 ## Project Overview
 **Nome**: Print Calculator
-**Scopo**: Calcolare costi e tempi di stampa 3D da file STL in modo preciso tramite slicing reale.
+**Scopo**: Calcolare costi e tempi di stampa 3D da file STL.
 **Stack**:
-- **Backend**: Java 21 (Spring Boot 3.4), PostgreSQL, Flyway.
-- **Frontend**: Angular 19 (TypeScript), Angular Material, Three.js per visualizzazione 3D.
+- **Backend**: Python (FastAPI), libreria `trimesh` per analisi geometrica.
+- **Frontend**: Angular 19 (TypeScript).
 
 ## Architecture
 
 ### Backend (`/backend`)
-- **`BackendApplication.java`**: Entrypoint dell'applicazione Spring Boot.
-- **`controller/`**: Espone le API REST per l'upload e il calcolo dei preventivi.
-- **`service/SlicerService.java`**: Wrappa l'eseguibile di **OrcaSlicer** per effettuare lo slicing reale del modello.
-    - Gestisce i profili di stampa (Macchina, Processo, Filamento) caricati da file JSON.
-    - Crea configurazioni on-the-fly e invoca OrcaSlicer in modalità headless.
-- **`service/GCodeParser.java`**: Analizza il G-Code generato per estrarre tempo di stampa e peso del materiale dai metadati del file.
-- **`service/QuoteCalculator.java`**: Calcola il prezzo finale basandosi su politiche di prezzo salvate nel database.
-    - Gestisce costi macchina a scaglioni (tiered pricing).
-    - Calcola costi energetici basati sulla potenza della stampante e costo del kWh.
-    - Applica markup percentuali e fee fissi per job.
+- **`main.py`**: Entrypoint dell'applicazione FastAPI.
+    - Definisce l'API `POST /calculate/stl`.
+    - Gestisce l'upload del file, invoca lo slicer e restituisce il preventivo.
+    - Configura CORS per permettere chiamate dal frontend.
+- **`slicer.py`**: Wrappa l'eseguibile di **OrcaSlicer** per effettuare lo slicing reale del modello.
+    - Gestisce i profili di stampa (Macchina, Processo, Filamento).
+    - Crea configurazioni on-the-fly per supportare mesh di grandi dimensioni.
+- **`calculator.py`**: Analizza il G-Code generato.
+    - `GCodeParser`: Estrae tempo di stampa e materiale usato dai metadati del G-Code.
+    - `QuoteCalculator`: Applica i costi (orari, energia, materiale) per generare il prezzo finale.
 
 ### Frontend (`/frontend`)
-- Applicazione Angular 19 con architettura modulare (core, features, shared).
-- **Three.js**: Utilizzato per il rendering dei file STL caricati dall'utente.
-- **Angular Material**: Per l'interfaccia utente.
-- **ngx-translate**: Per il supporto multilingua.
+- Applicazione Angular standard.
+- Usa Angular Material.
+- Service per upload STL e visualizzazione preventivo.
 
 ## Key Concepts
-- **Real Slicing**: Il backend esegue un vero slicing usando OrcaSlicer. Questo garantisce stime di tempo e materiale estremamente precise.
-- **Database-Driven Pricing**: A differenza di versioni precedenti, il calcolo del preventivo è ora guidato da entità DB (`PricingPolicy`, `PrinterMachine`, `FilamentVariant`).
-- **G-Code Metadata**: L'applicazione legge direttamene i commenti generati dallo slicer nel G-Code (es. `; estimated printing time`, `; filament used [g]`).
+- **Real Slicing**: Il backend esegue un vero slicing usando OrcaSlicer in modalità headless. Questo garantisce stime di tempo e materiale estremamente precise, identiche a quelle che si otterrebbero preparando il file per la stampa.
+- **G-Code Parsing**: Invece di stimare geometricamente, l'applicazione legge direttamene i commenti generati dallo slicer nel G-Code (es. `estimated printing time`, `filament used`).
 
 ## Development Notes
-- **Backend**: Richiede JDK 21. Si avvia con `./gradlew bootRun`.
-- **Database**: Richiede PostgreSQL. Le migrazioni sono gestite da Flyway.
-- **Frontend**: Richiede Node.js 22. Si avvia con `npm start`.
-- **OrcaSlicer**: Deve essere installato sul sistema e il percorso configurato in `application.properties` o tramite variabile d'ambiente `SLICER_PATH`.
-
-## AI Agent Rules
-- **No Inline Code**: Tutti i componenti Angular DEVONO usare file separati per HTML (`templateUrl`) e SCSS (`styleUrl`). È vietato usare `template` o `styles` inline nel decoratore `@Component`.
-- **Spring Boot Conventions**: Seguire i pattern standard di Spring Boot (Service-Repository-Controller).
+- Per eseguire il backend serve `uvicorn`.
+- Il frontend richiede `npm install` al primo avvio.
+- Le configurazioni di stampa (layer height, wall thickness, infill) sono attualmente hardcoded o con valori di default nel backend, ma potrebbero essere esposte come parametri API in futuro.

 # Print Calculator (OrcaSlicer Edition)
 
-Un'applicazione Full Stack (Angular + Spring Boot) per calcolare preventivi di stampa 3D precisi utilizzando **OrcaSlicer** in modalità headless.
+Un'applicazione Full Stack (Angular + Python/FastAPI) per calcolare preventivi di stampa 3D precisi utilizzando **OrcaSlicer** in modalità headless.
 
