The rack card shared a row with the nozzle, bed and chamber readings but
was set to flex: 2 1 190px -- a 190px floor plus twice their growth share
-- to draw six fixed 28px chips. On anything wider than a compact card it
claimed several hundred pixels and left most of them empty, and the width
came out of the cards that needed it: the combined dual-nozzle reading was
wrapping "220 / 220" onto two lines beside a mostly blank rack. It is now
flex: 0 1 auto, so it takes its content width and gives the remainder
back. Shrink stays enabled so it still gives way on a narrow card instead
of overflowing.
Each slot also carries its physical rack position 1-6 below the chip, so a
nozzle can be named rather than counted along. The numbering is positional
-- an empty slot keeps its number -- so "the nozzle in slot 4" means the
same thing however many of the six are occupied.
The #943 regression test read every span in the slot row, which the new
number spans would have interleaved with the diameters; it now matches the
diameter spans specifically. A second test pins the 1-6 labelling across a
rack with empty positions.
Three follow-ups to #2804, all bearing on one decision: which spool a print
uses when the exact colour is not loaded.
Colour ranking is now perceptual. The ranking added in #2804 measured RGB
distance, which rates a colour by how far apart the numbers are rather than
how far apart they look, and it overweights blue badly enough to invert the
answer: against a required #1E4821 green, a purple #38202F is the nearer of
two eligible spools by RGB and four times the further once measured properly.
Both sides now use CIEDE2000 -- perceptual_color_distance in
backend/app/utils/color_utils.py and colorDistance in amsHelpers.ts, kept
structurally identical so they can be read side by side. Verified against the
Sharma/Wu/Dalal published reference set, all 31 pairs to 1e-4, and the two
implementations agree to within 1e-9 across 800 sampled pairs. Eligibility is
untouched, still the per-channel RGB box, so this only reorders spools that
already qualified.
Type matching now agrees between the interface and the scheduler. Bambu
firmware treats PA-CF, PA12-CF and PAHT-CF as one material and the scheduler
has always matched them accordingly, but the interface compared raw type
strings and called that same pairing a mismatch. The badge contradicted what
the printer was about to do, and the manual override picker, which groups by
canonical type, offered the very spool the badge then rejected. The fifteen
comparison sites in useFilamentMapping.ts, useMultiPrinterFilamentMapping.ts
and PrinterSelector.tsx now call filamentTypesCompatible.
The pipeline pre-flight reads the matcher's table instead of its own copy.
That copy had drifted into disagreeing in both directions: it aliased PLA
Basic to PLA where the matcher never has, so a run could clear the check and
then fail to map its slots, and it lacked the nylon grouping, so it flagged
runs the matcher handles without complaint. A check whose job is to predict
dispatch is wrong whenever it disagrees with dispatch, whichever way it leans,
so it and the scheduler now both read backend/app/utils/filament_types.py.
That canonicaliser deliberately does not strip surrounding whitespace. It
looks like a free improvement, but it would collapse a junk tray_type to ""
just as a 3MF declaring no filament type yields "", and a typeless requirement
would start matching a junk-typed tray instead of reporting the slot unmapped.
Padded type strings are worth handling on their own terms, with that case
addressed.
One behaviour change outside the ranking: the pre-flight is stricter for a
printer reporting a product name such as "PLA Basic" where the generic
material belongs, which it now flags rather than passes. Rare in practice,
since the printer reports material and product name in separate fields, and it
is the answer the matcher would give. Nothing about which spool a print
actually uses changed outside the colour ranking itself.
Adds 203 backend and 6 frontend tests. The #2804 tie-break test now uses
identical colours: two colours at equal RGB distance are not perceptually
tied, which is rather the point.
Five header buttons in a row that could neither wrap nor shrink came to
~600px, so on a 390px screen the header ran past the viewport and took the
whole page with it -- <main> is the scroll container, so everything inside
it panned.
Stack below sm and wrap the actions, matching the pattern the Statistics,
Settings and Archives headers and this page's own filter bar already use.
Identical at >=640px. The System Information header had the same
construction with one button and gets the same treatment.
The parts of a form control the browser draws itself -- a number input's
stepper, a date field's calendar button and popup, a select's dropdown,
scrollbars, the autofill tint -- were painted in the light appearance on
every theme. Bambuddy switches theme by swapping CSS variables under a
`dark` class, which the browser cannot see, so it assumed the page was
light and matched the steppers to a white background that was not there.
Declaring color-scheme alongside the variables fixes all of them at once,
in both directions. It goes on `.dark` rather than the per-palette
classes because the kiosk sets `dark` on the root element directly.
Three date and time fields had been pinned to dark by hand to work
around this and no longer need to be; being pinned, they were wrong
under the light theme anyway.
Previewing a sliced multi-plate 3MF from the File Manager showed a plate
nobody picked. The library route took no plate parameter at all, so the
one the viewer has always put in the URL was dropped -- FastAPI discards
unknown query parameters silently. Both routes then fell back to the
first .gcode member of the zip, and member order is whatever the slicer
wrote: the reported file stores plate_2.gcode ahead of plate_1.gcode.
Nothing that opens the viewer from the File Manager passes a plate, so
there was no way to ask for another one either.
Plate resolution now lives in threemf_tools and both routes share it.
select_plate_gcode_name() returns the named plate or None, so a caller
serving an explicit choice can 404 instead of rendering something else;
default_plate_gcode_name() returns the lowest-numbered plate. The viewer
gained a plate switcher, and keeps the choice in its URL so a link to one
plate survives a reload. Filament colours follow it too -- they were
taken from the first plate regardless of which one was on screen.
G-code injection and the finish-photo max_z_height read shared the old
first-member fallback and now resolve the lowest plate as well.
The dialog weighed each plate against the spool in the slot it mapped to
and knew nothing about AMS Filament Backup, so a two-plate job needing
1441 g of ABS was refused against a 1000 g spool while the identical full
spool in the next slot went uncounted. The dispatcher has pooled matching
spools since #1762 and would have run the print -- "Print anyway" was
always the right answer to this warning.
