maziggy 61e2841d16 Correct the drying settings path and the print-drying comment (issue #2518)
The changelog named Settings -> Print Queue -> Auto-Drying; the toggle
lives in the Queue Auto-Drying card under Settings -> Workflow. The
scheduler comment and a test docstring called print_drying a permission
overlay rather than a trigger, but since #1816 it starts mid-print
cycles on its own regardless of queue state.

maziggy 4440738904 fix(drying): dry a composite spool as its base material (issue #3067)
The reporter's AMS-HT would not auto-dry PA6-CF, and drying the same spool by
hand worked. The scheduler reduced a tray to a preset key by splitting on spaces
only, so "PA6-CF" stayed "PA6-CF", matched none of the eight rows the preset
table has, and the tray was read as holding nothing worth drying. The AMS was
then passed over on every scheduler sweep, silently, because every caller reads
"no row" as "nothing to do for this tray".

It was never only nylon. Of the 41 types a printer can report, 33 had no row
under that rule, and 20 of those have a base material sitting right there: every
-CF, -GF and -AERO variant of PLA, PETG, ABS, ASA, PC and PA.

Doing it by hand worked because the drying popover has resolved composites since
exact key first, so a row the user added for the exact type still wins, then the
suffix, then an alias map reading PA6, PA11, PA12, PAHT, PPA and Nylon as PA.

PPA is the one alias that is a judgement rather than a spelling. Polyphthalamide
is a distinct polymer, not a grade of nylon -- but it is an aromatic polyamide,
it takes up moisture the same way, and PA's row is the hottest the table has.

A material with no row and no alias is still skipped rather than dried at a
number nothing here can source. That is where this parts company with the
popover, which falls back to PLA because a dropdown has to show something.

The table is user-editable JSON, so a preset row can be present and empty. That
has always meant "skip this material" and still does: the temp and hours reads
fall back per field to 55C/12h, which would dry a PLA spool at 55 degrees.

Two more callers had the same line and move with it: per-filament humidity
thresholds, where the override set for a material never applied to that
material's composites, and the chamber preheat target, which had the suffix half
of this from #2902 but not the aliases.

The preheat test for that half reimplemented the lookup inline rather than
calling it, so it would have passed whatever the function did. It calls it now.

maziggy 71709c16aa Stop tearing down AMS drying for a print that cannot start (#2801)
A printer in FINISH with an unacknowledged plate and something pending in
its queue stopped and restarted drying once per scheduler tick, for as
long as the plate stayed unacknowledged. The reporter's Home Assistant
history recorded about 2000 state changes over ten days. No cycle ever
ran long enough to remove moisture, and cycles the user had started by
hand on other AMS units of the same printer were torn down with it.

Two concerns had become tangled. Plate-clear answers "is the bed ready
for the next job" and says nothing about whether the AMS may heat. The
gap between a finished print and the acknowledgment is when drying is
most useful -- the printer is free and nobody is waiting on it -- and
leaving the plate unacknowledged is also how people hold the queue by
hand, so the hold was costing them the drying it should have enabled.

Four faults, all in print_scheduler.

The "print takes priority" stop sat inside the not-idle branch. Drying is
not one of the things _is_printer_idle looks at, so stopping a cycle can
never turn a non-idle printer into an idle one: the stop was futile every
time it fired, and never fired on the dispatches where it was supposed to
mean something. It now runs when the printer is actually dispatchable,
and only where the model cannot dry through a print -- #2758 settled that
capable hardware should keep its cycle.

mid_print was inferred from busy_printers, which means "the queue could
not dispatch here this pass", not "is printing". A plate-held printer was
therefore treated as printing: the mid-print spool-protection cap
silently lowered its drying temperature, the cycle was logged as
(mid-print) in FINISH, and it bypassed the very gate meant to hold it.
busy_printers keeps its dispatch role; auto-drying now gets a narrow set
snapshotted before the item loop -- running, held post-dispatch, or
mid-upload -- and mid_print comes from the printer's own state. The
interlock comment at the seed already documented this hazard and worked
around it by staying out of the set; this generalises that instead of
adding a third special case. The other call site was already passing the
narrow set, so the wide one was the inconsistency.

