After an RTSP session dropped, ffmpeg could keep writing the same JPEG
indefinitely with no connection to the printer left (two hours at ~29 fps
on a P2S), and every check that counts frames saw a healthy stream. The
stream now restarts ffmpeg after 20 s without a changed frame, on the
existing reconnect path, while viewers stay attached. If the first frame
after the restart is the same picture again, the camera really shows a
still scene (a dark, idle chamber): it is then only re-checked every
5 minutes until the picture changes.
OrcaSlicer's Sync filaments finds a slot's preset by the slot's filament
ID alone. The Configure dialog looked up an Orca profile's ID in the
browser and quietly sent the generic for the material when that came back
empty, so Orca custom filaments reached the slicer as Generic and the log
showed nothing. configure now resolves the ID on the server from
orca_profile_id, follows inherits to the parent profile or the Bambu
filament it was copied from, logs the outcome and reports a fallback,
which the dialog shows as a warning.
Slot presets also store the filament ID they were written with, so the
slot card and the Configure dialog stop showing a preset once the slot is
changed from OrcaSlicer's Device tab or the printer.
Re-configuring a slot for another filament no longer carries over the old
filament's active K-profile, which switched the slot back to the old
filament.
Fetch a signed feed.json from the public bambuddy-notifications repo on
GitHub at startup and every 6 hours. Nothing about the install is sent;
targeting (version, beta channel, install type) is decided locally.
- Ed25519 against a key built into the app; an older serial is refused so a
withdrawn message can't come back. The feed replaces the stored list, and
a failed or rejected fetch keeps the last good one.
- Sidebar entry above System with an unread count, a slide-over list, and a
banner for unread important/critical messages. Read state per user.
- Admins by default; Settings > General > Updates can show them to all
users or switch them off, which also stops the fetch.
- Plain text only; links to github.com and bambuddy.cool only.
ams_get_rfid was published and reported as success without reading the
printer's answer. X1Plus on base 01.08.02.00 answers FAIL / ERROR STATE,
so the user saw "Refreshing" and the K profile was re-applied to a slot
that was never read.
- Wait for the ams_get_rfid answer (matched by sequence_id).
- On a refusal from an idle X1/P1/A1, send the legacy M620 R<ams*4+slot>
gcode Bambu Studio uses for those models, AMS units 0-3 only. Never
during a job, never on newer-protocol models; printers that accept
ams_get_rfid never see it.
- Refused: the route returns 400 with the printer's reason and no PA
re-apply is scheduled. No answer still counts as accepted.
- Log the answers at INFO so refusals reach support bundles.
lldap and OpenLDAP's memberof overlay omit memberOf from "*", so every
lldap login fell through to the default group. Request memberOf by name
when the schema defines it, and on non-AD directories also search the
directory root for groupOfNames/groupOfUniqueNames entries listing the
user, since groups often sit outside the user search base and the
overlay tracks only one group class.
Also: skip ldap3's anonymous schema read after StartTLS, which AD and
Samba AD reject, so StartTLS works there; reword a server's StartTLS
refusal with an LDAPS hint; stop the bundle sanitizer masking part of
an OID as an IP; skip the sync right after auto-provisioning so the
default-group warning logs once.
Spoolman keeps a full spool's net weight on the spool (initial_weight)
and falls back to the filament's weight, but Bambuddy read only the
filament, so a 250 g spool of a 1000 g filament showed and synced as
1000 g. The list, weigh, AMS sync, SpoolBuddy scale, remain-% tracking,
fill bar and cost now share one lookup. Create writes initial_weight,
and a label-weight edit writes it instead of patching or duplicating the
filament. The spool form's cost per kg is converted at the spool's size
to and from Spoolman's per-spool price.
Spoolman resolves a spool's tare from the spool, then the filament, then
the vendor's empty_spool_weight. Bambuddy skipped the vendor and fell
back to 250 g, so weighing a spool whose tare was set only on its vendor
gave the wrong remaining weight. The inventory weigh action, the
SpoolBuddy scale and the displayed core weight now share one lookup, and
"keep old weight" on a filament change stamps a vendor-inherited tare.
