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.
The "Report a Bug" panel scans every configured printer on open and shows
connection problems inline. The first cut rendered a full ~6-row checklist
per problem printer, stacked — on a large fleet that pushed the description
box and Submit button below the fold in the max-w-md / max-h-80vh panel.
The diagnostic section is now a compact summary: one "N of M printers have
connection issues" line plus the affected printers as collapsed rows
(healthy printers count toward M, render no detail). Each row expands on
demand to that printer's full checklist via the shared Collapsible widget;
a single problem auto-expands since that's the case where inline detail is
wanted without a click. Panel height is now fixed regardless of fleet size.
- BugReportBubble.tsx: diagnostic query pairs each result with the printer
name (new DiagnosticEntry type); render block uses Collapsible rows
- i18n: new bugReport.diagnosticSummary ({{problems}}/{{total}}) replaces
static diagnosticHeading; diagnosticIntro reworded count-neutral — all 9
locales
- 2 new BugReportBubble tests (collapsed-then-expand; single auto-expand)
Five follow-up fixes to cross-printer re-slicing, all surfaced while
testing archive re-slices.
1. Re-sliced archive now records the printer it was sliced FOR.
slice_and_persist_as_archive copied sliced_for_model from the source
archive, so re-slicing X1C->H2D still showed "X1C sliced". Read it
from the freshly-sliced 3MF's parsed metadata instead, falling back
to the source only when absent.
2. Real slicer rejections are surfaced instead of silently masked.
_run_slicer_with_fallback retried with the 3MF's embedded settings on
any sidecar 5xx — including genuine content rejections (object off
the bed, incompatible filament temps), which "succeeded" only by
re-slicing for the source's original printer. A new
_slicer_rejection_message detects the slicer's own error string and
surfaces it as a 400; the embedded-settings fallback is kept only for
true CLI crashes.
3. A failed slice opens an error modal, not a 3s toast. The slicer's
reason is actionable and a toast hides it before it can be read. New
AlertModal (acknowledge-only); SliceJobTrackerContext shows it on a
failed job. New slice.failedTitle key in all 9 locales.
4. Sliced files no longer report "0 g" filament usage. The sidecar
doesn't always populate the X-Filament-Used-* headers;
ThreeMFParser._parse_gcode_header now also reads the slicer's own
"total filament weight/length" from the G-code header, and both
slice-persist paths fall back to it when the sidecar reports 0.
5. Nozzle-class re-slice guard. Re-slicing across the single-nozzle <->
dual-nozzle boundary (e.g. X1C -> H2D) fails BambuStudio's
multi-extruder validation; both slice routes now reject it up front
with a clear 400. The dual-nozzle model classification — previously
an inline tuple duplicated across start_print and the K-profile
routes — is centralized into DUAL_NOZZLE_MODELS / is_dual_nozzle_model
in printer_models.py, consumed by all three sites and the guard.
Full cross-nozzle-class re-slicing (dual-nozzle project_settings
reconciliation) remains separately tracked.
Tests: _slicer_rejection_message, _canonical_printer_model,
guard_nozzle_class_reslice, is_dual_nozzle_model, the G-code-header
filament parse, AlertModal, and end-to-end slice-API coverage including
an X1C-archive-to-H2D 400. Backend ruff + i18n parity clean; frontend
build clean.
The browser console logged "downloadable font: rejected by sanitizer"
for inter-latin.woff2 on every load. The #1460 PWA fix added @font-face
rules pointing at /fonts/inter-latin.woff2 and bundled the woff2 files
into static/fonts/, but main.py only mounts /assets, /img and /icons as
static directories. With no /fonts mount, /fonts/*.woff2 fell through to
the SPA catch-all and returned index.html with 200 OK; the browser's
OpenType sanitizer rejected the HTML-as-a-font.
Add a /fonts StaticFiles mount alongside /img and /icons. The woff2
files themselves are valid (verified — Inter variable, latin and
latin-ext subsets).
Also bump the service worker STATIC_CACHE version (v26 -> v27). sw.js
lists the two font URLs in STATIC_ASSETS, and cache.addAll() treats the
200 OK HTML as a successful fetch — so it had cached index.html under
the font URLs and served it cache-first. The version bump makes the
activate handler purge the poisoned cache and re-fetch the real fonts.
File Manager cards, search and sort keyed off file_metadata.print_name,
which ThreeMFParser lifts from the 3MF's <metadata name="Title">. That
title is the in-app project title — generic "Exported 3D Model" for any
Bambu Studio "Save As", a marketing title for a MakerWorld download —
and almost never the filename the user saved as. A card for
Whatever.3mf showed "Exported 3D Model"; correcting it needed a rename
round-trip, since the Rename dialog disables Save while the name is
unchanged.
