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.
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.
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.
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 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.
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.
Switching a card from M to XL made it wider, enlarged the printer name
and the thumbnail, and left everything else where it was. The AMS slot
labels, temperatures, filament names, status text and every small button
stayed pinned between 8 and 11 pixels -- under the smallest size used
anywhere else in the app -- so a full-width card carried the same tiny
text as the compact one. Browser zoom does not answer this: it enlarges
the whole page and so preserves the very disparity being reported.
The card root now carries ten custom properties derived from cardSize,
and the 200 fixed sizes in its subtree reference them: text-[10px]
becomes text-[length:var(--pc-t10,10px)], w-3 h-3 becomes
w-[var(--pc-i3,0.75rem)]. L draws the body 20% larger and XL 40%,
icons included, so the controls grow with the text instead of staying
fiddly to hit.
Custom properties rather than an em-based root font-size. Setting
font-size on the card would silently reshape any text that declares no
size of its own, and would break for portalled content. Each converted
class names its old fixed value as the fallback, so anything rendering
outside a card root is untouched -- which is what leaves the portalled
temperature popover exactly as it is. Its four sites stay fixed on
purpose, as does the page chrome; the conversion was scoped from the
function declarations rather than line numbers, and afterwards only
those four intended sites still hold a literal px value.
S and M stay at 1.0. S is the dense fleet view where density is the
point and M is the default, so an existing install looks identical until
the user reaches for a size that is already asking for more room -- the
same control the request asked this to follow.
The AMS-HT card needed separate work, because its temperature and
humidity readings sit beside the slot rather than under it. That single
slot was the only growable item on its row, so it took every spare pixel
and pushed the readings hard against the card's edge; it is now capped
at roughly two ordinary slots, which keeps them clear at any card width.
The card itself is capped at one full AMS card's width, so a unit that
wraps onto a line of its own no longer stretches that slot across the
whole card.
The AMS slot minimums are deliberately NOT scaled. Raising them was
tried and reverted: those cards already grow to fill their row, so
3.5rem is a floor they sit well above, and raising it only cost a unit
its place on the row -- which is what pushed the AMS-HT onto a line by
itself and exposed the stretching above. A test pins them at 3.5rem at
XL so this reads as a decision rather than a missed spot.

w-[var(--pc-i3,0.75rem)]. L draws the body 20% larger and XL 40%,
icons included, so the controls grow with the text instead of staying
fiddly to hit.
Custom properties rather than an em-based root font-size. Setting
font-size on the card would silently reshape any text that declares no
size of its own, and would break for portalled content. Each converted
class names its old fixed value as the fallback, so anything rendering
outside a card root is untouched -- which is what leaves the portalled
temperature popover exactly as it is. Its four sites stay fixed on
purpose, as does the page chrome; the conversion was scoped from the
function declarations rather than line numbers, and afterwards only
those four intended sites still hold a literal px value.
S and M stay at 1.0. S is the dense fleet view where density is the
point and M is the default, so an existing install looks identical until
the user reaches for a size that is already asking for more room -- the
same control the request asked this to follow.
Wiki notes the scaling in the card-size table and why it differs from
browser zoom. Tests pin the variable values at every size, including
that S and M still emit the pre-change sizes.
An external spool holder that never gets used still takes a full card's
width in the Filaments row, next to the AMS units that are actually in
use. An eye icon at the right-hand end of that row's header now hides
it, and clicking it again brings it back -- the affordance stays in
place rather than moving to a settings page, so the choice is
discoverable and reversible where it applies.
Per printer rather than global. A global flag would suit a toolbar
button, but an icon on the card that silently rearranged every other
card would surprise; it is keyed by printer id in one localStorage
entry, the same shape as printerCollapsedSections, and sits alongside
the other browser-local printer-page view preferences.
The toggle is offered only when the printer has at least one AMS. On a
machine with no AMS the external spool is the entire filament section,
so hiding it would leave an empty row with no control to undo it. The
icon and the hide condition read the same canHideExternalSpool, so a
preference stored before an AMS was unplugged cannot blank the row
either -- the spool reappears instead.
The store lives in a new utils/printerCardPrefs.ts rather than in the
9,157-line page. It re-reads before writing so two cards toggled in one
session cannot clobber each other's entry, deletes the key instead of
storing false, and treats a malformed or unavailable localStorage as
"nothing hidden" so a private-mode browser cannot throw out of a render.