The rule for which spools back each other up now lives in one place:
build_slot_materials() in filament_deficit, which the dispatcher's pool
and the new slot_materials half of GET /printers/{id}/inventory-remain
both draw on. The dialog groups on the keys it is handed rather than
resolving spools a second time, which is what let the two answers drift
apart, and which also gives the check to Spoolman users -- it read the
internal inventory only, so in Spoolman mode it approved everything.
Where a pool really is short the warning quotes the pooled totals, since
the per-slot figure reads as a contradiction next to a full peer spool.
Bundle import was withdrawn in 0.2.5 and the panel was kept behind as a
static notice pointing at the alternatives. It has been on screen for
several releases, it was shown to everyone running the slicer sidecar
whether or not they had ever imported a bundle, and it was a card in
Settings -> Queue & Dispatch that could not be acted on. Component,
render site and all thirteen locales' strings are gone; no slicing
behaviour is touched.
Four docstrings still described the removed feature as a live fallback:
SliceModal was said to fall back to "the user's uploaded Slicer Bundles"
when a preset carries no compatible_printers. There is no bundle model
and no bundle endpoint left -- the actual fallback is the @BBL <code>
printer-model registry, which is what SliceModal has been doing since
Removing the card left the left column of that tab noticeably longer, so
G-code Injection moves to the foot of the right column. The card is
unchanged and keeps its card-gcode anchor, so settings search still
jumps to it.
slice_and_persist always wrote to get_library_files_dir() while giving the
new row the source folder's id, so slicing a file on a NAS mount produced
a .gcode.3mf that showed up in the right folder in the UI and never
reached the share -- invisible from the web UI, which is why it did not
reproduce.
Resolve the destination from the target folder like uploads (#1112) and
moves already do, set is_external and store the absolute path. Collisions
uniquify to "Model (2).gcode.3mf": a 409 would throw away minutes of CPU
on a routine re-slice, and overwriting a file on someone's NAS is worse.
An external folder that cannot take the file (read-only, unreachable, not
writable) falls back to managed storage rather than discarding the slice,
and reports why on SliceResponse.external_write_fallback -- surfaced as a
warning toast. Silent fallback is what made this bug invisible.
Every item in the collapsed header was flex-shrink-0, so the row was as
wide as its contents and the Card doesn't clip -- the remote-interface IP
and the enable toggle painted outside the card border. The name's
`truncate` couldn't save it: a flex item defaults to min-width:auto, so
it never shrank below its text (`flex-shrink-0 truncate` on the target
name was self-cancelling for the same reason).
Move the metadata into a flex-1 min-w-0 flex-wrap group so it wraps to a
second line, and keep the chevron, dot and toggle outside it. Wrapping
rather than truncating: the bind and remote-interface addresses are what
the page exists to show.
Needs three things at once, hence the report -- both IPs set (Bambuddy
and printer on different subnets), a target named "Printer at <ip>" from
discovery, and the 3-column card grid.
overflow-hidden is scoped to this card, not added to Card: half the cards
in the app render menus that deliberately paint outside their bounds.
The Slice action appeared on .step / .stp and the endpoint accepted the job,
but neither slicer can load one from its command line -- both answer
"Unknown file format. Input file must have .stl, .obj, .amf(.xml) extension."
So the file was read, converted and uploaded before failing as "The input
model file to the slicer can not be parsed", which reads as a corrupt model
rather than an unsupported format.
The endpoint refuses a STEP up front with a message saying to export it as
STL or 3MF, and the Slice and pipeline buttons no longer appear on one.
Open in Slicer is unchanged and still hands STEP to the desktop application,
which opens it fine -- that was always the working path. isSliceableFilename
(desktop) and isApiSliceableFilename (sidecar) are now separate predicates so
the two cannot drift back together.
Archives, the queue and statistics report ownership as a numeric
created_by_id, and statistics accept it as a filter, but nothing let an
API key discover whose id was whose -- the only user listing returns
emails, roles, group membership and full permission sets, so it is
administrative and rejects keys.
Add GET /users/slim returning id + username only, gated on a new
users:read_slim permission mapped to can_read_status. That grants no
data a key could not already reach: for API-keyed requests the
permission deps return None as current_user, so the stats:filter_by_user
guard short-circuits and ?created_by_id=N is already honoured for every
N. What was missing was the ability to address the filter, not
permission to use it. The full listing stays unmapped = admin-only.
Also fix /auth/me, which answered an API key with a synthetic
administrator: id 0, role admin, is_admin true and every permission in
the enum. A key cannot reach an administrative route at all, so clients
building their UI from that response rendered actions that 403 on use.
It now reports the key owner's identity, is_admin false, and the
permissions the key's scopes actually admit. Ownerless legacy keys keep
id 0 but no longer claim admin.
---
Source user names from the slim listing where only names are needed (#1894)
Stats filter-by-user, the Archives print log filter, the File Manager
username autocomplete, the camera-token owner column and the Finance
member picker all render nothing but a username, but all of them read
the full user listing, which is gated on the admin-level users:read.
An operator granted stats:filter_by_user but not users:read got an
empty filter with no indication why.
Point them at /users/slim under a separate react-query key, since the
full listing shares the 'users' key and the two shapes would clobber
each other in the cache.
Back-to-back prints in chamber-heated materials (ASA, ABS, PA, PC) each paid
a full heat-soak from cold, even when the print that just finished had left
the chamber at temperature. Two changes remove that cost.
Keep bed warm between prints
While a printer sits in FINISH awaiting plate-clear and the next queued item
needs chamber heat, hold the bed hot so the chamber does not cool during the
bed-clearing window. The bed is the chamber's heating element here, not a
print surface, so the hold runs at the new `queue_keep_warm_bed_temp`
(default 90C, which also satisfies bed-threshold-linked aftermarket chamber
heaters), raised to the item's own bed temperature when that is higher.
