Tool to send files to Bambu Connect using LAN mode

Myself and my buddy wanted to learn about this Bambu Connect Beta software that will supposedly be used for third party apps, such as Orca Slicer, to send files to your printer. Chat GPT may have also been involved with this project.

After figuring out the encoding and url generation I threw together this quick and dirty tool to allow anyone to send files from their PC to the Bambu Connect interface. I was hoping this would lead to an easier method to send files but it does not. It is still easier to open Bambu Connect, search for your printer, enter the access code, and drag and drop files on the window. At least Bambu Connect does allow for sending files in LAN mode without having to re-slice them every time.

What we found is there is no encryption or security features when using LAN mode. A properly formatted url is all that is needed. I have no way to test if there is when not using LAN mode but I’m sure it likely is implemented… I hope. There is a tool in this list that can be used to test.

At this time you can only send “.gcode.3mf” files as I’m not sure if any other file types can be used. Be aware that I don’t have much programming experience so there may be bugs in the tool.

Download, Send to Bambu Connect LAN mode.exe

If you are an AutoHotKey user, (v1), you can download the script.
Send to Bambu Connect LAN mode.ahk

Or if you would simply like a webpage that possibly works in all modes,
BumbuConnect.html

All you need to do is choose a file, change the name if desired, generate the url, and send the file to Bambu Connect. If for some reason the url did not get properly formatted, Bambu Connect will not load the file.

As I said, this does not make sending a file any easier. The link will open Bambu Connect, but you still have to click to make BC accept the file, search for your printer, enter the access code, make sure the correct printer is chosen, even if there is only one, and then click Send. If you leave BC open indefinitely you can skip a few steps, but not all.

I was hoping that using the url would somehow, magically, allow a quick and clear transfer of the file from your PC to your printer, but just by looking at the url I didn’t think that was really possible. Instead it adds way too many steps into the process.

Give it a try if you like. Send feedback if you wish. But remember it could have some bugs, such as window and/or font scaling, and since it doesn’t look to be very useful, it likely won’t be updated much.

Be sure to scan for viruses before running, scan ALL downloaded software for viruses before running. I don’t know how to write a virus but that doesn’t mean I didn’t let my PC get infected with something that could attach itself. So scan for viruses and use at your own risk.
