3D or some other party by itself?
  • is it sending records of my print jobs to a 3rd party?
  • is it sending photos and videos to a 3rd party?
  • how safe the firmware is once its receiving arbitrary network traffic?

All IPv4 traffic from the internet goes through a NAT/firewall that I conceivable control, but my devices all get public-facing IPv6 addresses, and the default SSH password on all of these printers is publicly-documented

It looks like the Sovol3D S06 ACE firmware is https://www.klipper3d.org/ + https://www.obico.io/ + some unknown amount of stuff that Sovol3D adds on top, and it doesn't seem like they've kept the public source code up-to-date: https://github.com/Sovol3d/SV06-ACE

I do already self-host https://www.home-assistant.io/ and plan to integrate the 3D printer with it, avoiding any cloud behaviour as much as possible, but I'm wondering if anyone else has already done this and has any advice on what to avoid?

Cheers! <3

Ask the admins to setup the NAT rule.

But yeah, ultimately it's a pretty poor decision on Prusa's part to make it hardcoded. I didn't even realize my mk4 doesn't allow manually setting the time. I wonder if anyone has brought it up on the firmware repo.

I have DHCP announcing the NTP server, I haven't seen my prusa attempt to talk outside of my network. But I do see a boatload of IoT stuff ignore my local NTP all the time. Very frustrating.

I've opened an issue asking for a manual offline way to set the time, and I saw another one asking for a DHCP option.

I've tried asking the admins, and they were mad I connected the printers to the network to begin with 😅