The slicer-output write path already dropped print_name for this exact
reason; the four other paths that store parsed 3MF metadata onto a
LibraryFile did not — external-folder scan, managed multipart upload,
the multi-file ZIP-upload branch, and MakerWorld import.
Add a shared _without_print_name() helper and apply it at all four
import paths; switch the slicer path to it so there is one rule. A
LibraryFile's display name is its filename — only PrintArchive carries
a real print_name, which is untouched. Remove the now-redundant
filename->print_name mirroring in the rename route.
Add a one-time idempotent data migration (_migrate_drop_library_print_name,
SQLite json_remove / PostgreSQL jsonb key-removal branched on
is_sqlite()) so libraries imported before the fix correct themselves
without the rename workaround. No frontend change: print_name || filename
yields the filename once print_name is gone.
Tests: 6 new in test_library_print_name.py cover _without_print_name and
the migration (incl. idempotency, siblings preserved, null metadata).
SQLite migration branch verified by test; PostgreSQL branch verified
against a real Postgres instance.
A P2S support bundle on 0.2.5b1 — per-model probesize fix already
applied — showed the camera still failing: ffmpeg connects, stays alive
30+ seconds, emits zero JPEG bytes, the 30s stdout.read times out,
reconnect loop repeats. No ffmpeg stderr appeared anywhere in the log to
explain why.
The cause was a diagnostic bug, not the camera path. _read_ffmpeg_stderr
called process.stderr.read() — read-to-EOF. A stalled-but-still-alive
ffmpeg (the P2S RTSP failure mode) never closes stderr, so the read
blocked until the 2s wait_for timeout and returned None, discarding the
banner + stream-analysis lines ffmpeg had already printed. ffmpeg stderr
was captured only when it fully exited; once the probesize bump turned
the earlier crash into a hang, the diagnostic went dark.
Drain stderr incrementally in bounded 8KB chunks (64KB cap), returning
whatever ffmpeg printed so far whether or not it has exited. Also log
the resolved per-model probesize/analyzeduration on the info-level
"Starting RTSP camera stream" line, and log the full ffmpeg argv at
debug level with only the credential-bearing camera URL redacted
instead of hiding the entire command.
No behaviour change to streaming — this makes the unresolved P2S RTSP
stall diagnosable in the next support bundle.
The #1395 camera-diagnostic follow-up (stethoscope control-bar icon,
Diagnose button in the stream-error state, CameraDiagnoseModal) shipped
wired into EmbeddedCameraViewer.tsx only — the embedded camera mode.
CameraPage.tsx, the standalone window opened at /camera/{id} when
camera_view_mode is "window" (the default), never got it.
A reporter on window mode could not see the stethoscope regardless of
container rebuilds or cache clears: the camera.diagnose strings are in
the bundle but come from EmbeddedCameraViewer, which never renders in
window mode. Switching to overlay mode surfaced it instantly.
Port the diagnostic into CameraPage.tsx: Stethoscope control-bar button
between Refresh and Fullscreen, a Diagnose button next to Retry in the
streamError block, and the CameraDiagnoseModal render. No new i18n keys
— camera.diagnose.* already exist in all 9 locales. The backend
per-model camera-profile fix from the same issue is view-mode-agnostic
and unaffected.
Several "container hangs after adding a printer" reports (#1486) share a
signature with nothing to act on: HTTP goes silent, /health hangs, the
process may ignore SIGTERM, and the log just stops mid-stream - a frozen
asyncio loop cannot log a thing.
loop_watchdog re-arms faulthandler.dump_traceback_later() from an async
heartbeat. While the loop ticks the timer is cancelled and re-armed before
it can fire; if the loop stalls for 30s the heartbeat can't re-arm and
faulthandler's C-level timer thread dumps every thread's stack to stderr,
so the blocked frame shows up in `docker compose logs`.
A restart during an active print duplicated the running job in the
archive, and every further restart spawned another. on_print_start
re-attaches by subtask_id, falling back to a name match plus a 4-hour
staleness cutoff that cancelled + recreated any name-matched 'printing'
archive older than 4h - destroying the live archive of every long print.
Two fixes:
- start_print records the minted subtask_id (last_dispatch_subtask_id);
on_print_start falls back to it when the printer hasn't echoed one
yet, so queue/scheduled archives persist a restart-stable id.
- Replace the 4h cutoff with a progress-aware check: a name-matched
'printing' archive resumes whenever the printer reports real (or
unknown) progress; it is stale only when the printer shows a
freshly-started print (<1%) on an archive over 2h old.
The Color Catalog sync built its httpx.AsyncClient with no User-Agent, so
it leaked httpx's default python-httpx/x.y string - the only outbound
client that did; bambu_cloud, makerworld and firmware_check all send
Bambuddy/1.0 (+https://github.com/maziggy/bambuddy). It now sends the
same honest UA.
