+# Hersteller Tags - Deutsche Dokumentation
+
+## Überblick
+
+Das FilaMan NFC-System unterstützt **Hersteller Tags**, die es Filament-Produzenten ermöglichen, standardisierte NFC-Tags für ihre Produkte zu erstellen. Beim Scannen dieser Tags werden automatisch die notwendigen Einträge in Spoolman (Marke, Filament-Typ und Spule) erstellt, ohne dass eine manuelle Einrichtung erforderlich ist.
+
+## Funktionsweise der Hersteller Tags
+
+### Ablauf
+
+1. **Tag-Erkennung**: Wenn ein Tag ohne `sm_id` gescannt wird, prüft das System auf Hersteller Tag Format
+2. **Marken-Erstellung/Suche**: Das System sucht die Marke in Spoolman oder erstellt sie, falls sie nicht existiert
+3. **Filament-Typ-Erstellung/Suche**: Der Filament-Typ wird basierend auf Marke, Material und Spezifikationen erstellt oder gefunden
+4. **Spulen-Erstellung**: Ein neuer Spulen-Eintrag wird automatisch mit der Tag-UID als Referenz erstellt
+5. **Tag-Update**: Der Tag wird mit der neuen Spoolman Spulen-ID (`sm_id`) aktualisiert
+
+### Warum Hersteller Tags verwenden?
+
+- **Automatische Integration**: Keine manuelle Dateneingabe erforderlich
+- **Standardisiertes Format**: Konsistente Produktinformationen verschiedener Hersteller
+- **Lagerverwaltung**: Automatische Erstellung vollständiger Spoolman-Einträge
+- **Rückverfolgbarkeit**: Direkte Verbindung zwischen physischem Produkt und digitalem Inventar
+
+## Tag-Format Spezifikation
+
+### JSON-Struktur
+
+Hersteller Tags müssen eine JSON-Payload mit spezifischen Feldern enthalten, die **kurze Schlüssel** verwenden, um die Tag-Größe zu minimieren:
+
+```json
+{
+    "b": "Marke/Hersteller Name",
+    "an": "Artikelnummer",
+    "t": "Filament Typ (PLA, PETG, etc)",
+    "c": "Filament Farbe ohne # (FF5733)",
+    "mc": "Optional Mehrfarben-Filament Farben ohne # (FF0000,00FF00,0000FF)",
+    "mcd": "Optional Mehrfarben-Richtung als Wort (coaxial, longitudinal)",
+    "cn": "Farbname (rot, Blaubeere, Arktisches Blau)",
+    "et": "Extruder Temp als Zahl in C° (230)",
+    "bt": "Bett Temp als Zahl in C° (60)",
+    "di": "Durchmesser als Float (1.75)",
+    "de": "Dichte als Float (1.24)",
+    "sw": "Leeres Spulengewicht als Zahl in g (180)",
+    "u": "URL zum Filament mit der Artikelnummer"
+}
+```
+
+### Pflichtfelder
+
+- **`b`** (brand): Hersteller/Markenname
+- **`an`** (article number): Eindeutige Produktkennung
+- **`t`** (type): Materialtyp (PLA, PETG, ABS, etc.)
