SSDP can only be tried on a machine that shares the printers' network segment, and the development container is a router hop away. This builds the existing discover_printers example as a Windows .exe and uploads it as a CI artifact, with a README for whoever runs it and a SHA-256 file. Uses the windows-latest self-hosted runner continuum-cad already uses (Windows PowerShell 5.1, MSVC present, upload-artifact@v3 only). The proxy links OpenSSL directly and Windows has none, so the job builds it with vcpkg (x64-windows-static-md, linked into the .exe) in a directory of its own, away from the CAD pipeline's. The job smoke-runs the exe, then runs the discovery tests on Windows after the upload, so a Windows-only test failure turns the job red without withholding the executable. Not run anywhere yet: this container cannot build for Windows (no MSVC or mingw). The first CI run is the first real build.

discover_printers.exe - finds Continuum-compatible 3D printers on this network
|
|
=============================================================================
|
|
|
|
Run it from PowerShell, in the folder it is in. It only LISTENS and asks
|
|
printers who they are. It sends no passwords or access codes and changes
|
|
nothing on any printer.
|
|
|
|
The test we need (Bambu printers announce themselves over SSDP multicast,
|
|
which only works if this PC is on the SAME network segment as the printers -
|
|
same Wi-Fi/Ethernet, not through a VPN, not a guest network):
|
|
|
|
.\discover_printers.exe raw 120 2>&1 | Tee-Object ssdp.txt
|
|
|
|
That listens for 2 minutes and prints EVERY datagram it hears, then what it
|
|
understood. Send back ssdp.txt. "listening for SSDP ... interfaces=[...]"
|
|
near the top lists the adapters it joined; the one on the printers' network
|
|
should be there.
|
|
|
|
Other commands:
|
|
|
|
.\discover_printers.exe listen 30 SSDP only, Bambu printers
|
|
.\discover_printers.exe sweep 192.168.0.0/24 probe every address on a subnet
|
|
.\discover_printers.exe all 192.168.0.0/24 both, merged
|
|
.\discover_printers.exe identify 192.168.0.21 one known address
|
|
|
|
Windows Firewall will ask whether to allow it on first run. Allow it on
|
|
PRIVATE networks; without that, Windows drops the multicast and the result is
|
|
"No printers found" even when printers are there.
|
|
|
|
Check the file is intact: Get-FileHash .\discover_printers.exe -Algorithm SHA256
|
|
(compare with SHA256.txt)