Found while investigating an issue - a Cloudflare 403 on the sync that
turned out to be the reporter's network/IP reputation, not Bambuddy. The
UA leak was a separate inconsistency found in passing; this change does
not by itself resolve a Cloudflare IP block.
FileManagerModal ran its file-listing query with refetchInterval 30000,
opening a fresh FTPS connection (full TLS handshake) to the printer every
30s while the modal was open. On fragile controllers like the P1S that
load tipped MQTT, FTP and the camera into simultaneous timeouts. Drop the
interval; the listing still refreshes on open, directory change, after
upload/delete, and via the manual Refresh button.
Also log STL thumbnail failures with a traceback (exc_info) so a
data-specific "str / str" TypeError can be located from a support bundle.
The process dropdown still mixed @BBL P2S presets into an X1C list:
slicerPrinterMatch matched cloud/standard presets by parsing the
@BBL <model> name suffix against a hardcoded model-code allow-list
that was missing P2S, H2C and X2D — so those presets resolved to
"unknown" and stayed in the main list instead of "Other printers".
Drop both hardcoded model tables. Compatibility now comes from the
user's uploaded Slicer Bundles: a bundle is scoped to one printer and
lists the presets it ships, so a preset matches a printer exactly when
some bundle for that printer contains it. New models are covered the
moment their bundle is uploaded.
Bambuddy installed as a PWA on desktop but not on Android. Two causes:
- Chrome for Android removed the automatic install banner in Chrome 108.
With no beforeinstallprompt handler, Android had no install path. New
InstallAppButton captures the event and re-fires it from the sidebar.
- index.css pulled Inter from fonts.googleapis.com: breaks offline, trips
CSP, and the service worker answered the failed cross-origin request
with cached index.html. Inter is now self-hosted; the SW skips all
cross-origin requests and caches the font; CSP drops the Google hosts.
The H2S never ran flow-dynamics calibration even with the print option
enabled, because start_print built the project_file command wrong:
- extrude_cali_flag was hardcoded to 0. A BambuStudio request-topic
capture from a real H2D (plus X1C/P2S captures) shows it is always 1
(run calibration) or 2 (skip, reuse stored PA), paired with flow_cali,
never 0 — so the printer skipped calibration regardless of the toggle.
- flow_cali and the other calibration/leveling fields were integer-
encoded for the H2 family on a mistaken belief that H2 firmware
requires 0/1. The same capture sends plain JSON booleans for every
model; the belief conflated these fields with use_ams (which does
need to stay boolean — the actual #1386 cause).
Fix: extrude_cali_flag = 1 if flow_cali else 2; send timelapse,
bed_leveling, flow_cali, vibration_cali and layer_inspect as booleans
for all models; drop the is_h_family integer-conversion branch.
use_ams is unchanged.
Corrected the two tests that asserted the integer format and renamed
them; all three model tests now also assert extrude_cali_flag.
With "Group similar" enabled, the collapsed group row showed a single
member's values — a group of five 1 kg spools displayed 1000 g instead
of 5 kg (#1368).
The group header now aggregates across all members: the table view's
Label / Net / Gross / Used / Remaining columns and the grid card's
weight figure show group totals. Identity columns (Material, Brand,
Colour) and the Cost/kg rate stay per-spool-correct since they are the
group key; per-spool-only fields with no meaningful total (dates,
location, note, tag ID) keep the representative member's value. The
expanded per-spool rows are unchanged.
New aggregateGroupSpool helper with 4 unit tests; the table group
component's header prop is renamed representative -> headerSpool.
Frontend-only — all data was already in the spool list.
The Slice dialog listed every process / filament preset regardless of
the chosen printer, and always defaulted to the first listed preset
rather than what the 3MF was prepared with (#1325).
Matching uses the slicer's own compatible_printers list for imported
(local) presets and falls back to the "@BBL <model>" name suffix for
cloud / standard presets. Compatibility-unknown presets are never
hidden.
Defaults: the printer and process dropdowns default to the preset
names embedded in the source 3MF's project_settings.config when those
presets are available; the per-slot filament and process pre-picks
prefer a printer-compatible preset, and switching the printer re-picks
any selection left incompatible.
- UnifiedPreset gains compatible_printers, exposed for the local tier
- plates endpoints return embedded_printer / embedded_process
- new frontend util slicerPrinterMatch.ts; extract_embedded_presets_from_3mf
- slice.otherPrinters added across all 9 locales
The Slice dialog listed every process / filament preset regardless of
the chosen printer (#1325). Picking a printer profile now filters both
dropdowns to compatible presets; presets resolving to a different Bambu
model move into a trailing "Other printers" group.
Matching uses the slicer's own compatible_printers list for imported
(local) presets, and falls back to the "@BBL <model>" name suffix for
cloud / standard presets where no compatibility metadata is available,
so all three tiers are covered. Compatibility-unknown presets (custom
or untagged) are never hidden. The pre-pick and printer-switch paths
follow the same rule.