The overlay at /overlay/{printer} draws live print data over a
full-screen camera view for OBS, a wall display or any browser source.
It has been tunable since it shipped -- which fields, what size, what
frame rate -- but only through query parameters documented in the wiki,
and temperatures were not among the fields on offer. The request asked
for temperatures first and for the field set to be selectable in the web
UI; this addresses both.
Nozzle, bed and chamber readings join the list. The target is drawn only
while the heater is still climbing, so a settled hotend reads "220°C"
for the rest of the print instead of the noisier "220 / 220°C" -- 219.6
against a target of 220 rounds to the same number, and repeating it says
nothing. Both nozzles appear on a dual-nozzle machine. They are drawn
whether or not a print is running, because a preheating printer is
exactly when they are worth watching, and each reading appears only when
the printer genuinely reports one: chamber temperature stays absent on
P1 and A1 models, which publish a chamber_temper with no sensor behind
it, so the overlay never puts a measurement on screen that does not
exist. Labels reuse the heater chart's strings rather than inventing a
second vocabulary for the same three things.
The feed sends an allow-list rather than the temperatures dict. That
dict doubles as the MQTT client's working memory -- derived heater flags
and private target-set timestamps live alongside the readings -- and an
overlay token is a narrower grant than a login, so it gets exactly what
the overlay draws and does not pick up fields as the dict grows. The
same chamber-sensor gate the full status payload already applies is
applied here. The integration test that asserts the payload's exact key
set, which exists to catch that surface widening silently, is updated
deliberately.
Temperatures are not in the default field set, so an overlay URL already
pasted into a scene renders identically after upgrading.
Settings -> API Keys -> Streaming Overlay now builds the URL: printer,
field checkboxes, size, frame rate, camera toggle, an optional token,
and a copy button. It persists nothing and calls nothing new -- the URL
is the configuration, which keeps a scene reproducible by copy-paste and
lets two displays show different fields off one token. Fields are
emitted in the overlay's own top-to-bottom order rather than click
order, and parameters left at their default are omitted, so the same
selection always produces the same URL. The preview alongside it stays
off until asked for: an always-live iframe would hold a subscriber on
the printer's single camera connection for as long as the settings tab
stayed open.
The preview needed one narrow security-header change. Every SPA route
sent frame-ancestors 'none', which is stricter than the SAMEORIGIN in
X-Frame-Options beside it and refuses even a same-origin frame, so the
preview showed Firefox's "another site has embedded it" page instead of
the overlay. The overlay path now sends 'self', mirroring /gcode-viewer,
which admits a framer only on this origin -- Bambuddy's own UI. Every
other path keeps 'none', and embedding the overlay from another host
still requires TRUSTED_FRAME_ORIGINS.
Printing a multi-plate file in different quantities per plate meant
queueing each plate separately and tracking the counts by hand: one
shared Quantity field cannot say "plate 1 once, plate 2 twice, plate 3
three times". Each selected plate now carries its own quantity, and the
submission becomes an order on a new Batches tab.
The point is the distinction the old flat batch could not express.
print_batch_plates stores how many runs of each plate were wanted,
separately from what was queued, so a run that fails, is cancelled or is
skipped does not satisfy a target -- the order goes on saying it owes a
print instead of quietly under-delivering. Queue remaining re-queues
exactly what is missing, for the whole order or one plate, by cloning
the most recent item for that plate: that inherits the printer or model
target, AMS mapping, filament overrides and print options along with the
validation they already passed, rather than re-serialising twenty fields
through a template that would drift from the model the first time
someone adds a column. Clones append to the end of the relevant
printer's queue and take the same advisory lock the add-to-queue route
does; positions are per-printer sequences, not global.
Cost is measured, not estimated. print_log_entries gains queue_item_id,
set where the queue item is already in scope, so each run's material and
energy are attributed through the item that produced them -- an
unrelated reprint of the same archive never lands in an order's total,
and a multi-plate order gets each plate's own cost rather than the whole
file's via the plate-scoped estimate from #2614. Before any run has
completed there is no honest figure, so cost reads as unknown instead of
a fabricated 0.00.