+- **`c`** (color): Hex-Farbcode ohne #
+- **`cn`** (color name): Lesbare Farbbezeichnung
+- **`et`** (extruder temp): Empfohlene Extruder-Temperatur in Celsius
+- **`bt`** (bed temp): Empfohlene Bett-Temperatur in Celsius
+- **`di`** (diameter): Filamentdurchmesser in mm
+- **`de`** (density): Materialdichte in g/cm³
+- **`sw`** (spool weight): Leeres Spulengewicht in Gramm
+
+### Optionale Felder
+
+- **`mc`** (multicolor): Komma-getrennte Hex-Farben für Mehrfarben-Filamente
+- **`mcd`** (multicolor direction): Richtung für Mehrfarben (coaxial, longitudinal)
+- **`u`** (url): Produkt-URL mit direktem Link zum Artikel zB für Nachbestellung
+
+### Beispiel Tag
+
+```json
+{"b":"Recycling Fabrik","an":"FX1_PETG-S175-1000-DAEM00055","t":"PETG","c":"FF5733","cn":"Lebendiges Orange","et":"230","bt":"70","di":"1.75","de":"1.24","sw":"180","u":"https://www.recyclingfabrik.com/search?q="}
+```
+
+## Implementierungsrichtlinien
+
+### Für Hersteller
+
+1. **Tag-Kodierung**: NDEF-Format mit MIME-Typ `application/json` verwenden
+2. **Datenminimierung**: Kompaktes JSON-Format für Tag-Größenbegrenzungen nutzen
+3. **Qualitätskontrolle**: Sicherstellen, dass alle Pflichtfelder vorhanden und korrekt formatiert sind
+4. **Testen**: Tags vor der Produktion mit dem FilaMan-System verifizieren
+
+### Tag-Größe Überlegungen
+
+- **NTAG213**: 144 Bytes Nutzerdaten (geeignet für einfache Tags)
+- **NTAG215**: 504 Bytes Nutzerdaten (empfohlen für umfassende Daten)
+- **NTAG216**: 888 Bytes Nutzerdaten (maximale Kompatibilität)
+
+### Best Practices
+
+- Markennamen über alle Produkte hinweg konsistent halten
+- Standardisierte Materialtypnamen verwenden (PLA, PETG, ABS, etc.)
+- Genaue Temperaturempfehlungen angeben
+- Aussagekräftige Farbnamen für bessere Benutzererfahrung verwenden
+- Tags vor Massenproduktion mit dem FilaMan-System testen
+
+## System-Integration
+
+### Spoolman Datenbankstruktur
+
+Bei der Verarbeitung eines Hersteller Tags erstellt das System:
+
+1. **Lieferanten-Eintrag**: Markeninformationen in der Spoolman Lieferanten-Datenbank
+2. **Filament-Eintrag**: Materialspezifikationen und Eigenschaften
+3. **Spulen-Eintrag**: Einzelne Spule mit Gewicht und NFC-Tag-Referenz
+
+### Fast-Path Erkennung
+
+Sobald ein Tag verarbeitet und mit `sm_id` aktualisiert wurde, nutzt er das Fast-Path-Erkennungssystem für schnelle nachfolgende Scans.
+
+## Fehlerbehebung
+
+### Häufige Probleme
+
+- **Tag zu klein**: NTAG215 oder NTAG216 für größere JSON-Payloads verwenden
+- **Fehlende Felder**: Sicherstellen, dass alle Pflichtfelder vorhanden sind
+- **Ungültiges Format**: JSON-Syntax und Feldtypen überprüfen
+- **Spoolman-Verbindung**: Sicherstellen, dass FilaMan mit der Spoolman API verbinden kann
+
+### Validierung
+
+Das System validiert:
+
+- JSON-Format Korrektheit
+- Vorhandensein der Pflichtfelder
+- Datentyp-Konformität
+- Tag-Größe Kompatibilität
+
+## Technische Details
+
+### Verarbeitungsalgorithmus
+
+1. Tag-Scan erkennt kein `sm_id` Feld
+2. System prüft auf `b` (Marke) und `an` (Artikelnummer) Felder
+3. `checkVendor()` erstellt oder findet Marke in Spoolman
+4. `checkFilament()` erstellt oder findet Filament-Typ
+5. `createSpool()` erstellt neuen Spulen-Eintrag

+
+### Fehlerbehandlung
+
+- Graceful Fallback bei Netzwerkproblemen
+- Detaillierte Protokollierung für Debugging
+- Benutzer-Feedback bei fehlgeschlagenen Operationen
+- Wiederholungsmechanismen für temporäre Fehler
+
+### Systemverhalten
+
+#### Bei fehlendem sm_id:
+- System prüft auf `b` (brand) und `an` (artnr) Felder
+- Falls vorhanden → Hersteller Tag erkannt
+- Automatische Erstellung von Lieferant, Filament und Spule in Spoolman
+- Tag wird mit neuer `sm_id` beschrieben
+
+#### Bei vorhandenem sm_id:
+- Fast-Path Erkennung für bekannte Spulen
+- Sofortige Gewichtsmessung ohne vollständige Tag-Analyse
+- Optimierte Performance für häufig verwendete Tags
+
+Dieses System ermöglicht eine nahtlose Integration von Hersteller-Filamentprodukten in das FilaMan-Ökosystem unter Beibehaltung von Datenkonsistenz und Benutzererfahrung.