- UnifiedPreset gains compatible_printers, exposed for the local tier
- new frontend util slicerPrinterMatch.ts with the matching logic
- slice.otherPrinters added across all 9 locales
Full European Spanish translation — frontend/src/i18n/locales/es.ts
covers all 4899 keys with placeholders, plural forms, and inline
markup preserved. Registered in i18n/index.ts (resources,
supportedLngs, availableLanguages) and selectable as "Español".
check-i18n-parity.mjs auto-discovers the new file; added an
ES_COGNATES allow-list for genuine Spanish cognates and brand/format
tokens so Check 4 does not flag them as untranslated leaks. Brings the
supported-language count to 9.
A triage review of the last 200 closed issues found ~1/3 were
user-side setup errors — printer not in LAN developer mode, blocked
ports, Docker bridge networking, wrong access code, cross-subnet —
each costing a multi-round-trip support exchange.
Add a Connection Diagnostic that runs those checks automatically:
- backend/app/services/printer_diagnostic.py: TCP probes of MQTT
8883 / FTPS 990 / RTSPS 322, LAN developer mode, Docker network
mode, printer/host subnet match, MQTT credential class; each
check returns pass/fail/warn/skip with a localized fix.
- Routes: GET /printers/{id}/diagnostic (saved printer) and
POST /printers/diagnostic (pre-save Add-Printer flow).
- ConnectionDiagnostic.tsx: modal + shared checklist, surfaced from
the printer card actions menu, an offline-printer quick button,
the Add-Printer dialog, and a new System-page section.
- The in-app bug reporter scans configured printers when the form
opens and always shows the result inline — a healthy confirmation,
or the detected problem and its fix.
- config.yml troubleshooting link repointed to the rendered wiki
page; bug_report.yml gains a diagnostic checkbox.
Diagnostic strings translated across all 8 locales. Backend service
unit tests (15) + frontend modal tests (3). Ruff clean, frontend
build clean, i18n parity green.
GET /spoolman/spools/unlinked hid any spool with a non-empty
extra.tag from the AMS-slot assignment picker. extra.tag is only an
RFID/NFC matching key -- OpenSpoolman writes its own NFC tag value
into that same Spoolman field -- so every OpenSpoolman-tagged spool
became un-assignable in Bambuddy even when it occupied no slot.
get_unlinked_spools now determines assignability from the
spoolman_slot_assignments table (the documented source of truth for
slot assignments) and ignores extra.tag entirely. Both link_spool and
the AMS auto-sync upsert a row there for every occupied slot, so the
ledger is complete. get_linked_spools and find_spool_by_tag still use
extra.tag -- they are genuine tag-match maps and are unaffected.
Internal-inventory mode needs no parallel change: it stores tags in
its own DB with no Spoolman extra collision.
Updates test_get_unlinked_spools_success and adds
test_get_unlinked_spools_excludes_slot_assigned.
notify_missing_spool_assignments_on_print_start queried only the legacy
SpoolAssignment table. In Spoolman mode that table is empty -- bindings
live in spoolman_slot_assignments -- so every used tray was flagged
missing, firing a false-positive notification on every print.
- spool_assignment_notifications.py: the assigned-tray set is now the
union of SpoolAssignment + SpoolmanSlotAssignment rows. Union-only,
so legacy-mode behavior cannot regress.
- settings.py: the Spoolman toggle cleared SpoolAssignment on switch-on
but never cleared SpoolmanSlotAssignment on switch-off. Added the
symmetric clear so stale Spoolman rows can't leak into a later
internal-mode session and mask a real missing-assignment warning.
Adds 3 notification tests + 1 mode-switch integration test. An audit
of the remaining SpoolAssignment consumers confirmed usage_tracker,
spool_tag_matcher and routes/inventory are correctly internal-mode-only.
notify_missing_spool_assignments_on_print_start queried only the legacy
SpoolAssignment table. In Spoolman mode that table is empty -- bindings
live in spoolman_slot_assignments -- so assigned_global_trays came back
empty and every used tray was flagged missing, firing a false-positive
notification on every print.
Union SpoolAssignment + SpoolmanSlotAssignment rows for the printer
before computing the missing set. Both tables expose printer_id /
ams_id / tray_id identically, so _global_tray_from_assignment is
unchanged. Union-only, so legacy-mode behavior cannot regress.
The search bar was rendered only when totalCount > 0, but totalCount is
the sum of the post-filter preset lists. A query that matched nothing
dropped it to 0 and unmounted the search bar along with the columns,
so the user couldn't clear the query without a page refresh.
Gate the search bar on hasAnyPresets (pre-filter count) instead, so it
stays visible as long as any preset is imported. Split the empty state:
"No local presets yet" when nothing is imported, vs a new "No presets
match your search" message when a query filtered everything out.
