Spool Studio v2.0

on GitHub

Highlights

• Complete visual redesign with the new Spool Studio v2 interface.
• Added a modern dark technical theme across the main screen, settings, startup/about screen, dialogs, dropdowns, RFID status overlays, printer mapping and Bambu dump views.
• Reworked the main workflow around existing spools, "New from selected" and fully new spool creation.
• Added a dedicated "New spool" flow for creating a completely new Spoolman spool from safe defaults.
• Added optional empty spool weight handling, including remembered brand/weight combinations.
• Added Spoolman delete support for selected spools.
• Added Spoolman catalog statistics in Settings.
• Improved RFID read/write status handling and user-facing NFC timeout messages.

Spoolman

• Create new Spoolman spools from selected filament data or from an empty default state.
• Update existing Spoolman spools from the main form.
• Delete selected Spoolman spools from the app.
• Edit remaining filament weight, empty spool weight, location, lot number and comment.
• Add custom locations directly from the location selector.
• Add custom brands from the brand selector.
• Improved URL handling in Settings: bare addresses such as 10.201.0.1:8000 are normalized automatically.
• Added Settings overview for loaded spools, active/archived spools, brands, materials, locations and colors.

RFID / NFC

• Read and write OpenSpool RFID tags.
• Improved NFC read/write waiting states and timeout feedback.
• Improved Bambu Lab RFID parsing and apply flow.
• Added a redesigned Bambu dump/debug view for easier inspection.
• Cleared transient fields correctly when applying Bambu tag data or creating a new spool from selected data.

Printer Mapping

• Redesigned Snapmaker U1 / Moonraker printer mapping dialog.
• Improved active spool mapping workflow.
• Replaced raw error dumps with clearer user-facing error messages.
• Kept Printer Mapping as a direct main-screen action because it is used frequently.

UI / Interaction

• Redesigned dropdowns with search, pinned defaults and clearer grouping.
• Improved color selection, color name recognition and HEX handling.
• Added clearer enabled/disabled button states.
• Added low-filament warning colors and remaining percentage display.
• Added compact progress/status notifications for Spoolman, RFID and printer actions.
• Adjusted Android back-button behavior to avoid accidental app exits.
• Removed the old first splash screen and updated the remaining startup/about screen to the v2 style.

Code Review / Refactoring

• Split the main ViewModel workflow into focused helpers and use cases.
• Extracted screen sections, form state, form loaders, action buttons, header, effects and settings helpers into smaller files.
• Added reusable v2 design tokens/components for the new visual system.
• Added or extended unit tests for Spoolman save/update logic, settings helpers, form state, Bambu RFID handling, color recognition and spool mode behavior.
• Cleaned up deprecated APIs and several edge-case behaviors found during Android Studio and phone testing.

Verification

• Debug build passed with assembleDebug.
• Android Studio test run passed.
• Real-device phone test passed before release preparation.
• Spoolman URL was verified with 10.201.0.1:8000.

Notes