Gated on `queue_keep_bed_warm` AND `require_plate_clear` AND
`preheat_enabled`, all re-checked in the backend so a stale UI cannot leave
the feature running. `queue_keep_warm_max_minutes` (default 120) bounds the
hold: when it elapses the bed is switched off and the hold latches until the
printer is next a candidate, so a plate nobody clears cannot leave the bed
hot indefinitely. The hold is also released when the item is deleted, the
queue empties, or a gate is toggled off mid-hold, and never when firmware
reports a target other than the one it set — a temperature the user or a
print changed is left alone. Publishing is idempotent.
Smart soak reduction from chamber history
The scheduler samples each connected printer's chamber temperature every tick
into a 2h rolling history. Preheat credits time the chamber has already spent
at temperature against the configured soak, shortening or skipping it.
Credit starts no earlier than the newest sample, the most recent unbroken run
of samples, or the end of the last real dip below target. A dip only counts
once it outlasts a grace period: an enclosed chamber cannot lose and regain
several degrees quickly (measured on an X1C, cooling from 55C to below 48C
takes 23-73 minutes, ~0.2 C/min), so a brief low reading is a door opening or
sensor noise rather than lost soak — and a plate swap, which is exactly when
keep-warm runs, produces one. A stale history credits nothing: at that
cooling rate the chamber can cross the threshold unobserved, so the full soak
runs instead.
Three supporting changes to preheat itself:
* Cancelling or deleting a queued item now stops a preheat already running
for it. Those routes only write `status` to the database, which a dispatch
coroutine parked in `asyncio.sleep` cannot observe, so the heaters ran for
the rest of max_wait + soak — 45 minutes at the default settings — and the
printer stayed in `busy_printers`, blocking every other queued item behind
a print that was not happening. The routes now signal the scheduler
directly, and the stage sleeps in slices so it notices promptly and
abandons the dispatch, letting the existing rollback shut the heaters off.
* A chamber-heated print whose slicer metadata carries no bed temperature
(common for Orca-exported 3MFs) used to skip preheat entirely and start
with a cold chamber. It now heats the bed to `queue_keep_warm_bed_temp`.
A parsed bed temperature still wins, and a print with no chamber
requirement still skips — no bed temperature is invented for the print
itself. Preheat's bed target is transient regardless: the print's own
gcode issues its M140/M190 at start.
* Preheat records which commands it sent (bed, chamber, airduct) and unwinds
them if the dispatch aborts before the print starts — a failed upload, a
cancelled item, an exception — instead of leaving the printer heating for
a job that is not happening.
Sliced files previewed through a vendored copy of PrettyGCode in an
iframe. It drew each move as a screen-space line -- a line has no
thickness in the scene, so it cannot occlude the layer behind it, which
is why prints came out stringy and shimmered where layers crossed. Being
a separate app in a frame, it could be neither themed nor translated, and
carried its own machinery for detecting a proxy refusing the embed.
Now built on libvgcode, the renderer OrcaSlicer draws its own preview
with, vendored from three-slicer (AGPL, same as us). It takes the THREE
namespace as an argument and imports nothing, so it runs on our 0.181
rather than the 0.160 its package pins.
The parser is ours; upstream renders its own kernel's output and ships no
G-code parser at all. Two things it has to get right, both found by
checking a real plate rather than assuming:
- BambuStudio does not use the OrcaSlicer/PrusaSlicer annotations. It
writes "; FEATURE:", "; LINE_WIDTH:", "; CHANGE_LAYER" and
"; Z_HEIGHT:", not ";TYPE:", ";WIDTH:" and ";LAYER_CHANGE". Reading
only the latter showed a 52-layer print as 23,165 layers in one colour,
because with no layer marker recognised every travel Z-hop split a
layer and every segment took the fallback feature.
- It emits a tenth of its moves as G2/G3 arcs -- 706 extruding ones in a
single plate. Ignoring them punched holes through curved walls and tree
supports. Arcs with no X/Y are the helical travel lift and lay down
nothing, so they interpolate as travels.
Four colour modes: filament (default, from the AMS slots the file was
sliced with), feature, layer height, line width. Speed, fan and
temperature are deliberately absent -- upstream derives those from
settings rather than the toolpath, and guesses dressed as measurements
are worse than an honest omission. The parser now carries the data to do
them properly later.
Legend entries are switches. Hiding removes the records before the mesh
is built rather than recolouring them: the shader packs colour into a
single float with no alpha, so there is no transparent to set, and
removal is the useful behaviour anyway -- a hidden support stops
occluding what it covered.
The scene is built once and only the toolpath rebuilds. Doing otherwise
constructed a new WebGLRenderer on every render, because the buildVolume
default is an object literal and so a fresh identity each time; browsers
cap live WebGL contexts and drop the oldest, which blanked the canvas
after a few interactions.
utils/framing.ts goes with the iframe, along with six now-orphaned
strings in all 13 locales. src/lib/vendor is excluded from eslint --
acting on findings in vendored code makes it impossible to re-copy on the
next upstream release.
Model preview
-------------
The camera distance came from `maxDim * 1.8`, which accounts for neither
the camera's field of view nor the viewport's aspect ratio, so a tall
narrow panel was framed as though it were square -- the model sat in the
middle with a screenful of dead space above it. Solved from the bounding
sphere against both fields of view instead, so it fills the frame at any
panel shape. Near/far now scale to the subject rather than staying at the
0.1/10000 defaults.
Lighting was two directional lamps over 0.6 flat ambient on a Phong
material: every surface facing the same way got an identical colour,
which is what flattened models into silhouettes. Now a MeshStandard
material lit by a generated RoomEnvironment through PMREMGenerator, with
ACES tone mapping so the lit side of a saturated filament colour doesn't
clip to white and drain the hue.
Added a contact shadow. Two things would have made it silently draw
nothing: the build plate is an unlit MeshBasicMaterial and cannot receive
shadows, so the catcher is a separate ShadowMaterial plane; and three's
default directional shadow camera is a +/-5 unit box, which nothing on a
256mm bed falls inside.
The PMREM render target is disposed on unmount -- it is GPU memory the
collector cannot reclaim, and this viewer is opened and closed repeatedly
from the file manager. Device pixel ratio is capped at 2; a 3x phone
screen was quadrupling fragment load for no visible gain.