The Status panel's Low / High thresholds readout was stuck at 0.38 /
0.78 regardless of the Sensitivity dropdown, so the setting looked
dead. Detection itself was correct -- classify() always used the real
sensitivity -- but get_status() computed the displayed thresholds with
a hardcoded thresholds("medium").
get_status() now takes an optional sensitivity argument and the
/obico/status route passes settings["sensitivity"] (it already loads
settings fresh). The readout updates as soon as the change is saved.
Reporter's H2C connected over MQTT+TLS but every status field stayed
unknown. Root cause was layer-8: the MQTT broker is the printer, it
authenticates on the access code and SUBACKs any topic string, so a
wrong or mis-cased serial connects fine and silently receives nothing
(the report topic device/<serial>/report is case-sensitive; Bambu
serials are uppercase). Bambuddy stored and used the serial verbatim.
- schemas/printer.py: field_validator strip()+upper()s serial_number on
create, rejects blank-after-strip. The subscribed topic now always
matches the printer's correctly-cased one.
- bambu_mqtt.py: count report-topic messages per connection; when a
stale reconnect fires with zero reports received, log a one-shot
hint pointing at the serial number instead of looping silently.
Reporter on X2D set a 1h AMS dry; the printer powered off seconds in.
Support log: every "Sent drying command duration=1" was followed 3-9s
later by "AMS 0 drying complete (dry_time 60 -> 0)" -- the completion
callback fired right after drying started, arming smart-plug auto-off.
Root cause: the tray-bearing branch of the AMS partial-update merge
rebuilt the unit as {**ams_unit, "tray": merged_trays}, never spreading
existing_unit. Tray-bearing partials carry no drying fields, so dry_time
(and info) was dropped; the falling-edge detector read the absent field
as 0 and saw a false 60->0 edge.
- Merge: tray branch now spreads existing_unit first, preserving
dry_time / info / humidity / temp across tray-only partials. Matches
the no-tray branch. Also fixes dry_status/dry_sub_status UI flapping.
- Detector: only evaluate the falling edge when dry_time is explicitly
present and parseable; skip otherwise without updating state.
#1447 added computePopoverPosition() to flip the drying popover above
the trigger when below would overflow. Its degraded branch (popover
taller than the viewport) keeps the popover below and its comment
promised "the user can scroll inside it" -- but the popover div was
overflow-hidden with no max-height, so the Start button stayed
unreachable on short viewports.
Make the promise true: the popover is now a flex column capped at
calc(100vh - top - 8px); the body scrolls (overflow-y-auto) and the
header/footer are shrink-0, so the Start button is pinned and always
reachable. Covers the MacBook + iPhone 15 Pro Max PWA cases in #1458.
security.yml had this ignore added in 9d440beb but ci.yml runs its
own pip-audit step with a separate ignore list. CI was still failing
on main + dev. Reasoning identical to the security.yml comment —
disputed by PyJWT maintainers, no fix exists, Bambuddy uses
secrets.token_urlsafe(64) and rejects short secrets.
- requirements.txt: pin idna>=3.15 to clear ReDoS in idna.encode() on
crafted Unicode payloads. Transitive via anyio/httpx/requests/yarl,
so the explicit floor stops a future downstream loosening from
silently downgrading us.
- security.yml: permanently --ignore-vuln CVE-2025-45768 (PyJWT). The
advisory is disputed by the maintainers — "key length is chosen by
the application" — and no fix version exists. Bambuddy is safe:
auto-generates secrets via secrets.token_urlsafe(64) and rejects
file-loaded secrets shorter than 32 chars (auth.py:177, :184).
- security.yml: drop the stale Pygments --ignore-vuln CVE-2026-4539.
Pygments has been patched upstream; the ignore no longer matches
anything.
Step 0 empirical test on 2026-05-20 disproved the "CLI cannot re-slice a
3MF for a different printer" assumption: feeding an 18-color H2D-bound
Trent900.3mf to the X1C bundle via /slice produces valid X1C G-code in
1.8s, with bed (256x256), kinematics, nozzle count, machine_start_gcode,
and bed_exclude_area all coming from the target bundle.
- SliceModal: drop !printerMismatch from isReady; remove the banner and
the sourcePrinterModel / printerProfileName / printerMismatch state
entirely. Cross-printer slicing is now indistinguishable from a normal
slice; the picker already shows the target printer.
- Remove slice.printerMismatch from all 8 locales.
- API cleanup: drop source_printer_model from /library/files/{id}/plates
and /archives/{id}/plates responses, drop the field from
frontend/src/types/plates.ts (PlateMetadata + LibraryFilePlatesResponse),
delete extract_source_printer_model_from_3mf from threemf_tools.py and
its 6 unit tests. Zero remaining consumers.