The Batches tab wires up GET /queue/batches, which has been unreferenced
since the batch MVP shipped, along with six locale keys that were
translated and never used. It is a separate tab because an order
outlives the queue that produced it: once its runs finish they leave the
active queue, so Queue and History each hold half the picture.
completed was not a reachable status before now, so every batch created
since April is still marked active however long ago its last print
finished -- 73 of them on the development install. A startup pass closes
out the finished ones: those whose runs all completed become completed,
and groupings whose items were all cancelled become cancelled, which is
what they are. Not applied to orders, which state their intent
independently of their runs and still owe the work. Only batches with
nothing queued or printing are considered, and repeating the pass also
catches an order whose last run landed while the process was down.
Batches with neither items nor targets are no longer listed at all --
empty shells left when a grouping's items went with their source
archive.
Dispatch applies the same source-file gates as POST /queue/. It creates
queue items, so without them it would be a weaker door to the same
outcome; the archive and library-file checks move into shared helpers
so a third route cannot drift from them.
The floating disc is pinned bottom-right, which is where most controls
live — it covered ~83% of the Profiles scroll-to-top button at the same
z-index, and being viewport-fixed it also sits on card action buttons
that scroll under it. Below the sidebar-compact breakpoint the trigger
moves into the top bar; at 1144px and up nothing changes.
Not a hide switch: the bubble is the only entry to the report form, and
that form runs the printer diagnostic, the log scan and the debug
capture. Hiding it yields reports with nothing attached.
The panel stays at the Layout root — the header is a fixed z-40
stacking context and would bury a nested z-50 panel under every modal.
Also fixes the panel hanging 16px off-screen on phones: w-full resolves
against the viewport, so right-4 pushed its left edge negative.
The Color column was missing from the page's sort-extractor map, so its
header ignored clicks. Sorts by family first — rainbow, then browns,
then neutrals light to dark — with the hue sort running inside each.
The issue asked for a straight hue/saturation/lightness sort. Measured
against a real 30-spool inventory that puts Titan Gray (hue 210, sat
0.04) among the blues and a warm grey next to the reds, and splits the
oranges around brown. Neutrals order by lightness because their hue is
noise.
Families come from the classifier that already names colours missing
from the catalog, so the Color and Color Name columns cannot disagree.
The printed command only works from the directory holding the compose
file, which is the thing the user came to the page not knowing. Adds a
copy button, a saved Compose directory setting, BAMBUDDY_COMPOSE_DIR,
and best-effort detection from a bind mount's host path.
Compose records the directory on every container it creates, but reading
that label needs the Docker socket mounted in — root-equivalent access
for a convenience string. The mountinfo guess is a prefill only: its root
field is relative to the mounted device, so a compose dir on its own
mount loses that prefix, and nothing in the container can detect it.
The field is restricted to path characters. It is the one setting whose
purpose is to be pasted into a root shell, so "/opt/bambuddy; rm -rf /"
would otherwise render as a plausible update command.
The list and update endpoints serialised field by field and never named
cost / energy_kwh / energy_cost, so values Bambuddy had been recording
all along went out as nulls. Both now validate from the ORM row, which
removes the chance to omit a field rather than patching the three that
were missing.
Adds a Filament Used column plus a Columns picker for Cost, Energy,
Energy Cost and Finished, persisted per browser.
Also fixes the log view being unreachable with zero archives: the empty
state ran before the view check, hiding a log that outlives the archives
it refers to.
---
Sort the Print Log by any column (#2636)
Adds sort_by / sort_dir to the print-log endpoint, driven by clickable
column headers. Server-side because paging is: ordering the rows the
client holds would sort one page rather than the log.
Empty values are held last in both directions — Postgres sorts NULLs
high and SQLite low, so the same click would otherwise open on blanks
on one backend and values on the other. id DESC breaks ties so paging
through a low-cardinality sort can't repeat or skip a row.
The edit dialog offered a printer picker and target-model dropdown for
an item with alternatives. Saving left a row with variants AND a
printer_id, and the scheduler's fixed-printer branch wins that race, so
it dispatched a row whose library_file_id is still null and failed in
the upload. PATCH now refuses printer/model changes on such an item —
comparing against the current value, since the dialog re-sends
target_model unchanged — and the route eager-loads variants, without
which the guard could not see them and every PATCH response dropped the
alternatives from its payload.
Names come from a shared helper now. A cross-model item holds neither
archive_id nor library_file_id until dispatch, so five separate inlined
fallbacks all rendered "File #null"; they now read "x1c.gcode.3mf +1
more".
The queue also grouped these under "Any H2D" — the first candidate
mirrored onto the row — filing a job under a printer it might never run
on. It groups as "Any H2D / X1C", matching the row beneath it.
