Two recurring virtual-printer support pains, both on the Virtual Printers
settings page.
Setup check: a stethoscope action on each VP card runs a pass/fail/warn/skip
checklist — VP enabled, services running, bind interface still exists, access
code set, target printer (proxy mode), and a live TCP probe of the FTP / MQTT
/ discovery ports on the bind IP. start_server swallows per-service bind
errors, so a service object can exist while nothing is listening; probing the
bind IP from outside is the only reliable signal and it catches the common
"VP not visible in the slicer" bind-IP-conflict and stale-interface cases.
Slicer certificate: virtual printers present a TLS cert signed by a shared CA
the slicer must trust. Until now users had to docker exec in and cat
bbl_ca.crt. A "Slicer certificate" row on the settings card now offers Copy
and Download (bambuddy-virtual-printer-ca.crt) plus the SHA-256 fingerprint.
GET /virtual-printers/ca-certificate returns only the public certificate; the
CA private key never leaves the backend. The CA is generated on demand so the
button works before the first VP is enabled.
Backend:
- services/virtual_printer/diagnostic.py — run_vp_diagnostic + port probes
- schemas/virtual_printer.py — VPDiagnosticResult
- CertificateService.get_ca_certificate_info() + manager helper
- routes: GET /virtual-printers/ca-certificate, /{vp_id}/diagnostic
Frontend:
- VirtualPrinterDiagnosticModal.tsx; stethoscope button on VirtualPrinterCard
- caCert row on VirtualPrinterList; utils/clipboard.ts (shared copy w/
non-secure-context fallback + downloadTextFile), de-duplicating the
existing FQDN-copy logic
- vpDiagnostic.* + virtualPrinter.caCert.* across all 9 locales
9 backend unit tests + 4 route integration tests + 6 frontend tests.
Backend ruff clean, frontend build clean, i18n parity green.