- i18n discipline cleanup in SliceModal.tsx (same drop): strip every
inline English defaultValue / positional fallback from t() calls (22
sites). Add slice.bundle / slice.bundleNone / slice.bundleAllRequired
to all 8 locales — they had no entry in any locale file and were being
served from the inline English fallback for every non-English user.
- Tests: rewrite the mismatch-warning test to assert "no banner, Slice
enabled" when models differ (regression guard); delete 2 obsolete
tests covering gate states that no longer exist.
Adds BZD with symbol BZ$ to the Settings cost-currency picker so
users in Belize can track filament costs in their local currency
without doing 2:1 USD mental conversions.
Reporter on Postgres + Spoolman saw weight never decremented after
prints. Traced to _report_spool_usage_for_slots calling only
client.find_spool_by_tag() — which returns None when extra.tag is empty.
Non-RFID spools assigned via the Bambuddy UI intentionally leave
extra.tag empty (per #1457 — we don't want fallback tags polluting
Spoolman), so tag-less spools never got matched and weight tracking
silently no-op'd. The tracker never consulted the local
spoolman_slot_assignments table that has the binding.
Adds _resolve_spool_id_via_slot_assignment() as stage 2 of the
resolution chain. Stage 1 (existing tag-lookup) wins when present so
RFID auto-sync remains unchanged. (ams_id, tray_id) derived from
global_tray_id via the existing _global_tray_id_to_ams_slot helper,
so external slots and AMS-HT slots resolve correctly. Threaded
printer_id through the three callers (partial G-code, partial linear,
final-usage report). Resolution path is logged ("via tag" vs "via
slot-assignment") so support bundles confirm the fix is live.
extra.tag is deliberately NOT auto-populated — that would re-introduce
the exact pollution #1457 cleaned up. Slot-assignment table is the
source of truth for non-RFID; extra.tag is reserved for hardware RFID.
Reporter on a P1S with non-RFID spools saw an old, almost-empty spool in
the AMS hover card's "Spulen-ID" block while the "Zugewiesen" block
correctly showed the freshly assigned full spool. Two layers compounded:
(1) Non-RFID slots fall back to a deterministic per-slot tag
(hash(serial) + ams_id + tray_id). The Link / Assign routes wrote
that tag to Spoolman extra.tag but never cleared it from the
previous holder on re-binding.
(2) The frontend's hover-card resolver preferred the (stale) tag-link
over the user's explicit slot-assignment. Same precedence bug in
SpoolBuddy's fill-bar resolver and slot-action picker.
Frontend: swap precedence at 5 sites — slot-assignment outranks tag-link
everywhere. FilamentHoverCard's existing match-dedupe then collapses the
two "Open in Inventory" buttons back into one.
Backend: new _clear_stale_tag_links() in spoolman_inventory.py, called
from POST /spoolman/inventory/slot-assignments (with the slot's
deterministic fallback tag) and POST /spoolman/spools/{id}/link (with
the literal tag being bound — works for RFID and fallback). Best-effort:
Spoolman 5xx and per-spool patch failures log + continue, never wedge
the bind. get_fallback_spool_tag_for_slot promoted to a public helper
mirroring the frontend's signature exactly.
Two bugs in one report, both shipped here.
(1) Popover positioning. The flame-icon onClick on PrintersPage
computed popover position as a fixed { top: rect.bottom + 4,
left: Math.max(8, rect.right - 240) } with no viewport-overflow
check. The flame icon sits at the bottom of the AMS info section
on the printer card, so on most realistic viewports
rect.bottom + 4 + popover_height (~320px) overruns viewport.height
and the popover renders partially or entirely off-screen with the
Start button unreachable. Reporter worked around it via DevTools to
confirm the popover was actually there, just clipped.
Extract a computePopoverPosition() helper in utils/popoverPosition.ts:
- defaults to below + right-aligned to the trigger (preserves the
original visual layout when there's room),
- flips ABOVE the trigger when below would overflow AND above fits,
- stays below in the degraded case (popover taller than viewport) —
at least the top is visible and the user can scroll inside; flipping
to a top-clipped position would lose the action buttons too,
- clamps the left coordinate so a trigger near either viewport edge
can't push the popover off-screen horizontally either.
Both PrintersPage callsites (compact AMS row at :3498 and dual-nozzle
layout at :4011) route through the helper.
(2) Diagnostic logging for the silent-drying-ignore. Reporter's
support bundle shows the printer receives every ams_filament_drying
command (P1S 01.10.00.00 firmware, AMS-HT at ams_id=128) and ACKs
each one, but the AMS info field never changes — drying neither
starts nor stops on Bambuddy's request, while pressing Start on the
printer's touchscreen works immediately. The command JSON matches
the format documented as working on H2D, all required fields present.