Selecting several sliced files and pressing Print now creates one queue
item carrying all of them, instead of hiding the Print button the moment
a second file is selected. The printer picker is replaced by the ordered
candidate list, since choosing these files is already the answer to
"which printer" and the only question left is which is preferred.
Per-candidate configuration is the plate only. Model-based assignment
sends no AMS mapping — the printer is unknown until dispatch, where the
scheduler derives it — so a per-candidate mapping editor would collect
choices it then discards. Filament overrides stay shared: "this job
needs PETG" holds for every slice of the same job.
Adds Group as versions for durable grouping, a versions badge counting
the whole group rather than the rows on screen, and a queue card label
naming every model a pending item is waiting on.
Every field that takes a chamber target stopped at 60: the per-filament
chamber map and per-print override in Preheat & Heat Soak, the chamber
quick-select presets, and the printer-card chamber control. 60 is the
X1E's ceiling and the X1E was the only heated-chamber model when that
limit was written; the H2 series and X2D heat to 65, so the top of their
range was unreachable.
The ceiling now lives in one constant per side (MAX_CHAMBER_TEMP_C in
backend/app/utils/printer_models.py and frontend/src/utils/printer.ts)
rather than as a literal at each call site. X1E firmware clamps a higher
request to its own maximum, so a shared ceiling is safe.
Also fixes a live bug at PrintersPage.tsx:7985: parsePresetTriple was
bounded to 60 there, and it rejects the whole triple on any out-of-range
entry, so a saved 65 preset would have silently reverted the printer
card to the defaults while Settings still showed 65.
The scheduler only writes waiting_reason on the model-based assignment
path, so a job pinned to a specific printer sits behind a running print
with no marker at all. Every such job rendered an identical "starts now"
ETA that was wrong by the length of everything ahead of it.
Decide eligibility on the page instead: an item gets an ETA only when its
printer is idle and it is the item the scheduler would dispatch next,
following the same ordering the scheduler uses. Staged and future-
scheduled items do not block the item behind them, matching the
scheduler, and items conditional on a previous print are excluded.
The value also froze at first render, since react-query's structural
sharing keeps the queue reference stable and nothing re-rendered the row.
formatETA now accepts a base instant and the page drives it from a 30s
clock shared by every visible row.
Retire the borrowed printers.estimatedCompletion tooltip for a queue key
that says what the number means, translated into all 13 locales.
While the Settings page was mounted it held its own copy of every
setting and synced it from the server exactly once, on first load
(:887-900). A debounced effect then diffed the live ['settings']
cache against that copy and PUT all 77 keys it manages on any
difference, with no way to tell a user edit from a value that had
changed on the server. Anything written server-side while the page
sat open was silently reverted ~500ms later (#2716, reporter
@jmoore-skild).
No interaction was needed to trigger it. The query inherits a 60s
staleTime and react-query's default refetchOnWindowFocus, and ~30
other observers share the key, so a window refocus or a refetch from
any of them moved the cache and the page wrote its page-load snapshot
back over all 77 keys -- showing "Settings saved" while doing it.
The page now tracks the last server snapshot it reconciled with. A
field still equal to that baseline has not been touched since, so a
newer server value is adopted; a field the user has edited keeps
their value and is saved over the top, so the newer of the two writes
wins either way. Typing into a text field while a refetch lands stays
safe, which is what the previous behaviour was protecting -- an
in-progress edit is by definition different from the baseline.
The baseline is seeded from the raw server row rather than from the
copy the page patches a browser-detected external_url into, so that
detection still reads as a local change and is still persisted.
The payload builder and the comparison key lists are unchanged. The
diff simply measures against the baseline instead of the live cache,
so no field can silently stop saving.
Removing the adoption step was verified to reintroduce the revert,
and removing the post-save baseline advance to reintroduce a resend
loop; both are covered by frontend tests asserting on the request
bodies rather than on rendered values.
Round-3 review of the "Save AMS mapping" PR.
The queue item's ams_mapping was set unconditionally, on the reasoning that
honouring the slicer's own pick is a correctness fix rather than a feature.
It is both. Storing a resolved mapping makes _ensure_ams_mapping return
early, so _compute_ams_mapping_for_printer never runs — and that function is
where prefer_lowest_filament lives, along with the AMS-filament-backup gate
that qualifies it (#1766), the inventory-remain overrides, and the per-slot
force-colour overrides. Every existing queue-mode VP pointed at a printer
would have quietly lost all of it on upgrade, without a setting to turn it
back on.