G-code preview
--------------
Switched gcode-preview from `lineWidth: 2` to `renderTubes`. A 2px
screen-space line has no thickness in the scene, so it cannot occlude the
layer behind it -- hence the stringy surface and the shimmer where layers
overlap. Tubes are built from real extrusion width and height, so the
print occludes itself.
The flag is marked experimental upstream, and the 0.42 extrusion width is
a hardcoded default that is right for a 0.4 nozzle and wrong for a 0.6.
Both are worth revisiting if this holds up in use.
Modal
-----
Removed the G-code tab. G-code has its own full-page viewer, and a
preview of a model is a different question from a preview of a print.
That left dead weight behind it: the render branch, the GcodeViewer
import, the has_gcode capability (still computed, never read), the Code2
icon, and two orphaned strings in all 13 locales. One test was repurposed
to assert the tab is absent so it cannot creep back; two others only
exercised that tab's disabled state and went with it.
The settings panel collapsed four causes into one message -- "the picked
preset's own values could not be read" -- with no indication of what to do
about it.
The overwhelmingly common cause has an obvious fix, and it isn't an edge
case: an install pulls its sidecar as SIDECAR_TAG:-latest regardless of
which Bambuddy channel it is on, so a current Bambuddy talking to a
sidecar that predates POST /profiles/resolve is the normal state, not a
misconfiguration. Those users would have seen an amber warning on every
slice with nothing pointing at the sidecar image.
resolve_profile now returns ResolvedProfile(values, reason) instead of
None for everything, the route passes the reason through, and the panel
picks its message from it:
sidecar_outdated -> name the fix: update the sidecar image
sidecar_unavailable -> the sidecar did not answer
not_configured -> no sidecar is configured
preset_unresolved -> the previous generic wording
A request that fails outright maps to sidecar_unavailable, since a
backend we cannot reach and a sidecar that will not answer are the same
thing from the dialog.
Every variant still ends with "anything you don't change still uses the
preset" -- that reassurance is the point of the notice, and it is true
whichever way the lookup failed.
Tests pin the distinction rather than just the happy path: a 404 and a
500 must produce different reasons, and each panel case asserts both that
its own message appears and that the "update the sidecar image" line does
not leak into the others.
The panel baselined every field on the option schema's compiled-in
defaults, so a preset setting a 0.42mm line width displayed 0 -- the C++
default meaning "derive from the nozzle". Every field was affected; the
Line width group just made it obvious.
Bambuddy cannot answer this itself. A standard-tier pick is only an
{inherits: ...} stub on our side, and local/cloud presets are deltas whose
remainder lives in the profile tree bundled inside the running sidecar.
The values now come from the sidecar's POST /profiles/resolve, which runs
the same resolver /slice does against the same profiles, so what the panel
shows cannot disagree with what a slice produces. Deliberately not the
local orca_profiles resolver: it walks OrcaSlicer's published tree, which
can differ from the image actually installed.
An untouched field shows the preset's value and reverting returns to it.
isModified compares against that baseline too, so fields the preset moved
off the C++ default are no longer flagged as user edits, and values nobody
typed are no longer sent. When the values can't be read -- sidecar offline
or older than the endpoint -- the panel falls back to schema defaults and
says so rather than presenting them as the preset's.
Row layout, from screenshots:
- The control column is anchored to the right edge at a fixed width. It
had been packed left after a fixed label column, leaving the values
stranded mid-container with dead space beside them.
- Units are no longer truncated to "mm o...". The cap fitted the common
"mm" but not "mm or %" or "mm/s² or %".
- The "from file" tick moved ahead of the control it qualifies; it used to
sit past the unit at the row's right edge, reading as unrelated.
Both the unit and the control keep fixed widths, and the tick's slot is
reserved on rows without one -- sizing any of them to content makes each
row's input land at a different x and the column comes out ragged.
Also fixes a field that could not be cleared: emptying a free-text input
dropped the key, so it snapped back to the baseline and retyping appended
to it ("0.42" + "0.5" = "0.420.5"). The number branch was fixed earlier;
the text branch -- coFloatOrPercent, coString, the vector types -- was
not, and the regression test used a number input so it never caught it.
Requires a sidecar built from orca-slicer-api 4b664b7 or later. Older
images 404 the endpoint, which is handled as the fallback above.
Slicing from Bambuddy meant taking a process preset as-is; any change
meant a round trip through Bambu Studio. The slice dialog now carries
OrcaSlicer's full process tree -- pages, groups, labels, tooltips,
ranges and defaults extracted from the slicer's own sources.
Enable/disable rules are evaluated from the slicer's own enable_if
expressions via a recursive-descent interpreter (no eval, CSP), with
enum comparisons validated against each option's declared values.
Anything undecidable leaves the field editable rather than greyed.
Overrides apply after the source's support config (#1881) and the
designer's carried tweaks (#2622), so an explicit choice always wins;
an untouched panel sends the same request as before.
Adds slice_engine as a separate setting from preferred_slicer -- where
slicing runs is a different axis from which binary the sidecar drives.
Only the sidecar engine is registered, so no picker renders yet.
Frontend:
- react-router/-dom 7.18.1 -> 7.18.2. The RSC-mode CSRF advisory was carried
as a documented exception in the audit gate because its only fix was the
8.3.0 major; upstream backported it, so the exemption lapsed on its own --
an entry only holds while fixAvailable.isSemVerMajor is true. The allowlist
is now empty; the machinery stays for the next one.
- dompurify 3.4.12 -> 3.4.13. Ships in the app, but the path is unreachable:
no hooks registered, IN_PLACE never used.
- js-yaml override ^4.3.0 -> ^5.2.3 (fix not backported below 5.x, so a
major) and nanoid override ^3.3.18. Both dev-only, via eslint and postcss.
eslintrc calls only load(), on the legacy .eslintrc.yml path this repo does
not use; eslint, vite build and 2861 frontend tests pass on it.