Diagnosing the silent rejection needs the printer's actual response
payload — result/reason — but bambu_mqtt.py:918 was only logging the
response command name, not the body. The existing extrusion_cali_* /
ams_filament_setting debug path at :919-920 was the template; this
PR extends it to ams_filament_drying at INFO level (not DEBUG like
its siblings) because drying responses are rare (user-initiated only)
and INFO ensures the body lands in support bundles by default without
the user having to bump log level first. Paired with an outgoing-side
INFO log inside send_drying_command that captures the full wire JSON,
so the next bundle has both halves of the conversation.
No guessing on the command-side. Mutating a field that matches the
documented-working H2D shape (e.g. flipping close_power_conflict)
could break currently-working installs. When the reporter retries on
this build and re-attaches a bundle, the rejection reason is visible
and the command-side fix follows from real data.

This is part 1 of #1447. The functional drying bug — printer receives
the ams_filament_drying MQTT command, ACKs it, but never starts/stops
drying on Bambuddy's request while the printer's own touchscreen works
— is NOT addressed here. Diagnosing it needs the printer's actual
response payload (whether result: "fail" and the specific reason code),
which bambu_mqtt.py:918 currently doesn't log for ams_filament_drying.
Punted to a follow-up where I'll extend the existing extrusion_cali_* /
ams_filament_setting payload-logging path at :919-920 to cover
ams_filament_drying too, ask the reporter to retry, and fix the
command side based on what the printer actually returns.
PrintCalendar.tsx had three instances of the same UTC-shortcut anti-pattern:
1. Bucketing input dates via `date.split('T')[0]` — gives the UTC day
while the cell tooltip rendered local via `toLocaleDateString`. Same
data, two renderers, only one was tz-correct. Reporter on CDT (UTC-5)
saw evening prints jump to "tomorrow's" cell.
2. Per-cell lookup key built via `day.toISOString().split('T')[0]`. The
`day` Date objects produced by the calendar-generation loop are
local-tz (constructed via `new Date()` + `setDate`), so `toISOString`
shifted them back to UTC before the lookup — would have re-broken the
join even after the bucketing fix.
3. "Today" ring comparison used `new Date().toISOString().split('T')[0]`
too — at 23:00 local the ring would have moved to UTC-tomorrow's cell.
Fix adds a `localDateKey(input: string | Date): string` helper to
utils/date.ts that wraps parseUTCDate and formats via the local-tz
getters (`getFullYear` / `getMonth` / `getDate` with two-digit padding),
returning a stable comparable YYYY-MM-DD. PrintCalendar.tsx uses it in
all three spots so the buckets, the cell join, and the today ring share
the same local-tz axis as the user's tooltip label.
Backend stays UTC. Bucketing is a presentation concern and the browser
already knows the user's tz.
Stragglers flagged for follow-up: StatsPage.computeDateRange builds
dateFrom/dateTo for backend stats queries using getUTC* getters, so a
"this week" picked at 23:00 local on Sunday in CDT sends UTC-Monday-based
ranges to the backend. Fixing it properly also needs the backend to
filter on a tz-shifted UTC range, and Bambuddy has no user-tz setting
model today. localDateKey is in place for reuse when that work lands.
The pre-insert MQTT probe added in 0.2.4.2 (b51598ea) had two bugs that
compounded on P1S firmware specifically:
1. Fixed 2-second sleep was too short. P1S broker + TLS handshake
routinely needs 3-5s to surface CONNACK on a cold MQTT session (same
firmware family with the documented "broker stops publishing but TCP
stays alive" quirk at bambu_mqtt.py:3181), so the probe falsely rejected
a printer that would have connected fine. H2C's broker is snappier and
cleared the 2s window without trouble — which is why the reporter's
H2C added without issue and only the P1S misbehaved.
2. client.disconnect() ran synchronously on the asyncio thread.
BambuMQTTClient.disconnect() ends in paho's loop_stop() which joins
the network thread; if that thread was still mid-TLS-handshake to the
slow P1S socket when teardown ran, the join blocked the asyncio thread
for as long as the handshake took to complete or fail. POST /printers
wedged, every other HTTP request queued behind it, Docker healthcheck
timed out — user-visible symptom: "the container hangs."
Fix:
- Replace the fixed sleep with a polling loop (8s budget, 200ms tick,
early-returns the moment state.connected flips True). Slow brokers
get the headroom they need; happy-path connects still finish in
~1-2s. Constants exposed as PROBE_TIMEOUT_SECONDS / PROBE_POLL_
INTERVAL_SECONDS class attributes so tests can dial them down.
- Move client.disconnect() to await asyncio.to_thread(...) so paho's
thread-join can never block the event loop.
The empty-card-report-prevention goal of the original probe stays
intact: a genuinely wrong access code still results in connected=False
after the 8s budget, the 400 with code=printer_connection_failed
still fires, the row is still never persisted.
