The Filament Track Switch (H2-series accessory, product code O2L-FTS) feeds
every AMS to both extruders through a two-track switch. Port full support
across the device layer, project config, and GUI.
Device / config:
- Model the switch-aware AMS binding (the set of extruders an AMS can feed
and which input track A/B feeds it), switch readiness, the O2L-FTS firmware
module, and the fun2 capability bit for checking a slice against installed
hardware.
- Register has_filament_switcher and enable_filament_dynamic_map as project
config that persists with the project and restores from a saved 3mf, and
force both back to false on every project/printer/CLI load path. Live
device sync is the only thing that sets them true.
GUI:
- Sidebar sync activates the switch from live device state, attributes each
AMS to the extruder its input track feeds, shows a floating status icon
(ready / not-calibrated), and surfaces a one-time tip / not-calibrated
warning.
- Send dialog gains a non-blocking slice-vs-hardware mismatch warning and a
blocking error when a slice needs dynamic nozzle mapping but the switch is
missing or not set up.
- AMS load/unload guards, AMS-view routing glyph + un-calibrated banner +
hidden external-spool road, and mapping-popup external-spool lockout.
- Filament pickers collapse the per-extruder split into a single deduplicated
"AMS filaments" group with a smart-assign toggle when the switch is ready.
- Firmware-upgrade panel lists the O2L-FTS accessory and its version.
- Device-provided filament-change steps (ams.cfs) drive the change-step
display when firmware sends them, including the three switch steps.
- "Load current filament" asks which extruder to feed via a
FeedDirectionDialog when the switch is calibrated.
Inert without the accessory: every path is gated on the switch being
installed (MQTT aux bit 29, default off) or ready, both project flags default
false, and the per-extruder AMS attribution is byte-identical, so AMS state,
the send/load UI, and sliced g-code are unchanged for every printer that does
not report a Filament Track Switch.
Nozzle rack data model and device-tab panel, multi-nozzle sync, per-nozzle filament blacklist, and print-dispatch nozzle mapping (DevNozzleMappingCtrl V0/V1).