So save_ams_mapping now gates the queue item too, not just the archive
persistence. Off is exactly the old behaviour. The correctness case the PR
was written for — two spools of the same red PLA, and the slot the user
picked in the slicer thrown away — is still fixed, for anyone who asks for
it.
Force color match wins over it when both are on. Its only effect on a
fixed-printer item is the filament_overrides written onto the queue item,
and those are read inside the function a stored mapping skips, so the two
toggles sitting next to each other on the same card silently cancelled. The
dispatch now matches strictly, as asked, while the slicer's pick is still
saved onto the archive — that is what the toggle's name promises, and a
later reprint is a separate decision from this print. The queue-add fallback
applies the same rule to a request that carries force-colour overrides.
A mapping shorter than a plate's highest slot id cannot address that plate's
own slots, and _ensure_ams_mapping would have kept it anyway, since it only
rejects an all-unresolved one. Each plate now checks the length it needs and
falls back to a computed mapping if the array does not reach. Bambu Studio
sends a file-global array, so this normally never fires; it also means a
multi-plate Send All degrades safely if that ever stops being true.
The badges claimed more than they delivered. Both rendered whenever a saved
mapping existed, ignoring which printer it belonged to, while the tooltips
promised the reprint would reuse those exact spools — true only on the
printer the trays were resolved against. The queue row's flag is now
computed against that row's own printer, which is precisely when dispatch
reuses the mapping, and the archive card names the printer instead of
implying any of them will do. It hides itself when that printer no longer
exists. Retranslated in all 13 locales.
Frontend tests, which the PR had none of. The printer-scoping rule is now a
pure function rather than an inline expression, covered for the mismatched
printer, the no-printer-selected case that would otherwise compare undefined
against undefined, and malformed extra_data. The toggle's undo bookkeeping
is covered for unresolved slots, short mappings, and hand-made picks —
preserved when the toggle never wrote that slot, replaced when it did, which
is behaviour worth pinning either way.
Also reverts all three queue-mode switches when a save fails, not just the
new one; without it the card shows a setting the server rejected.
A heavy MakerWorld model — one Bambu Studio also takes a long time over —
failed after five minutes with "Slicer sidecar unreachable". The sidecar
was reachable the whole time and still slicing when we hung up on it.
SlicerApiService carried a hardcoded 300s timeout, passed to httpx as a
bare float so it covered connect, read, write and pool alike. On a single
long request that is not a health check, it is a cap on how long a model is
allowed to take. And because httpx.ReadTimeout subclasses RequestError,
expiry landed in the same handler as a refused connection and was reported
as an unreachable sidecar — so the reporter went and updated their sidecar
container, which was never the problem.
The information to do better was already being collected. _poll_progress
polls /slice/progress/{id} once a second alongside the blocking POST to
drive the live progress toast, so at minute five Bambuddy had fresh
evidence the slicer was working. It killed the request anyway.
So the read timeout comes off the HTTP call and the poller supervises
instead: the deadline moves forward on every progress update, and only
genuine silence ends the wait. A model that keeps reporting runs to
completion however long it takes. Connect and pool keep short timeouts —
a sidecar that will not accept a connection is unreachable and should
still say so quickly.
Only a *changed* progress payload counts as alive. The sidecar re-serves
its last snapshot on every poll, so counting repeats would leave the
watchdog unable to detect a stall at all.
The window is floored at three poll intervals: liveness can only be
observed as fast as the poller ticks, so anything shorter would expire in
the gap between two polls and fail every slice instantly.
New setting slicer_stall_timeout_minutes (Settings > Workflow > Slicer),
default 15, range 1-240, alongside the sidecar URL and gated on
use_slicer_api like its neighbours. Sidecars too old to report progress
have no liveness signal, so for those the same number bounds total elapsed
time — the old behaviour, configurable and no longer 300s flat. The
message says which case applies and where to change it.
SlicerTimeoutError is its own type and maps to 504, not 502: the sidecar
answered throughout, we stopped waiting. Connection failures keep
SlicerApiUnavailableError. The preview slice path gets the same treatment.
Deleting a print that belonged to a project left it on the project page as
a card with a missing thumbnail, and there was no way to remove it.