Backend:
- cryptography >=48.0.1 -> >=50.0.0, aiohttp >=3.14.0 -> >=3.14.3, pyopenssl
>=26.3.0 -> >=26.4.0. CI resolves from scratch and was already installing
the fixed releases; the floors cover the case CI does not, an existing venv
where >= is satisfied and `pip install -r` upgrades nothing. pyOpenSSL has
to move with cryptography -- each release caps it to a narrow window, so a
stale pyOpenSSL pins cryptography below its own fix line.
An H2D armed five 12-hour drying cycles inside four hours, one of them six
seconds after the previous one ended, and none ran more than a couple of
hours.
Two things combine. The firmware ends a cycle when it decides the filament
is dry rather than when the clock runs out, and reports no fault doing it --
across this printer's history the run length tracks how wet the spools were,
from nearly the full 12 hours starting at 32% down to minutes once the unit
sat at 10-13%. That part is the AMS doing its job.
The loop is ours. An AMS reports higher relative humidity while it is warm
than once it has cooled: the same unit read 10-13% cold and 15-20% through
every cycle. With the threshold at 14% the reading at the moment a cycle
ended was always still above it, so the next 30-second pass armed another
12-hour cycle. Nothing counted, nothing waited, and it only stopped when the
box finally cooled enough to read 13%.
Auto-drying now waits 30 minutes after a cycle ends before arming another on
the same unit, and gives up on a unit after two consecutive cycles that
bring the reading no lower -- logging why and sending a new notification,
on by default because it reports that Bambuddy has stopped acting. Progress
is judged against the lowest reading any cycle on that unit has ended at,
not against the threshold, so a genuinely wet spool in a humid room coming
down 40-37-35 keeps drying however far it still is from the target;
comparing against the best so far rather than the previous end stops a
sensor wobbling by one point reading as progress every other cycle. The
suspension lifts by itself once the reading falls below the threshold.
Neither guard can stop a running cycle, and a cycle Bambuddy cut short for a
print, or that the user stopped by hand, is not counted against the unit --
so a farm that dries between queue jobs is unaffected. The threshold field
now warns below 20%, and every cycle end logs the unit's temperature and
humidity, which is what made this diagnosable.
The same bundle showed unrelated tasks failing with "database is locked",
each inside a 30.000-second Discord connect timeout. Alarms are raised from
inside the loop that records sensor history, at a point where the new rows
are added but not committed; the first read in the notification path flushed
them to satisfy itself, opening a write transaction, and the provider was
then contacted over the network with that transaction still open. SQLite
allows one writer and 30 seconds outlives the 15-second busy timeout, so
every other write in that window failed. The two reads that run before a
provider is contacted no longer flush the caller's pending work, and the
connect timeout is 5 seconds rather than 30 -- the body keeps the full 30,
so image uploads on a slow uplink are unaffected. SQLite only; Postgres has
no single-writer limit.
A reporter uploaded an STL, sliced it in Bambuddy, and got a frowny icon and
"<hostname> refused to connect" when previewing the sliced file -- while the
STL's own preview worked. That is Chrome's ERR_BLOCKED_BY_RESPONSE page, drawn
inside our layout shell, and the split between the two previews is where the
cause is: an STL or source 3MF renders in the page, a sliced file opens the
embedded G-code viewer, which is the only thing in Bambuddy that frames a
Bambuddy page (FileManagerPage.tsx:2472, GCodeViewerPage.tsx:47).
Our headers permit that frame -- frame-ancestors 'self' plus SAMEORIGIN on
everything under /gcode-viewer (main.py:7709) -- and the frame is same-origin,
so a refusal means a stricter header was added after we replied: a reverse
proxy, a security add-on, an auth gateway. None of which the user could see.
The browser drew its own page and nothing said what was refused, by whom, or
that the viewer opens perfectly well in a tab.
The frame cannot report this itself. A frame blocked by X-Frame-Options or
frame-ancestors still fires onLoad -- the browser commits an error document --
so there is no failure to catch. The page now asks for the same URL directly:
same-origin, so every response header is readable, and it goes through whatever
proxy the browser reaches Bambuddy by.
findFramingRefusal reads the verdict the way a browser does. frame-ancestors
wins outright when present, because CSP requires X-Frame-Options to be ignored
in that case -- reading both would blame a proxy-added DENY the browser never
consulted. Multiple CSP headers are intersected and fetch joins them into one
comma-separated string, so every frame-ancestors occurrence has to permit us,
not just the first; that is the shape a proxy appending its own policy to ours
actually takes. Failing that, a legacy header that is anything other than a
single SAMEORIGIN refuses us, including the conflicting "SAMEORIGIN, DENY" that
appears when a second copy is appended.
On refusal the frame is replaced with the header named verbatim, so an operator
can go and find the rule in their proxy config, and a link that opens the viewer
in its own tab -- a top-level page, which no framing header applies to. A
non-200 is reported the same way rather than as raw {"detail":"Not Found"}
inside the frame, which the startup-time warning at main.py:8120 already calls
out as easy to miss. A probe that cannot reach a verdict changes nothing: the
iframe stays, because guessing at a cause we cannot see is worse than the
browser's own page.
The working case is unaffected -- the iframe renders immediately as before and
the probe only ever replaces it.
Hovering most of Bambuddy gave an arrow rather than a hand. Not everywhere,
which is what made it read as sloppiness rather than a bug: the update pill was
inert while the buttons beside it were fine, a bed or nozzle tile responded but
the history-graph button in its corner did not, and dropdowns went either way
with no pattern behind it.
The pattern was there. Tailwind v3's Preflight set `button { cursor: pointer }`.
v4 dropped it to match the browser default, which for a button is `default`.
Bambuddy has been on v4 since the frontend was built, and `src/index.css` never
had a base layer restoring it, so a button only looked clickable where someone
had written `cursor-pointer` by hand. 15 of 934 had. 0 of 149 selects, and 19
of 130 checkbox/radio inputs. The 233 ad-hoc `cursor-pointer` usages are why it
looked arbitrary instead of uniformly broken.
One `@layer base` rule now covers button, select, checkbox, radio, summary and
[role=button]. base sits below utilities, so `cursor-not-allowed` and the
`disabled:cursor-*` variants still win; the `:not(:disabled)` guard catches the
disabled controls that carry no such utility. Verified against the built bundle
rather than the source -- the rule lands inside @layer base, and
`.cursor-not-allowed` is emitted after it.
