Add printer in LAN mode by IP address #702
Comments

Multicast being blocked between wired and wireless connections is fairly common even on consumer/SOHO devices, so this would be nice even just for better connectivity. |

From Wikipedia [SSDP] was formally described in an IETF Internet Draft by Microsoft and Hewlett-Packard in 1999. Although the IETF proposal has since expired (April, 2000),[1] SSDP was incorporated into the UPnP protocol stack, and a description of the final implementation is included in UPnP standards documents Doesn't seem very sane to use with anything, tbh. |
|
Even fallback to regular DNS would be an improvement - I can always setup a local DNS entry for the printer.. |
|
Which reminds me that IPv6 support would be nice. Seems the printer is running Linux after all, so it really can't be that hard. |
That explains why i cant get the Printer working in lan mode in my vlan network… i should have used wireshark in the first Place… pls bambu: add „printer by ip“ support |
You can remedy that by enabling multicast routing or forwarding between VLANs if the router understands that sort of stuff. Still, adding by IP or DNS name shouldn't be very hard to fix and is the good solution to this. |
|
As a temporary solution. I've written a script to generate an unsolicited response to the upnp/ssdp discover, to tell BambuStudio the IP of the printer. It's meant to be run on Linux, but may work on Windows too if run in a VM/Container/Cygwin. It has to be run each time BambuStudio is restarted, as Bambu will forget until it receives the response to its M-SEARCH ssdp:discover. |
|
Better fix this in source. Such workarounds just make Bambu relax since "there's a workaround". The Bambu printers aren't cheap and this should be easy to fix. |
|
Lots of fixes and improvements with v1.4 but this one is still missing. |
|
Can it really be that hard? |
|
With today's outage, this is now especially pertinent. There is already an existing dialogue for this feature as of 1.4.2 -- there should be very few blockers for this now. |
|
My thoughts on this. When the printer connects to the network it should display its ip address and passcode for bambu studio to connect to it. I am not a network expert so I am not sure about broadcasting its availability on the network. I think this should be okay on a LAN, which makes it discoverable without having to type in the IP address in bambu studio. |
|
+1 i should be able to use static ip addresses and point bambu studio to that. this issue is preventing me from using the printer in lan mode with a vpn |
|
With the latest issue happening now: https://www.reddit.com/r/BambuLab/comments/15rznpy/printer_started_printing_by_itself_damaged_itself/ This issue should really receive priority asap! |
|
I posted this in another issue but it looks like this is the primary issue for adding printers by IP address so I'm going to post it here too, sorry about the spam. I can delete the comment in the other issue if it's a problem :) I got a little bit frustrated with this issue because having command and control in the slicer is a key feature IMO. So I reimplemented the networking plugin to add this feature (and others). |
|
Another +1 for this feature. |
I've converted the SSDP script to PowerShell, so that it can be used on Windows as well. |
I just tested it and it's ok, it works, thanks! I will only add that it may be necessary to change the port, in my case it is listening on port 1990 instead of 2021 (here is information about these ports: https://wiki.bambulab.com/en/general/printer-network-ports). The $TARGET_IP line itself is not needed in the powershell script because it is not used at all in this case. |
|
It is quite crazy you cannot add a printer by IP - it means a lot of user simply cannot connect to it and means you can return the printer and get a refund, since it does not work. |
|
I imagine it's hard to find time to figure out the user experience, but if anyone from Bambu is reading this, I think I'd like to suggest that you add a way to configure printers by static IP in the config file, and worry about the slicer UI code for that configuration later when you have more time available. A lot of users would be okay editing a config file if it means not having to return the printer (or in my case, re-implement the entire networking plugin in Rust). To anyone here who runs linux and likes fiddling around with semi-broken software, the bambu-farm repo I linked earlier will get you up and running. It's not perfect. Immediately after a print it drops into an infinite loop on a worker thread so you have to close the slicer and restart the server-side program too, but it gets the job done for me and might be useful for someone else at their wit's end. |
|
Yeah, without this, the X1E that my employer bought doesn't work on our corporate network. I can ping the printer and it's on the same subnet as my computer, but because it's trying to auto-discover, I can't add it to Bambu Studio. |
Corporate environments are an especially pertinent example -- mDNS is oftentimes disabled as a basic security measure. |
That's exactly what's causing the issues I'm running into. And for Bambu to sell the printer specifically on the merits of compatibility with a corporate environment, but not support this direct IP / hostname specification seems disingenuous at best. |
|