Deleting a print is a soft delete by default (#1343): the files go from
disk, the row stays so global Quick Stats keeps counting its filament,
time and cost. Every other consumer filters those rows out. The projects
module filtered none of them — the only deleted_at check in the whole file
was for LibraryFile — so a deleted print kept its project_id and kept
being listed, pointing at a thumbnail that no longer existed. The same
broken previews appeared on the overview cards, and in the timeline, where
the entry links to an archive that no longer opens. Unassigning was
impossible because the only UI that can change a print's project lives on
the Archives page, which correctly hides deleted prints: visible on the
project, unreachable from anywhere.
All eight project-scoped archive queries now filter, counts included. That
last part is a deliberate divergence from #1343, where the whole point of
the soft delete is that the contribution survives: a project is a piece of
work with a definite membership, not a lifetime total, so a project that
lists eleven prints must not claim twelve. The reasoning is recorded at
the constant so nobody later "fixes" it back.
remove_archives_from_project keeps working on hidden rows on purpose — it
is the repair path for links written before this. The BOM print_name
lookups are left alone; naming a since-deleted print is still correct.
Two more consumers had the same gap. The CSV/Excel export handed back rows
the interface says are gone — filtered at the base query, since the export
is the list you are looking at saved to a file. Per-project failure
analysis measured a failure rate against prints deleted from the project,
and disagreed with the project's own numbers; only the project-scoped
branch filters, global analysis still counts every run including orphans
as #1390 established.
Finally, the project page needed a manual reload to catch up. staleTime is
60s and the delete mutations invalidated only ['archives'], so a project
visited within the minute served its cached copy, print still there. The
project-assign mutations had the mirror-image bug: ['projects'] refreshed
the overview cards but never ['project', id]. Both now go through one
shared helper covering every project-derived key, as bare prefixes so all
cached project ids are matched.
The photo fired the moment layer_num reached total_layer_num. That edge is
where the printer *starts* its final layer, not where it finishes it: the
reporter's H2C capture shows it arriving at 92% with mc_remaining_time=2,
three minutes and seventeen seconds and one filament change before the print
actually ended, so the frame caught the toolhead mid-print over the model.
The trigger also latched _finish_photo_captured, which locked out both the
stage-22 and FINISH triggers for the rest of the print — so on firmware that
never reports an end-of-print filament unload (H2C and A1 Mini confirmed)
nothing could replace the bad frame.
Remove the last-layer trigger. The photo is now taken at the FINISH-state
trigger, which every model sends and which lands after the toolhead parks.
Since Bambu's end G-code drops the plate ~100mm just before that, restore the
framing before capturing: absolute G90/G1 Z to max_z_height + 10mm clearance,
settle, capture, then drop it back so the print is as reachable as the printer
left it. Absolute is the safety argument — that Z is a height the toolhead
occupied seconds earlier, so it is inside the travel limits by construction and
leaves the nozzle above the part, and it is unambiguous across model families
because Z is the nozzle-to-bed gap whether the bed moves or the toolhead does.
M211 is never touched (#2579). This is what #1145, #1397 and #1565 asked for.
The height is only trusted when two independent sources agree: the archive is
matched by the finished print's subtask_name by equality (not LIKE, so "Cube"
cannot resolve to "Cube v2"), and its layer count from the 3MF must match the
layer count the printer reported over MQTT. Matching on "most recent archive
for this printer" was not safe — on_print_complete pops the _active_prints
binding concurrently, and a print Bambuddy failed to archive would have
resolved to its predecessor. A wrong height is the one failure that could drive
the nozzle into the model.
The move is additionally skipped when the print height is unknown, when a queue
item is pending for the printer, when the printer has left FINISH, and when the
new finish_photo_restore_plate setting is off.
for every FINISH-state capture — which is what shipped the mid-print photo —
the bank is used only when the dispatcher recorded that it injected End G-code
into this print, since a SwapMod snippet may have ejected the plate. The flag is
handed over in two steps (mark_pending at dispatch, adopt at print start) so it
can never outlive its print: a job started from the slicer or SD card adopts
False rather than inheriting its predecessor's answer. Those prints also skip
the plate move outright, bank or no bank.
The bank now refreshes on mc_percent advances as well as layer changes, via a
new on_print_progress callback. Layer changes stop the instant the final layer
begins, which left the #1867 fallback frame stale by the whole length of that
layer; progress keeps ticking there and freezes before the End G-code runs, so
a swapped plate still cannot reach the bank. The last-layer throttle exemption
is dropped, since it would now fire a grab on every percent tick.