_stop_drying sent a stop to every AMS reporting dry_time > 0. One
auto-dried unit was enough to kill a manual cycle on a different unit of
the same printer, contradicting the contract _sync_drying_state already
documents: the entry gate only knows about cycles Bambuddy began, so the
action must not reach past them. Consequence worth stating -- after a
restart Bambuddy cannot prove a running cycle is its own, so it leaves it
alone rather than risk stopping somebody's manual dry.

Fourth, and the reason #2770's guard did not catch this: a reading at or
below the threshold popped the unit's whole entry, ended_at included, so
the 30-minute re-arm cooldown went with it. An AMS reads higher warm than
cool, which is #2770's own finding, so a unit a point or two above the
threshold dipped below it as it cooled, wiped its history, and re-armed
immediately. Lifting a suspension now clears the judgement and keeps the
clock.

queue_drying_block changes behaviour as a result. It previously had no
effect on dispatch at all -- both branches skipped anyway, and it only
decided whether drying was needlessly killed. With the stop on the
dispatch path it now does what it says: a queued print waits for a
running cycle. Off by default.

Reported by @superflyer11, who traced both defects to the line and
brought ten days of external sensor history to date the cadence.

maziggy 328bac450a Stop auto-drying re-arming into a threshold it can never reach (#2770)
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.

maziggy 53ae5fb620 fix(drying): don't stop a running AMS dry on an unreliable humidity re-check (#1892)
Auto-drying stopped manually started (and pre-restart) AMS drying cycles
after exactly 30 minutes. The already-drying branch in _check_auto_drying()
applied a humidity-based auto-stop despite its own "track but don't stop"
comment, and the humidity re-check is unreliable: RH drops steeply in heated
air, so the sensor reads ~15-20% within minutes of the dryer starting even
with saturated filament. humidity <= threshold was thus effectively always
true, and the _min_drying_seconds=1800 floor pinned the stop to the 30-minute
mark. This also truncated Bambuddy's own preset-duration dries.

Remove the humidity-based early-stop entirely: a running dry now runs to its
configured duration (firmware stops it). Scheduling stops (print priority,
queue no longer needing the dry) are unchanged via _stop_drying(). Drop the
now-unused _min_drying_seconds.

maziggy 8d6f701f1d feat(drying): continue drying while printing + gate rotate-spool when tray loaded (issue #1816)
Continue Auto-Drying while a print is running on capable hardware.
  New Settings > Print Queue > "Continue drying while printing" toggle
  (default OFF). Extends _check_auto_drying in print_scheduler.py to
  evaluate running printers when supports_drying_while_printing(model,
  firmware) returns true. Strict allowlist verified per Bambu wiki
  release notes for "Print While Drying" / "printing while filament is
  drying": H2D 01.03.00.00+, H2C/H2S/P2S/H2D Pro 01.02.00.00+, X2D/A2L
  01.01.00.00+, X1C 01.11.02.00+. P1*, A1, A1 Mini, X1 (non-C), X1E
  intentionally excluded. Mid-print drying temperature is capped at
  max(40, preset_temp - 5) to protect spools from heat damage inside the
  hot enclosure during a print, matching Bambu's own "lower drying
  temperature during printing" guidance.

  Rotate-spool toggle in the drying popover is now disabled when any tray
  in the targeted AMS has filament threaded into the feed tube
  (tray.state === 11). The whole AMS rotates as one mechanism, so a
  single loaded slot locks the entire unit. Previously the toggle was
  always clickable and the firmware rejected with dry_sf_reason=[3]
  (ConsumableAtAmsOutlet) after the click. The first cut keyed on the
  printer-level tray_now but missed the H2D's typical post-print state
  where tray_now resets to 255 while filament stays in the tube — the
  per-tray state field reports it correctly. Submission also clamps
  rotateTray off so a stale-true state from a previous AMS can't leak
  through.

  Backend: supports_drying_while_printing in printer_manager.py covers
  display names and internal SSDP/MQTT codes (O1D, O1E/O2D, O1C/O1C2,
  O1S, N6, BL-P001, N7, N9). New print_drying_enabled boolean in
  settings schema. Frontend: toggle on SettingsPage, gate + clamp on
  PrintersPage drying popover using existing amsData cache. i18n: 3 new

  transitions. Full backend pytest -n 30 green (4251/4251), ruff clean,

maziggy 68b9d741d9 feat(humidity): per-filament humidity threshold for auto-drying + alarms (#1605)
Reporter @thenewguy runs an engineering farm with one AMS per material
  (PLA, ASA, Nylon, PVB, HIPS) — Bambuddy's single global ams_humidity_fair
  threshold (default 60%) was driving both the queue / ambient auto-drying
  trigger AND the hourly humidity alarm uniformly, which is wrong for
  multi-material setups where Nylon wants <10% and PLA is fine at 60%.

