 - **Status badges on printer card**: SD Card (green / red), Enclosure Door (green / yellow — X1/P1S/P2S/H2*), Airduct Mode (cooling / heating)
 - **Force Refresh** menu item — request a full status push from the printer without reconnecting
 - **Maintenance Mode** — put a printer "out of service" without removing it. Toggle from the card's three-dot menu, the in-card amber banner, or the Edit Printer dialog; the printer disconnects MQTT, drops out of queue dispatch, the scheduler, model-based filament lookups, metrics, and notifications until you take it out again. The card stays visible (amber wrench banner + Exit button) so the printer never disappears from your dashboard. Useful for parallel Bambuddy installs sharing the same hardware, printers under repair or awaiting parts, and temporary suspension.

 - **Assignment verification** — When you assign a spool to a slot, Bambuddy reads the slot back and confirms the printer actually took it
 - **Lost K-profiles put back** — If a slot loses its K-profile (for example after the printer restarts), Bambuddy re-selects the spool's stored profile while the printer is idle and right before a queued print starts
 - AMS info card (hover for serial number, firmware version) with custom friendly names that persist across printers
-- **AMS remote drying** — Start, monitor, and stop drying sessions for AMS 2 Pro and AMS-HT directly from the Printers page with filament-based temperature/duration presets, optional spool rotation; automatic PSU detection and HMS power error reporting. Rotate-spool toggle is disabled per-AMS when any tray has filament threaded into the feed tube (the AMS mechanism is locked there — rotating would jam the filament)

 - **Queue auto-drying** — Automatically dry filament between scheduled prints when humidity exceeds threshold; configurable presets per filament type, optional blocking mode
 - **Ambient drying** — Automatically keep filament dry on idle printers based on humidity, regardless of whether prints are queued. It waits until the humidity stays high, so a brief spike doesn't start a cycle
 - **Continue drying while printing** — On capable hardware (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+), auto-drying can keep running during a print. Default off, opt-in toggle in Settings → Print Queue. Drying temperature is automatically capped 5°C below the idle preset (floor 40°C) to protect spools inside the hot enclosure

+- Configurable drying presets per filament type (temperature & duration for AMS 2 Pro and AMS-HT; the AMS 3H dryer uses the AMS-HT values)
 - **Per-filament humidity threshold** — Set a different humidity trigger per filament type (e.g. Nylon at 20%, PLA at 60%, ASA at 30%) instead of one global value. Mixed-material AMS units use the most-restrictive threshold across the loaded spools so a single PLA + Nylon unit triggers at Nylon's level. Drives both the auto-drying scheduler and the hourly humidity alarm so the two can never disagree on whether a unit is "too humid"
 - Dual external spool support for H2D (Ext-L / Ext-R)
 - **Filament Track Switch inlet binding** — Shows which AMS feeds which FTS inlet, and K-profiles follow the inlet

 - Shortest Job First scheduling (SJF toggle on queue page — scheduler picks shorter prints first, with starvation guard)
 - Queue Only mode (stage without auto-start)