PrintLogEntry.failure_reason is captured once at print-completion time
(main.py:3641) by copying archive.failure_reason — which is NULL while
the user hasn't classified the failure yet. The PATCH /archives/{id}
route then writes only to print_archives via a generic setattr loop,
so the log entry stays NULL and failure_analysis.py keeps grouping the
print as "Unknown". Same desync hits status — flipping it in the modal
never reached the entry either.
Mirror failure_reason and status from the PATCH payload to the latest
PrintLogEntry for that archive (highest id). Latest-only because
archive.failure_reason / status already reflect the latest run's outcome
(each reprint clears the archive value at main.py:2195 and rewrites it
at completion), so the Edit Archive modal is implicitly editing the
latest run — reprints of an archive that succeeded on the second attempt
keep the earlier failed run's original classification intact.
Scoped to those two fields only. cost / print_name / printer_id stay
unmirrored because per-run values legitimately diverge from archive
ones (partial-print cost on a failed run vs source archive's full-print
cost — see _compute_run_filament_grams at main.py:596).
Two bugs surfaced by @flom89 in the same thread:
(1) The Write-Tag page hardcoded api.getSpools and friends regardless of
inventory backend. Users in Spoolman mode saw internal spools they never
created and a successful tag write would have bound the NFC tag to the
wrong backend (the backend write-tag route is mode-aware; the frontend
was driving it with the wrong IDs). Fix follows the InventoryPageRouter
pattern: detect spoolmanMode from getSpoolmanSettings, gate the spool
fetch on spoolmanModeReady to avoid the initial wrong-backend request,
and branch all 6 API call sites (list, autocomplete, untag, K-profile
save, single create, bulk create — the bulk variant returns a different
envelope shape so the duck-typed check from SpoolFormModal is mirrored).
(2) The spool ID was missing from three more SpoolBuddy components
beyond the first round of #1439 work — SpoolInfoCard (the dashboard's
right-side found-tag panel — the "main screen" view the reporter named),
InventorySpoolInfoCard, and SpoolBuddyAmsPage's assigned-spool block.
Same #1385 pattern (#<id> in muted small monospace with shrink-0).
Python 3.13 negotiates TLS 1.3 by default. The P2S firmware 01.02.00.00
vsFTPd build doesn't tolerate TLS 1.3's async session-ticket model on
the FTPS data channel — session resumption races, the data channel gets
torn down mid-stream, uploads land truncated at a chunk boundary, and
the printer replies 426 instead of 226. Visible to the user as "unable
to parse 3mf file" 30 s into the print.
Capping the SSL context's maximum_version to TLS 1.2 makes session
resumption synchronous and uploads complete normally.
Follow the per-model pattern established by camera_profiles.py in the
#1395 follow-up: add backend/app/services/ftp_profiles.py with a frozen
FTPProfile dataclass and a per-model registry. Only P2S (display name
+ N7 SSDP code) gets the cap today. X1C, H2D, P1S, A1 stay on negotiated
TLS 1.3 — the maintainer's dogfooded printers see zero behaviour change.
The browser-side 3MF parser in ModelViewer.tsx runs entirely on the main
thread (JSZip extract + DOMParser + vertex/triangle iteration), and Bambu's
external-component shape chains one of these per part. Multi-color parted
statues from MakerWorld can spend tens of seconds in straight-line JS,
during which the modal close button can't fire and the browser shows
"page unresponsive".
Add nextTick() yields at four hot spots:
- every 20 000 vertex iterations inside parseMeshFromDoc
- every 20 000 triangle iterations inside parseMeshFromDoc
- the matching loops in parse3MF's direct-mesh path
- once per top-level <object> iteration in parse3MF
- once per <component> iteration in parse3MF
This doesn't make parsing faster — it surrenders control to the browser
between batches so the modal stays interactive. Proper Web Worker refactor
is a tracked follow-up.
The snapshot-diff strategy in _scan_for_timelapse_with_retries needs
_timelapse_baselines[printer_id] populated at print start so the
completion-time scan can find the new MP4 by set-difference (mtime is
unreliable — LAN-only printers don't sync NTP).
The baseline-capture call was only in on_print_start's new-archive branch.
Queue / VP-dispatched / reprinted jobs take the expected-archive branch
which returns earlier, so the dict stayed empty and the completion-time
scan fell into the "take baseline now" fallback that snapshots after the
new file has already landed — no diff ever matches.
Extract the snapshot into _capture_timelapse_baseline_at_start and call
it from both branches.
PR #1434 CI flagged 5 B402 (ftplib import) in test_bambu_ftp.py and 2
B108 (hardcoded /tmp) in test_print_start_assigns_printer_id_to_vp_archive.py.
Both are intentional in tests: the FTP client tests need real ftplib
exception classes to construct mock 426 responses, and the /tmp path is
a MagicMock attribute never written to. Marked with `# nosec B402` /
`# nosec B108` plus a one-line justification each, matching the
convention from c2630399.