We are considering this feature, and recently it's the Chinese New Year holiday, so our responses might be slower. We apologize for any inconvenience caused. |
|
Happy new Chinese year! But I wonder - it's been more than 14 months since I posted this. Does it really take that long to fix such a minor thing? |
|
I also require LAN mode because the printer is located in a separate VLAN to enhance data security. Currently, I am unable to access the printer via Bambu Studio, as it cannot be discovered through mDNS accross VLANs. |
|
It's not even mDNS, it's SSDP, which started out as a crude draft and then later became part of uPnP. But - since SSDP is based on UDP, you can spoof it |
|
However, does this mean I have to spoof it every time I start Studio? Additionally, I would like to use Bambu Handy via VPN in LAN mode. Is there a workaround for this as well? |
|
The slicer (Bambu Studio or OrcaSlicer) will cache the address, so don't worry. As for BambuHandy, ask Bambu about it - I guess they'll just say that you'll need internet access. |
|
Btw, Bambu knowingly breaks AGPL with the bambu drivers https://blogg.karlsbakk.net/2024/05/24/more-on-bambus-license-issues/ |
|
If it helps I'm running my X1C in a different VLAN than my desktop machine, I use pfSense as my router/firewall and I installed the Avahi plugin on pfSense with the option to repeat packets across subnets. With the appropriate ports opened between the subnets Bambu Studio works just fine. |
|
It's better to spoof it, so that you don't need to open up unnecessary ports. Also, Bambu really should fix this, along with allowing offline firmware updates. |
|
|
Yeah, offline firmware is available as of recently: https://wiki.bambulab.com/en/x1/manual/X1E-firmware-update-from-SD-card You need to be on v01.01.02.00 which mean an online firmware upgrade first, but at least it's possible now. |
|
That doesn't help all of us that don't have an X1E. I have an X1C, which is basically the same machine as the X1E and this functionaliry has been, and still is, used for all sorts of devices |
|
A collaborator mentioned in #2232 that this will be added in the next update. I hope that actually happens, and am looking forward to it if it does. |
Have you tried it? The title of the video embedded in the how to page is "Offline Firmware Update using SD Card - X1/X1C/X1E" |
Can confirm this works perfectly for remotely accessing my (LAN only) BambuLab A1 (with a few minor modifications like SN/Model) over my Wireguard VPN (Tailscale). Thank you for sharing!!! |
|
Sorry for multiple messages however, are there any updates regarding this? @walterwongbbl @MackBambu |
|
@tdgunes It has been flagged for the 1.10 release. |
Thanks, however it is not clear to me if this feature will be for X1E only, or for all BambuLab printers. Do you have any further information @kluppy? |
|
@tdgunes the people who posted these issues are using X1C/P1S printers so it should apply to at least those and also the X1E. |
I see, however I would like this feature to be implemented for A1 series, as the LAN mode does not work effectively with those as well. |
|
Ia this available on P1S? Because I want to buy it only if it has this implemented already. |
|
@psychedelicu 1.10 has not been released yet, so no. |
But they announce that this will pe included? |
|
The public beta of 1.10 is available and includes binding by IP address! |
|
I'm just getting around to testing out the beta and I can't seem to get my printer to connect via IP address. I have a Bambulab A1.
I've confirmed my access code and IP address are correct and I'm able to connect on LAN as one normally would. Not sure if this is a bug or what is going on here, but it would be interesting to know if anyone else is facing this issue. Correct me if I'm wrong but the printer shouldn't need a firmware update for this to work right? I am under the impression that this feature is all implemented within Bambu Studio. |
|
I also tried and found the same error than you. |
This should not require a firmware update on the printer. We can already get the slicer to talk with the printer by spoofing the SSDP requests so it definitely should not need any update on the printer side. If they make it require a firmware update I'd wonder what else they changed. |
|
It appears this feature in 1.10.0 is also broken or doesn't support my X1E. I am still able to use my wireshark spoofed response on the new version though. |
|
We have bought two X1E at work and I get the same error when testing the feature in the beta release. Using a spoofed message it works. |
|
Actually BabuStudio crashes when I try to connect to the printer. I have a P1S... |
|
I was very happy to see this feature added, but no dice for me either. Though I get a slightly different error, "Failed to publish login request". (Occasionally Bambu Studio also decides to crash instead.) 2 steps forward, 1 step back... Oddly this is described as a failure to connect to Bambu cloud, which is of course nonsense when connecting in LAN mode. P1S, works fine once the printer is discovered via (spoofed or real) SSDP, so definitely no networking issues here.
Filed issue 5070. |
and others
Since the WAN mode is utterly insecure, adding a printer by its IP address would be nice in LAN mode when mDNS isn't available. Either because the printer is on a different subnet and the router doesn't route multicast, which is quite normal or if you have an enterprise wifi system (for instance from Cisco), which also may drop mDNS.