 ## Funzionalità
 
-*   **Slicing Reale**: Usa il motore di OrcaSlicer per stimare tempo e materiale, garantendo la massima precisione.
-*   **Preventivazione Database-Driven**: Calcolo basato su politiche di prezzo configurabili nel database (costo materiale, ammortamento macchina a scaglioni, energia e markup).
-*   **Visualizzazione 3D**: Anteprima del file STL caricato tramite Three.js.
-*   **Multi-Profilo**: Supporto per diverse stampanti, materiali e profili di processo.
-
-## Stack Tecnologico
-
-- **Backend**: Java 21, Spring Boot 3.4, PostgreSQL, Flyway.
-- **Frontend**: Angular 19, Angular Material, Three.js.
-- **Slicer**: OrcaSlicer (invocato via CLI).
+*   **Slicing Reale**: Usa il motore di OrcaSlicer per stimare tempo e materiale, non semplici approssimazioni geometriche.
+*   **Preventivazione Completa**: Calcola costo materiale, ammortamento macchina, energia e ricarico.
+*   **Configurabile**: Prezzi e parametri macchina modificabili via variabili d'ambiente.
+*   **Docker Ready**: Tutto containerizzato per un facile deployment.
 
 ## Prerequisiti
 
-*   **Java 21** installato.
-*   **Node.js 22** e **npm** installati.
-*   **PostgreSQL** attivo.
-*   **OrcaSlicer** installato sul sistema.
+*   Docker Desktop & Docker Compose installati.
 
 ## Avvio Rapido
 
-### 1. Database
-Crea un database PostgreSQL chiamato `printcalc`. Le tabelle verranno create automaticamente al primo avvio tramite Flyway.
+1.  Clona il repository.
+2.  Esegui lo script di avvio o docker-compose:
+    ```bash
+    docker-compose up --build
+    ```
+    *Nota: La prima build impiegherà alcuni minuti per scaricare OrcaSlicer (~200MB) e compilare il Frontend.*
 
-### 2. Backend
-Configura il percorso di OrcaSlicer in `backend/src/main/resources/application.properties` o tramite la variabile d'ambiente `SLICER_PATH`.
+3.  Accedi all'applicazione:
+    *   **Frontend**: [http://localhost](http://localhost)
+    *   **API Docs**: [http://localhost:8000/docs](http://localhost:8000/docs)
 
+## Configurazione Prezzi
+
+Puoi modificare i prezzi nel file `docker-compose.yml` (sezione `environment` del servizio backend):
+
+*   `FILAMENT_COST_PER_KG`: Costo filamento al kg (es. 25.0).
+*   `MACHINE_COST_PER_HOUR`: Costo orario macchina (ammortamento/manutenzione).
+*   `ENERGY_COST_PER_KWH`: Costo energia elettrica.
+*   `MARKUP_PERCENT`: Margine di profitto percentuale (es. 20 = +20%).
+
+## Struttura del Progetto
+
+*   `/backend`: API Python FastAPI. Include Dockerfile che scarica OrcaSlicer AppImage.
+*   `/frontend`: Applicazione Angular 19+ con Material Design.
+*   `/backend/profiles`: Contiene i profili di slicing (.ini). Attualmente configurato per una stima generica simil-Bambu Lab A1.
+
+## Troubleshooting
+
+### Errore Download OrcaSlicer
+Se la build del backend fallisce durante il download di `OrcaSlicer.AppImage`, verifica la tua connessione internet o aggiorna l'URL nel `backend/Dockerfile`.
+
+### Slicing Fallito (Costo 0 o Errore)
+Se l'API ritorna errore o valori nulli:
+1.  Controlla che il file STL sia valido (manifold).
+2.  Controlla i log del backend: `docker logs print-calculator-backend`.
+
+## Sviluppo Locale (Senza Docker)
+
+**Backend**:
+Richiede Linux (o WSL2) per eseguire l'AppImage di OrcaSlicer.
 ```bash
 cd backend
-./gradlew bootRun
+pip install -r requirements.txt
+# Assicurati di avere OrcaSlicer installato e nel PATH o aggiorna SLICER_PATH in slicer.py
+uvicorn main:app --reload
 ```
 
-### 3. Frontend
+**Frontend**:
 ```bash
 cd frontend
 npm install
 npm start
 ```
-
-Accedi a [http://localhost:4200](http://localhost:4200).
-
-## Configurazione Prezzi
-
-I prezzi non sono più gestiti tramite variabili d'ambiente fisse ma tramite tabelle nel database:
-- `pricing_policy`: Definisce markup, fee fissi e costi elettrici.
-- `pricing_policy_machine_hour_tier`: Definisce i costi orari delle macchine in base alla durata della stampa.
-- `printer_machine`: Anagrafica stampanti e consumi energetici.
-- `filament_material_type` / `filament_variant`: Listino prezzi materiali.
-
-## Struttura del Progetto
-
-*   `/backend`: API Spring Boot.
-*   `/frontend`: Applicazione Angular.
-*   `/backend/profiles`: Contiene i file di configurazione per OrcaSlicer.
-
-## Troubleshooting
-
-### Percorso OrcaSlicer
-Assicurati che `slicer.path` punti al binario corretto. Su macOS è solitamente `/Applications/OrcaSlicer.app/Contents/MacOS/OrcaSlicer`. Su Linux è il percorso all'AppImage (estratta o meno).
-
-### Database connection
-Verifica le credenziali in `application.properties`. Se usi Docker, puoi passare `DB_URL`, `DB_USERNAME` e `DB_PASSWORD` come variabili d'ambiente.