Click-outside backdrops are deliberately excluded. 90 of the 96 remaining
onClick divs are `fixed inset-0` overlays; a full-screen sheet advertising
itself as a button is worse than one that says nothing. Of the rest, 50 are
stopPropagation wrappers and 3 are the temperature tiles, which already set the
cursor through `statusControlClass` -- which is exactly why those tiles worked
while the button nested inside them did not. That left two real ones: Card, now
conditional on an onClick actually being passed, and the queue card, whose
existing `sm:cursor-default` kept the desktop intent.
Separately, from the same report. FilamentHoverCard draws the slot menu twice,
and the two paths had drifted into opposite orders: Configure above Assign Spool
on an empty slot, the reverse on a filled one, so the menu reshuffled itself
depending on whether the slot held filament. Both now lead with the spool
action. Tests assert the order on each path, so one can no longer move without
the other -- checked by reinstating the old order and confirming the empty-slot
test fails.
Those buttons also used justify-center, which centred each label independently
and left the icons in a ragged column; they are justify-start now. Their hover
was a 10% opacity step that was very hard to see, now 20%. And the favourites
star previews yellow on hover, suppressed when the user lacks archives:update.
A reporter tried to connect to Bambu Cloud and got "We need you to confirm you
are not a robot" as an error toast, with no CAPTCHA anywhere to answer and
nothing to click. That sentence is Bambu's, not ours. Their anti-abuse layer had
flagged the network and was answering the sign-in with HTTP 418 and a challenge
body: {"captchaId": "...", "error": "We need you to confirm you are not a
robot"}.
Bambuddy had no idea what that was. The reply is well-formed JSON, so
_detect_cloudflare_challenge -- which triggers on an unparseable body, CF
markers, 403+cf-mitigated or 503+cf-ray -- never fired on it, and login_request
fell through to its generic error path, which lifts data["message"] or
data["error"] out and hands it to the UI verbatim. The user was left to conclude
their password was wrong or that Bambuddy was broken. Four sign-in attempts
inside eighteen seconds appear in their log, each one more evidence for the
thing that had flagged them.
is_captcha_challenge matches on the 418 status plus a challenge marker in the
body -- captchaId is the reliable one, the wording is matched too because Bambu
has shipped it under more than one phrasing. A bare 418 with no marker is
has shipped it under more than one phrasing. A bare 418 with no marker is
deliberately NOT reported as a CAPTCHA: telling someone to solve a challenge
that was never offered is the exact confusion this issue is about.
login_request, verify_code and verify_totp now return reason="captcha" with an
explanation covering the three things the reporter had no way to find out: the
credentials are not the problem, the block is keyed to the public IP address
rather than the account, and it clears by itself within a few hours.
Sign-in requests are then held back for 300s so Bambuddy stops deepening the
block. Keyed per origin, not per service: TOTP verification posts to
bambulab.com while everything else posts to api.bambulab.com, and a challenge
seen on one must not strand somebody halfway through a two-factor sign-in on the
other. Entries expire on read, so the map cannot grow past one per region. The
token endpoint is deliberately left ungated -- it is the way out.
The UI shows a persistent panel rather than a toast. A toast names a problem the
user cannot act on and then vanishes; this one stays put and carries a one-click
route to "Use access token instead", which is the only thing that works while
the challenge lasts, since that path does not touch the challenged endpoint.
MakerWorld meets the same challenge from the same edge and now shares the
detection. It used to require the literal word "robot" in the error text and
reported any other wording as an unexplained block.
The System Health scanner gets a bambu-cloud-captcha signature. The reporter's
bundle came back with zero findings while their log was full of the failure.
Its advice for a failed FTPS handshake was corrected at the same time: it still
blamed firewalls and outdated firmware, which the #2780 investigation ruled out
last release -- it is the printer's own file service wedging, and the fix is to
restart the printer. The wiki said so already; the health panel did not.
Two printers went on printing while every archive they produced held nothing
but a filename. Bambuddy opened port 990, the printer accepted the connection
and answered with something that was not TLS, and connect() logged a warning
and returned False -- indistinguishable, to every caller, from "the file is
not at this path". So the 3MF lookup walked all six filename variants across
five directories with four retries each, the cover endpoint ran its own
sixteen-path sweep, and the timelapse scan added four more, all against a
sixteen-path sweep, and the timelapse scan added four more, all against a
printer that could not have answered any of them. One reporter's log carried
1813 identical handshake failures, another's 3511.
The evidence says this is the printer's own file service getting stuck, not a
model, firmware or TLS-configuration problem. In #2780's bundle the same two
printers ran clean from 22 July to 4 August and failed again from the 5th; a
second bundle shows an X2D serving files for five days, flipping on 19 July,
then failing every connection for eight days with zero successes. The same
models and firmware appear in roughly twenty other bundles with no occurrences
at all. Both bundles show it happening with cap_tls_v1_2 in effect -- the X2D
and H2C entries in ftp_profiles were added on analogy with P2S to fix exactly
this symptom, and the reporter's own debug line proves they do not.
An ssl.SSLError from connect() now opens a five-minute cool-off for that
printer. Subsequent connects return False without touching the network, so a
wedged printer is contacted twice an hour instead of hundreds of times a
minute, and the single warning that is logged names the remedy. The cool-off
is dropped on expiry rather than kept, so the map holds one key per currently
wedged printer. ftps_handshake_blocked() lets the sweeps stop: the 3MF lookup
abandons the remaining paths and skips the directory-walk fallback, the cover
endpoint returns 503 naming the file service instead of a 404 that reads as
"this print has no thumbnail", and the timelapse scan separates 503 (cannot
reach the printer) from 404 (no timelapse directory) -- one 500 used to cover
both, which is what the reporter hit when reproducing.