  Drying RUN parameters were already per-filament via drying_presets;
  this commit adds the missing per-filament TRIGGER.

  New setting ams_humidity_thresholds — JSON map of filament-type to
  threshold percent with a "default" key for unknown / unmapped types.
  Empty / unset → both consumers fall back to ams_humidity_fair so the
  upgrade is silent.

  Resolver lives in PrintScheduler.resolve_humidity_threshold(trays,
  thresholds, fallback) — picks the lowest (most-restrictive) threshold
  across all loaded tray types, matching the conservative-params strategy
  _get_conservative_drying_params already uses for temp / hours. Empty
  tray slots contribute no constraint; all-empty AMS falls through to the
  "default" key. Filament names normalized to uppercase base (so
  "PLA Basic" / "pla basic" both map to PLA).

  Two consumer sites rewired through the same resolver so the scheduler
  and the alarm path can never disagree about whether an AMS is "too
  humid":
    - print_scheduler.py::_check_auto_drying — per-AMS humidity comparison
      for start / stop / skip decisions.
    - main.py AMS sensor / alarm worker — hourly humidity alarm notifier.

  UI: new table in Settings → Workflow → Auto-Drying, below the existing
  Drying Presets table. Default row + 8 default filament types
  (PLA / PETG / TPU / ABS / ASA / PA / PC / PVA) pre-filled from the
  current ams_humidity_fair value so the editor starts sensibly.

  Input pattern: draft-on-edit / commit-on-blur (transient humidityDrafts
  state per row). onChange only updates the draft; onBlur (and Enter)
  parses + clamps to [5, 95] + commits. Empty value on blur clears the
  override and falls back to default. Caught mid-PR via a typing test:
  the naive per-keystroke clamp snapped "3" → 5 before the user could
  type the second digit of "30".

  Setting is in the public _UI_PREFERENCE_FIELDS allowlist (same rationale
  as drying_presets and ams_humidity_fair — non-sensitive integer map,
  no SETTINGS_READ permission required for badge-color rendering).

maziggy 14855ba8f4 Add ambient drying mode and fix block mode humidity auto-stop (#292)
Ambient drying: automatically dry filament on idle printers when
  humidity exceeds threshold, regardless of queue state. Separate toggle
  from queue auto-drying — both can run simultaneously. Uses the same
  presets, humidity threshold, and power constraint detection.

  Fix: block mode (wait for drying) previously skipped the humidity
  auto-stop check for already-drying printers, causing drying to
  continue indefinitely. Now only prevents starting new drying.

maziggy cffba4a911 Add queue auto-drying, configurable drying presets, and AMS PSU detection (#292)
Queue auto-drying: scheduler automatically starts drying on idle printers
  with scheduled queue prints when AMS humidity exceeds the configured
  threshold. Uses conservative parameters (lowest temp, longest duration)
  for mixed filaments. Drying stops when humidity drops below threshold
  (30-minute minimum prevents oscillation), when scheduled items are
  removed, or when the feature is disabled. Optional "block queue" mode
  delays the next print until drying completes.

  Configurable presets: temperature and duration per filament type,
  editable in Settings → Print Queue, used by both manual drying popover
  and queue auto-drying. Separate presets for AMS 2 Pro (n3f) and AMS-HT
  (n3s) reflecting different heating capabilities.

  PSU detection: drying button disabled with tooltip when dry_sf_reason
  indicates insufficient power. Parses drying status bits and dry_sf_reason
  from AMS info hex string via MQTT.

  Backend: print_scheduler.py (+316 lines), bambu_mqtt.py, printer_manager,
  schemas, settings route. Frontend: PrintersPage drying presets prop,
  SettingsPage drying config UI, i18n (7 locales). Tests: 27 new tests in
  test_scheduler_auto_drying.py covering conservative params, presets,
  state sync, stop logic, minimum drying time, and auto-stop regressions.