On the timelapse path the moment producer returns early, so the consumer does
the restore itself before its live-grab fallback — the documented usual outcome
on P1-series, where the video has not transferred by the time the notification
goes out and the shipped photo was of an already-dropped plate. The two waits
are now derived from the settle window and the video poll timeout rather than
hardcoded; at the old flat 75s that fallback was guaranteed to be cut off
mid-settle.
extract_max_z_height_from_3mf reads only a bounded prefix of the plate G-code,
since a sliced plate is routinely tens of megabytes and the header is ~40 lines.
It returns None for missing, unparseable, zero and negative values so callers
must treat "don't know" as such rather than defaulting.
Round-2 review fixes for #2700.
Blocking: the toggle didn't actually gate the archive write. archive.py's
promotion fired for any print_data carrying ams_mapping, but bambu_mqtt's
request-topic interception captures ams_mapping unconditionally for every
print source (slicer-direct LAN prints included). Since main.py's
real-printer auto-archive path forwards the full MQTT payload as
print_data, every archive on any install — VP or not — grew
extra_data.slicer_ams_mapping. Fixed by replacing the print_data-sniffing
with an explicit `slicer_ams_mapping` param on archive_print() that only
the VP-queue path (already gated on save_ams_mapping) ever passes.
Blocking: a saved mapping could get reused on a printer it was never
resolved against — tray IDs only mean something relative to one printer's
AMS layout. extra_data.slicer_ams_mapping is now stored as
{mapping, printer_id} instead of a bare array:
- add_to_queue's fallback only fires when the reprint's target printer_id
matches the mapping's origin printer.
- The frontend's archiveAmsMapping only surfaces (and the Mapping button
only appears) when the print modal's selected printer matches too.
- A model-based VP (target_printer_id=None, no MQTT bridge to any real
printer) never stamps a mapping in the first place — there's no live AMS
layout for the slicer to have resolved tray IDs against.
Also from review:
- Multi-plate archives now get the Mapping button too (the per-plate
FilamentMapping loop was missing archiveAmsMapping entirely).
- Added coverage for the previously-untested late-MQTT archive patch path
(_restamp_recent_queue_item), including the model-based-VP skip case.
- usingArchiveMapping now also resets on printer change, not just
plate/archive (it already worked via the printer-scoping above, but is
now an explicit dependency too).
- The Mapping button's revert (OFF) now undoes only the slots it itself
set, not every manual pick in scope — matches the comment above it.
- Added a comment on why negative-value slots (external spool) are
skipped rather than cleared when applying a saved mapping.
Lets a reprint reuse the AMS slot the slicer itself picked, instead of
re-deriving one from the file's static type/color.
When a Print Queue VP has "Save AMS mapping" on, the slicer's own
live-resolved ams_mapping (from the project_file MQTT command) is
persisted onto the archive as extra_data.slicer_ams_mapping. A later
reprint can reuse it via a new "Mapping" button in the filament-mapping
panel — one click snaps every slot to the saved pick, click again
reverts to auto-match. Archive cards and queue rows get an "AMS mapping
saved" badge so it's visible beforehand. add_to_queue also falls back
to the saved mapping automatically when the caller sends no explicit
ams_mapping (e.g. a plain reprint with no per-slot edits).
The queue item's own ams_mapping (used for that dispatch) is still
captured unconditionally whenever the slicer provides it — that part is
a correctness fix, not gated behind the toggle. Only the archive
persistence for future reprints is opt-in.
Split out from the original combined PR per review: this half is
genuinely opt-in and low-risk (#2684). The dispatch-time validation
gate that keeps a stored mapping honest (#1308) changes behaviour for
every existing user and will land as its own PR.
Review fixes applied:
- _extract_slicer_ams_mapping_json: dropped the unreachable `v is None`
arm and rejected bool explicitly (isinstance(v, int) accepts bool).
- Translated the Russian docstring text to English.
- save_ams_mapping's model comment moved to a trailing comment on the
column line, matching the file's convention.
- usingArchiveMapping now resets when the plate or archive changes, so
the Mapping button can't read ON against a mapping it never applied.
- Translated "Click to change slot assignment" and "Re-read".
- add_to_queue's fallback is now called out explicitly in code comments
and covered by three new integration tests (fallback fires, explicit
mapping wins, unrelated extra_data doesn't false-trigger).
Closes#2684
