README/certs/README/.env.example/printers.example.toml were all still
describing this as a learning-stage stub with no real printer protocol
clients - rewritten to reflect the real Bambu MQTT client, cert
auto-pinning, and marlin serial connection that now exist.
- Remove examples/fetch_bambu_cert.rs: its manual fetch-and-save workflow
is now what BambuPrinter::connect()'s ensure_trusted does automatically
on every connect, so it has no remaining use case.
- Fix examples/printer_polymorphism.rs, which no longer compiled -
dispatch_gcode was replaced by real methods earlier this session;
swapped in print_status() as the vendor-only-extension example.
- Remove Config::bambu_ca_cert_overrides/bambu_require_valid_cert and the
.env vars documenting them - confirmed dead (nothing read them),
fully superseded by printers.toml's per-printer ca_cert_path/
require_valid_cert plus automatic trust-on-first-connect pinning.
- Fix stale doc comments in printer/mod.rs and printer/bambu.rs that
described certificate trust and MQTT as not built yet, or referencing
the now-removed example.
No behavior change in the daemon itself - verified with cargo build
--examples and a live run of printer_polymorphism and auto_connect_bambu
against the real P1P/H2C printers.
Checked BambuStudio's resources/cert/ directly: it ships exactly one
LAN-mode CA (the bundled bambu_ca2.pem) plus an unrelated cloud-API leaf
cert — no second file to bundle for P1P. So a P1P's certificate is a
genuine per-device case, same as older units' 'download it from the
printer' flow, and a single Config-wide override path can't express 'most
printers use the bundled CA, but this one doesn't'.
Config.bambu_ca_cert_path (Option<PathBuf>) -> bambu_ca_cert_overrides
(HashMap<printer_id, PathBuf>), parsed from a comma-separated
CONTINUUM_BAMBU_CA_CERT_OVERRIDES env var. BambuTls::from_config renamed
to ::resolve to make clear it's called once per printer with that
printer's own override, not once for the whole config.
Verified with cargo check --all-targets and a full run of
cargo run --example printer_polymorphism.
Removed adapters/ (rumqttc MQTT, suppaftp FTPS, reqwest HTTP), plate_changer/
(tokio-serial), discovery/, and cache.rs (rusqlite) — src/printer/ already
covers 'talk to a printer' as simple stubs, so keeping a second, more complex
version alongside it was redundant. main.rs goes from 6 concurrent tasks to
2 (uplink + go2rtc). uplink/ drops channels, jitter, and Send-bound futures.
Verified with cargo build + cargo run --example printer_polymorphism.