A PUT /settings with null for a number setting stored the literal
"None". From then on int()/float() raised inside the response builder,
and every settings read returned 503 until the row was fixed by hand.
Explicit null for any boolean or numeric setting is now refused with a
422 that names the keys, and nothing in that request is saved. A numeric
row that does not parse reads back as its default with a warning, so an
install that already stored one recovers. The typed-key lists moved to
module constants so the save check and the read path share them.
POST /notifications/app-message delivers an app's message to every channel
with the new "Messages from connected apps" switch on (off by default),
through quiet hours, the digest and the log. API keys need the new "Send
notifications" permission, and their owner notifications:update; plain text,
http(s) links, 20 messages a minute per key. The electricity-price door and
this one now share one scoped-key check. /queue?batch=<id> opens and
highlights one batch order.
Minimal OAuth 2.0 authorization-code flow with PKCE (S256): admins register
an app with one exact callback URL (Settings > API Keys > Connected Apps);
/connect/authorize asks for consent once and returns a single-use, 60 s code
bound to app, callback and challenge; POST /api/v1/connect/token swaps it,
with the client secret, for the user's identity and permissions. Codes and
secrets stored hashed, exchanges rate-limited per client and IP, no redirect
before the callback is validated, API keys cannot authorize, refused while
auth is disabled. i18n for all 15 locales.

fix(db): upgrading from 0.2.4.0 or older no longer crashes at startup
The #2974 failure-reason conversion ran before the #1378 migration that adds
print_log_entries.failure_reason, so older databases stopped with "no such
column: failure_reason". It now skips a table without the column, only runs
where a legacy label exists, and on SQLite rebuilds archive_fts first, since
archives created before that index existed trip "database disk image is
malformed" when updated.
POST /queue/batches accepts external_source + external_ref; both are
returned on every batch and filterable on GET /queue/batches. The pair is
unique (index uq_print_batches_external), so a retried create answers 409
instead of queueing the same order twice. Migration covers SQLite and
PostgreSQL.
Follow-ups after merging PR #3128 (with the #2990 preview work):
- PDF preview failed on every browser without
Map.prototype.getOrInsertComputed (Chrome < 145, Firefox < 144,
older Safari): "This file cannot be previewed" for any PDF. Load
pdf.js's legacy build, which bundles the polyfills for page and
worker, and bundle the worker through Vite (?worker&url) so
build.target lowers its class static block for Safari 16.0-16.3.
The browser-baseline check only scanned .js output and never saw
the copied .mjs worker; it scans .mjs too.
- PDF grid thumbnails only existed after someone opened the preview.
Page one is now rendered server-side with PDFium (pypdfium2, new
dependency, prebuilt wheels for every shipped platform) on upload,
ZIP extraction and external-folder scans; Generate Thumbnails
backfills PDFs as well. Renders are serialised behind a lock
(PDFium is not thread-safe), run off the event loop, and scale
from the page size so a huge MediaBox cannot allocate a huge
bitmap. Unreadable PDFs land without a thumbnail and keep the
browser fallback.
- A large STEP file takes over a minute to mesh in the browser and
showed only a spinner. STEP loads now show "Converting STEP
model... N s" and a note that large files can take a minute or
more, in all 15 locales.
- Drop the two occt-import-js "externalized for browser
compatibility" build warnings (path/crypto are only required in
its Node branch); any other externalization still shows.
Bambu sends two humidity fields that are not the same quantity.
humidity_raw is relative humidity in percent; humidity is a 1-5 drop
index, and it runs the other way -- OpenBambuAPI's push_info sample
pairs "humidity:30%" with "humidity_idx:4", so a high index means dry
where a high percentage means wet.