The Connection Diagnostic completed a bare TCP connect to 990, which is why it
reported the port green throughout: the port is open, it is what is behind it
that is broken. It now completes a real implicit-TLS handshake using the
model's own ftp_profiles cap, so a pass means the FTP client would also get
through. An open port that cannot negotiate reports warn with reason no_tls,
selecting a new message in all 13 locales that points at a printer restart
rather than at the firewall. No login is attempted, so this stays valid in the
pre-save Add Printer flow.
The cool-off tests run against a real socket that accepts on 990 and replies
with a plaintext FTP banner, reproducing WRONG_VERSION_NUMBER rather than
mocking ssl. The autouse fixture clearing _mode_cache now clears the cool-off
map too -- every test here talks to 127.0.0.1, so one left behind would make
the next test's connect() a no-op.
ForgejoBackend.test_connection asked GET /user who the token belonged to
before asking whether the token could reach the repository, and treated a 403
there as fatal. A Forgejo v15 repository-scoped token may only carry
read/write on issues and repositories, so it 403s on /user -- and was rejected
despite reaching its own repository fine, which is all a backup needs: the push
path uses the Contents API and restore reads commits, trees and blobs, all
under /repos/{owner}/{repo}. That /user call was the only one in the whole
provider layer.
The probe stays, because a 401 from it is genuinely conclusive and names a bad
token before the repo call has to guess -- Forgejo v15+ hides a private repo
behind 404 rather than 403, so the repo call cannot always tell those apart.
Every other status now falls through to the repo check.
Two additions keep the messages as sharp as before: the repo call's own 401 is
mapped to "Invalid access token" instead of a generic API error, and the 404
names write:repository and the scoped-to-another-repository case, mentioning a
possibly-invalid token only when /user did not confirm the identity.
The token hint under the field was one shared string reading "fine-grained
token with Contents read/write" -- GitHub's advice, shown to Gitea, Forgejo and
GitLab users too. It is now per provider via PROVIDER_TOKEN_HINT_I18N_KEY,
following the existing repo-URL placeholder map, translated in all 13 locales.
Tests pin the repository-scoped token connecting, a transient /user status not
blocking the repo call, both 404 wordings, and the repo-call 401; a frontend
test switches providers and asserts the hint follows.
Projects were flat. The parent_id column and the sub-project list existed
but nothing could set a parent outside the API, and a master project's
stats only ever covered its own prints.
The project dialog gets a parent picker, and a project with sub-projects
gets a second card covering the whole tree -- jobs, parts, time, filament,
cost, and progress against every target in the tree added together. That
card is separate from the project's own stats, which keep their existing
meaning; widening them would have restated the figures of anyone who had
already nested projects over the API. Each listed sub-project carries its
own branch's roll-up, so the rows add up to the card above them.
On the Projects page a sub-project is drawn inside its parent's group
rather than as another card in the grid -- two cards columns apart cannot
show that they belong together, whatever the caption says. A sub-project
whose parent the status filter has hidden stays put and names its parent
instead.
compute_project_stats now goes through the same grouped aggregation as the
roll-up rather than its own copy of the SQL, since the two must agree.
Three things the interface made reachable:
- PATCH refused only a project as its own direct parent, so A -> B -> A
was two calls away. A cycle has no root to roll up to, and the walk
keeps its seen-set for databases that already contain one.
- A sub-project's percentage was completed quantities against the plate
target, disagreeing with the page it linked to.
- Deleting a mid-tree project orphaned its children at top level; they
now move up to its own parent.
The service reports what landed on a part-way failure -- categories commit as
they finish, so results names the ones on disk -- and the modal gated the
whole result panel on success, so it showed the failure message and dropped
them.
The cache invalidation was inside that same branch, which is the half that
mattered: a run that committed the settings category and then failed left the
app rendering pre-restore settings, with no reload and no re-read, which is
the failure the modal's own reload-on-close exists to prevent.
Gate on what was written instead. A refusal that never reached a category
still carries an empty results and still keeps the form, so the mutex and
backup-in-flight cases are unchanged. A partial does not read as a success:
the tick becomes a warning and a line says the listed categories are the ones
on disk.

fix(backup): keep the local owner when the backup names one we cannot resolve (#2656)
An owner the backup names but this instance has no user for was written as
NULL, and overwrite is a blanket setattr -- so restoring over a local archive
that had a perfectly good owner took it away, which is the 404-for-its-own-
owner failure this column is carried across to fix. Resolving by username
widened the trigger from a stale id to any user renamed since the backup.
It is the same state as an absent key: the backup has not told us who owns
this. So it takes the same action -- the column is not written at all.
Overwrite keeps the local owner, insert lands ownerless with the note, and an
explicit null still writes, so overwrite still means "match the backup".
The notes move to the insert path with it. On overwrite nothing was taken
away, so there is nothing to warn about, which is the rule the absent-key
case already follows.
The drying popover prefilled its material from the loaded spool without
checking the preset table had that material. An AMS-HT holding Support for
PLA/PETG (tray_type PLA-S) fell back to PLA's temperature but kept PLA-S as
the material, and the dropdown displays its first option when handed a value
outside its list -- so it read PLA while PLA-S was sent. Same gap for every
composite: PETG-CF prefilled at PLA's 45C.
Resolve the tray_type to a key the table has before setting either value.
Support materials and composites resolve to their base, nylon is aliased
under its several spellings, and anything unrecognised falls back to PLA --
the coolest row, so an unknown material under-dries rather than deforming a
PLA spool.
Also record request-topic messages in the MQTT debug log. That topic carries
every command a printer is given, including Bambu Studio's, and returned
before the logging block -- so a capture could show only what the printer
said, never what it was told.
Two ways the K-profile and spool categories broke the
restored + skipped + failed == item_count invariant the settings count
holds:
* The spools preview counted only the spools and put the usage records
in the detail, but _restore_spool_usage increments the same tally, so
any backup with usage history reported a total larger than the number
the user was shown. The preview now counts both and the detail breaks
the total down instead of adding to it.
