Following on from the conversation in the other thread I thought it might be worth a separate how-to on how to stop Bambu printers from updating to the latest firmware. I'll kick off by explaining what I've done with mine so far, and would welcome any additions and suggestions. I'm no network engineer, know just enough to be dangerous but I think I may have got part of the way there.
My layout:
I dug out an old router ( a TP-Link WD-W9970) and set it up as a bridge, gave it an IP address of 192.168.1.65. The reason for this is that the BT Router has very limited settings and no way I could see of restricting access to the internet while allowing LAN traffic. These two routers are connected with a Cat 5 cable, connected to LAN 1 of the TP-Link (not the LAN/WAN port 4).
From the TP-Link admin page I turned off DHCP, and reserved the address 192.168.1.103 for the X1C 3d printer - this is an address I had seen it use previously. As far as I can tell, the X1C will request any IP address, but by limiting it to just one address makes it easy to set up any other restrictions or filtering if necessary - I thought I might have to but this is where advice from other cleverer folks might come in useful.
Running a couple of diagnostic tests gives this:
and this:
Both these show that the TP-Link has no internet connection, which is what I was after.
I have set the X1C to LAN-only mode - this means I can't use the Bambu Handy app apparently but as I never have and don't feel the need to that doesn't bother me. I can send a print job using Bambu Studio from my laptop (connected to the BT network) to the X1C, and I can monitor it with the camera, select the right filament in the AMS, but I no longer get the 'finished successfully' message on my phone (which also doesn't bother me and is more evidence that the printer can't talk to the internet).
The downside - every now and again the Bambu Studio app loses sight of the X1C, but it always connects straight away when I tell it to. Previously, without the bridge router, it always stayed connected. A minor inconvenience which I don't know how to solve or if there even is a remedy.
I have one particular reservation on whether this is successful or not - by turning off DHCP but then reserving the IP address for the X1C as 192.168.1.103, does that allow the X1C to ask the BT router for a sneaky way out to the internet? Or should I also use some sort of filter or (firewall??) restriction on the TP-Link to make sure this doesn't happen? Bear in mind that the BT router doesn't allow me to do very much at all apart from setting up Parental Controls which will limit everyone on the network.