Four call sites used the index whenever no percentage arrived. A unit
sending only the index therefore rendered as "2%" in the green band
while being the second-wettest of the five steps, charted an average of
index values as a percentage, and sat under every humidity threshold
forever, since no index can reach one -- the alarm and auto-drying could
not fire for such a unit at all.
- utils/ams_humidity: one leaf helper, a percentage or None. The index
is never converted; None is what every caller already handles.
- routes/printers, printer_manager, print_scheduler, main, bambu_mqtt:
all five readings go through it, so the card, the websocket, the
chart, the alarm and auto-drying cannot answer differently.
- main: a unit that reports the index and no usable percentage says so
once per unit in the log, with its firmware versions requested. No
supported printer is known to do this, and "known" is doing work
there -- the alternative is a card that goes blank with no trace.
Three faults found while checking what else those paths touched:
- main: humidity_raw=float(x) if x else None stored NULL for a numeric
0% while writing 0.0 to humidity on the same row.
- main: that same expression was unguarded, unlike the parse above it,
so a non-numeric humidity_raw raised inside record_ams_history and
aborted the pass for every printer, not just the one that sent it.
- routes/ams_history: the averages were tested for truthiness, so a
window averaging exactly 0 reported no average while the min and max
beside it reported 0.0.
An affected unit now reports no humidity rather than a number that means
the opposite: the indicator is hidden, the chart leaves a gap, the alarm
and auto-drying skip the unit. Temperature is untouched. Auto-drying's
outcome is unchanged either way -- an index could never cross the
threshold -- so only the intent moves.
No supported printer is known to be affected; the report came from an
install running X1Plus, which Bambuddy does not support. Verified
against 7927 recorded samples from seven AMS units including an AMS-HT:
not one used the fallback. Two percentages that did fall through to the
index no longer do -- a reading with a decimal point, and "38.0", which
int() rejected.
print_archives.library_file_id -> library_files.folder_id ->
library_folders.archive_id -> print_archives. Three nullable SET NULL
links, each reasonable alone, that together made a loop
metadata.sorted_tables could not sort: it dropped those edges, warned on
every backup and every restore, and could return an order placing a
child before its parent -- which once imported library_files ahead of
library_folders and killed a restore on a ForeignKeyViolation.
The restore no longer depends on that order (it strips every foreign key
before importing and adds them back after), but the backup export sorts
the same way, and the warning ends with "may raise an error in a future
release" -- which would break backup and restore on one upgrade.
Marking one edge use_alter removes it from the sort graph, not from the
database: PostgreSQL emits it as ALTER TABLE ADD CONSTRAINT, as it
already did for every constraint on these three tables, and SQLite
inlines it into CREATE TABLE, so ON DELETE SET NULL holds on both.
Verified against PostgreSQL 16 and SQLite.
The post-slice thumbnail loaded the sliced 3MF with trimesh, whose reader
mishandles the Bambu Studio / OrcaSlicer layout: for every component that
references a file in 3D/Objects/ it re-parses that file and appends all
of its meshes again. N copies of a part came back as N^2 copies of its
triangles, and each component carried every other part of the same file.
25 bins of 10k faces loaded as 6.4M faces; the render took 54 s and
8.4 GB on the event loop, and the server was OOM-killed.
Parse the 3MF directly (lxml, entities/DTD/network off, streamed and
freed element by element), walk objects, components and build items
(p:path on either) with their transforms, and keep each mesh once.
Decimate per unique mesh to its share of a face budget before placing
instances, flip winding on mirrored placements, and skip the thumbnail
above a face ceiling checked both on what decimation can reach and on
what it delivered.
Both slice routes run the render in a thread. The renderer uses
matplotlib's Figure/Agg API instead of pyplot, whose process-global
figure state let a threaded plate render and stl_thumbnail's
event-loop render lay out and close each other's figures.
Switching an "Any P2S" job to a specific P2S cleared its filament
override: "Specific Printer" empties the target model and the reset
effect counted that as a model change. Printer mode also matched trays
against the 3MF's colours, never sent the override, and left the old one
on the row.