* A K-profile entry that is not a dict was dropped silently on the
connected path. _kprofile_profile_count includes it, so the offline,
printer-missing and step-failed paths all account for it; only the one
path that talks to a printer let it leave the tally. It now counts
failed.
created_by_id is only meaningful on the instance that wrote it. Restoring
onto a rebuilt instance - this feature's main use case - renumbers the
users table, so a live id can land on a different person and hand one
user's print history to another under archives:read_own. The id path
cannot even detect that: archivesOwnerCleared fires only for an id that
is absent, so a valid-but-wrong id produced no note at all.
The collector now records created_by_username alongside the id, and the
restore prefers it. username is unique on users, so a match is the same
person; the one case it cannot resolve - a user renamed since the backup
- falls through to ownerless with a note rather than guessing from the
id. The id stays as the fallback for backups taken before this change.
Removing the requestAnimationFrame wrapper fixed the total stall but left the
100ms coalescing timer in the path, and a hidden page's timers are clamped to
once a second at best -- once a minute past five minutes hidden. The reporter
still saw a tab title at 2% beside a page at 40%.
The coalescing guards against a render cascade, which a hidden tab cannot
have, so it is skipped there and kept while visible.
The existing hidden-tab tests advanced fake timers, which simulates the timer
the browser was throttling; the new one never advances the clock.
Binds binary_sensor and reading-carrying sensor entities to a printer and
renders their state on its card, worded by Home Assistant's device_class.
Optional per-sensor alert condition drives a notification on the transition
into the alert state and an opt-in interlock that holds queued prints while
alerting -- a hold with a readable waiting_reason, never a failure, and only
ever on a sensor that was read successfully.
Sensors get their own table rather than a wider entity pattern on SmartPlug:
get_smart_plug_by_printer would otherwise hand the card's power button a door
contact to switch.
The hold is passed to the model matcher directly rather than merged into
busy_printers: _check_auto_drying reads that set as "is currently printing"
and would put an idle-but-held printer down the mid-print drying path.
The notification_providers migration spells its default FALSE, not 0 --
Postgres rejects an integer default for a boolean and _safe_execute swallows
the error.
The desktop handoff accepted library:read alongside read_all/read_own, on
the reasoning that default groups do not carry it and requiring it would
lock out Operators and Viewers. The permission grants nothing in that
position: the slicer-token endpoint gates on
require_ownership_permission(LIBRARY_READ_ALL, LIBRARY_READ_OWN), and
neither that dependency nor User.has_permission expands the legacy name,
so a group holding only library:read gets a 403 there. It cannot reach
the File Manager to try, either - GET /library/folders gates on the same
pair - and the library:read -> library:read_own migration in
core/database.py runs only over the groups named in DEFAULT_GROUPS, so a
custom role that still carries it stays stuck rather than being upgraded.
custom role that still carries it stays stuck rather than being upgraded.
Accepting it only enabled a menu item the server refuses, and the failure
is indistinguishable from "no slicer installed" once the catch hands the
unauthenticated URL over. Removed, with the comment recording the reason
so the next reader does not re-add it, and a test that pins it.
---
refactor(slicer): share one sliceable-file-type rule (#2725)
The File Manager and the 3D preview decide the same thing about the same
file and each held its own list of extensions - which is how they came to
disagree, offering a desktop handoff for an STL whose own preview showed
"Open in Slicer" greyed out. Making the two lists identical fixed the
symptom and left the drift, so SLICEABLE_FILE_TYPES now lives in
utils/slicer.ts with isSliceableFileType for a stored file_type and
isSliceableFilename for a name.
The filename form still rules out the compound extensions explicitly,
since .gcode.3mf ends with .3mf; the type form does not need to, because
classify_file_type stores that one whole.
Both test files mocked the whole slicer module, which would have replaced
the new predicates with undefined - switched to importOriginal so only
openInSlicer is stubbed. That is the better shape regardless: the tests
now exercise the rule the component runs instead of a copy declared
beside them.
Carries the rebuilt bundle. The CSS hash moves with it - the split button
introduces Tailwind classes the previous build had no reason to emit.
The follow-up to the same report: a second AMS 2 Pro, no aux power,
loaded entirely with PLA and drying at the 45C the reporter picked,
showed 45C and then switched to 55C.
Bambu never echoes back a cycle's filament or temperature, so both come
from the target cached when the command went out, and the fallback for
a missing cache reads the loaded trays. The first pass narrowed that
fallback to units whose spools agree on a filament, which fixed the
mixed-unit case in the original report but left the uniform case
answering with the spools' RFID-recommended drying_temp -- 55C here.
Agreement across slots is evidence of what is being dried, because the
dryer heats all of them. It is no evidence of the temperature, which is
picked freely in the popover, so the recommendation was never more than
a guess wearing the same confident "PLA @ 55C" as a known target.
uniform_tray_drying_hint therefore becomes uniform_tray_filament_hint
and returns the filament alone. The badge names a temperature only when
we sent it, and otherwise shows the filament and the countdown.
Both status builders also stopped filling the two fields independently.
Entering the fallback when either was missing let a cached filament pair
with a guessed temperature and render as though both were known; the
temperature now simply has no fallback to reach.
The badge required both fields before rendering anything, so dropping
the temperature would have blanked it rather than shortening it -- the
frontend now renders each on its own terms. No new translation key: the
filament type is a passthrough.
This changes what is shown when the cached target is missing, not why
it goes missing. If the reporter was on the fixed build, the falling-
edge gate is still letting a zero through on an unpowered unit, which
needs a log covering the start of the cycle.
5.0.8's maxLength cap was applied in combine(), where output is merged, but
not to the two arrays built before it runs: comma alternatives each got their
own full allowance and were concatenated with no running total, and padded
sequences never consulted maxLength at all. So a ~25 KB pattern still OOMs the
process -- fatally, past the reach of try/catch -- and a ~400 KB one blocks the
event loop for over two minutes. 5.0.9 bounds both as they are built.
Dev-only and transitive here: it reaches us as eslint -> minimatch@5 ->
brace-expansion, the only input it sees is our own lint globs, and it is not in
the shipped bundle. The ci.yml audit gate runs --omit=dev, so this never would
have failed CI; it surfaced through Dependabot.
The overrides floor is bumped alongside the lockfile so a clean install can't
resolve back to the vulnerable 5.0.8.