The reset now compares against the last model actually targeted, so the
switch keeps the override while a real model or plate change still clears
it. Printer-mode tray matching (single, per-plate, multi-printer and the
selector's per-printer editor) runs against the requirements with the
overrides applied, mirroring the scheduler's _apply_filament_overrides; an
entry naming the slot's own filament is not a swap and keeps its
tray_info_idx. Printer-mode submits carry the user's overrides, and the
create endpoint stores them for a printer-targeted job, so a dispatch-time
recompute of an unresolved mapping looks for the same filament.
Saving re-attaches the tray_info_idx an unchanged entry already had, so a
virtual printer's force-colour PLA-variant pin (#2650) survives an edit in
either assignment mode. The printer card's compatibility filter skips
printer-targeted jobs: it mirrors the model scheduler, and hiding a job on
filament would hide it from the printer it is going to run on.
Selecting sliced files for two printer models and asking for 25 copies
queued one item. The queue emptied as soon as it dispatched and the
Batches tab stayed empty, because no batch is created at quantity 1.
A multi-plate file moves the run count off the modal's Quantity field
onto a stepper beside each plate (#342), hiding the field. The
cross-model submit (#671) posts that field, which in this combination
nothing can set, so it stayed at its initial 1. The modal read "19 runs
in total" above a button that queued one.
Per-plate steppers do not fit a cross-model job: its plate is chosen per
candidate, in the alternatives list, so there is one number to give.
Exclude cross-model from the per-plate mode and the global field comes
back.
Drop the plate selector in that mode too. Its choice never reached the
request; it only keyed the filament-requirements query, so picking plate
3 for a candidate while plate 1 stayed ticked above produced overrides
computed from a plate the job would not print. That query now follows
the primary file's own dropdown.
Dispatch needed nothing -- it already gives each copy its own candidate
rows -- but naming did. A cross-model job carries neither archive_id nor
library_file_id, because the candidates are the files, so both branches
that name a batch missed and every such order would have read "Batch" in
the tab the reporter went looking in. Name it after the first candidate.
The existing cross-model tests all mock a single-plate file, which is
why the pair was never covered; the multi-plate case is added.
Bambu Studio files a sliced print on the X2D's internal eMMC, which FTPS
does not serve. The bounded probe found a same-named file on the card --
an earlier slice of the same project, plate 4, against a running plate 1
-- and #1204's guard correctly refused it rather than archive another
plate's thumbnail, filament and cost.
It then blanked subtask_name because swap_plate_suffix returned None. But
None also means "this name carries no plate suffix", and such a name holds
no stale plate number to be wrong about. The project name was dropped, the
row fell through to the gcode_file path, and the archive was titled
plate_1.
Keep the name for the title only. subtask_name itself stays disowned,
because it is what every lookup here is built from and it keys
_active_prints, where the cover endpoint's own download of that same name
would find this archive and hand the contradicted file to
_recover_fallback_archive -- which checks a candidate is a readable 3MF
and never which plate it holds. A corrected name is still registered:
that one points at the plate actually running.
Also name the X2D alongside H2-series and P2S in the Archives banner, the
connection diagnostic and the storage-verdict docs -- it stores slicer
sends the same way, and an X2D owner was told the explanation did not
apply.
The two tag-link routes answered the same conflict differently. The
built-in one said "Tag UID already linked to another active spool" and
named nobody -- while holding the conflicting spool row it had just
loaded -- and Spoolman mode named the spool inside a different English
sentence. Neither was machine-readable, so a client had to parse prose
to learn which spool to look at, and could only do it in one mode.
Both now raise one shared constructor: code tag_already_linked, the
holder's id, and which identifier collided. That is the detail shape
insufficient_filament and printer_connection_failed already use, so
ApiError parses it with no frontend change.
Two active spools can carry one tag -- no unique index on either
column, no conflict check on PATCH /spools/{id}, and /spools/bulk
copies one payload including the tag into every row it creates -- and
the lookup read that with scalar_one_or_none(), which raises on two
rows. The exception escaped into the auth middleware's fail-closed
handler, so the caller was told the authentication service was
unavailable. Both lookups are now ordered and take the first row, as
get_spool_by_tag earlier in the same file always has.
Naming the lowest id means the Spoolman scan reads every row where it
used to stop at its first match, so it now reads extra.tag defensively:
that field is edited outside Bambuddy, and a single null further down
the list would otherwise take the request down in place of the 409.
The kiosk reads the new code: a refused link showed a flat "Failed to
assign spool" and now names the spool holding the tag, reusing the
inventory.tagAlreadyLinked key that no code referenced.
Swapping a Bambu spool for one the AMS cannot read left Assign Spool
publishing no ams_filament_setting at all. The printer kept showing "?"
on its screen and in the slicer, and only Configure, which publishes
unconditionally, put anything there.
Four places asked the tray's `state` field whether a spool was in the
slot. It cannot answer that. An AMS-HT reports its LOADED tray as 9
rather than 11, because it does not feed into a shared buffer the way a
4-slot AMS does -- the merge has skipped its own state heuristic for HT
units since #2594 for exactly this reason. And the field is partly our
own writing: apply_tray_exist_bits stamps state=9 on every slot whose
tray_exist_bits bit is 0, and when the bit comes back it refreshes only
the `exists` annotation beside it. Either way the slot sits at
exists=True, state=9 until something configures it.
That 9 also kept the deferred-configuration replay from firing -- its
own "has a spool appeared" test was the same heuristic -- which is the
deadlock #1322 removed from the assign path, still in place one step
further along. And it is what deleted the assignments in #3100: with the
replay never firing, the row kept the empty fingerprint it was stored
with, and the first tray report naming a filament was read as a swap.
All four now read tray_exist_bits first, which is the mask firmware
answers this question with and the one the printer card has drawn its
"?" from since #2527. The bit is allowed to overrule an "empty" state
and nothing else: a bit reading empty deliberately does not start
suppressing pushes that go out today, because the cost of computing a
bit position wrong is a slot that silently stops configuring, against a
saving of one message firmware would have dropped.
A blank tray report from a slot the bit calls occupied no longer unlinks
anything, off a print as well as during one, in both inventory modes --
Spoolman's parse_ams_tray calls a tray with no type empty, so a tag-less
spool assigned through the UI had its row deleted by the first idle push
after it went in. A filament the AMS cannot identify is not a filament
that was removed.
The Finance page was the only surface in Bambuddy that read its currency
from a data row rather than the `currency` setting, and it fell back to EUR
where every other page falls back to USD. One variable drives every amount
on that page, so the personal balance, the cost-center budgets and the whole
transaction list were wrong together on any install not set to euros. It now
takes the configured currency from /settings/ui-flags, which is readable by
anyone who can see Finance -- /settings needs SETTINGS_READ, which a
cost_centers:read_own user does not have.
The backend was the other half. Of the four places that settle on a
currency, three wrote a hardcoded "EUR": the wallet the API mints on demand,
the wallet a print charge mints when none exists, and the balance returned
for a user with no wallet row at all. All four now go through one resolver,
which lives beside the rest of the balance logic.
The wallet's currency column is removed outright rather than merely ignored.
An install has one currency and nothing here converts between them, so a
per-wallet copy could only ever drift from the setting -- and a column
nothing reads is a trap for whoever finds it next. A startup migration drops
it on both SQLite and PostgreSQL, after the raw CREATE TABLE that would
otherwise re-add it on an install whose finance tables predate the ORM.
SQLite builds older than 3.35 have no DROP COLUMN and keep it, harmlessly,
since it has a default and no reader.
Saving settings now invalidates the ui-flags query too. Nothing did, so a
changed currency sat behind that query's staleTime before showing up. The
sponsor prompt's own EUR fallback is now USD, matching AppSettings.