+# Manufacturer Tags - English Documentation
+
+## Overview
+
+The FilaMan NFC system supports **Manufacturer Tags** that allow filament producers to create standardized NFC tags for their products. When scanned, these tags automatically create the necessary entries in Spoolman (brand, filament type, and spool) without requiring manual setup.
+
+## How Manufacturer Tags Work
+
+### Process Flow
+
+1. **Tag Detection**: When a tag without `sm_id` is scanned, the system checks for manufacturer tag format
+2. **Brand Creation/Lookup**: The system searches for the brand in Spoolman or creates it if it doesn't exist
+3. **Filament Type Creation/Lookup**: The filament type is created or found based on brand, material, and specifications
+4. **Spool Creation**: A new spool entry is automatically created with the tag's UID as reference
+5. **Tag Update**: The tag is updated with the new Spoolman spool ID (`sm_id`)
+
+### Why Use Manufacturer Tags?
+
+- **Automatic Integration**: No manual data entry required
+- **Standardized Format**: Consistent product information across different manufacturers
+- **Inventory Management**: Automatic creation of complete Spoolman entries
+- **Traceability**: Direct link between physical product and digital inventory
+
+## Tag Format Specification
+
+### JSON Structure
+
+Manufacturer tags must contain a JSON payload with specific fields using **short keys** to minimize tag size:
+
+```json
+{
+    "b": "Brand/Vendor Name",
+    "an": "Article Number",
+    "t": "Filament Type (PLA, PETG, etc)",
+    "c": "Filament Color without # (FF5733)",
+    "mc": "Optional Multicolor Filament Colors without # (FF0000,00FF00,0000FF)",
+    "mcd": "Optional Multicolor Direction as Word (coaxial, longitudinal)",
+    "cn": "Color Name (red, Blueberry, Arctic Blue)",
+    "et": "Extruder Temp as Number in C° (230)",
+    "bt": "Bed Temp as Number in C° (60)",
+    "di": "Diameter as Float (1.75)",
+    "de": "Density as Float (1.24)",
+    "sw": "Empty Spool Weight as Number in g (180)",
+    "u": "URL to get the Filament with the Article Number"
+}
+```
+
+### Required Fields
+
+- **`b`** (brand): Manufacturer/brand name
+- **`an`** (article number): Unique product identifier
+- **`t`** (type): Material type (PLA, PETG, ABS, etc.)
+- **`c`** (color): Hex color code without #
+- **`cn`** (color name): Human-readable color name
+- **`et`** (extruder temp): Recommended extruder temperature in Celsius
+- **`bt`** (bed temp): Recommended bed temperature in Celsius
+- **`di`** (diameter): Filament diameter in mm
+- **`de`** (density): Material density in g/cm³
+- **`sw`** (spool weight): Empty spool weight in grams
+
+### Optional Fields
+
+- **`mc`** (multicolor): Comma-separated hex colors for multicolor filaments
+- **`mcd`** (multicolor direction): Direction for multicolor (coaxial, longitudinal)
+- **`u`** (url): Product URL with direct link to the article e.g. for reordering
+
+### Example Tag
+
+```json
+{"b":"Recycling Fabrik","an":"FX1_PETG-S175-1000-DAEM00055","t":"PETG","c":"FF5733","cn":"Vibrant Orange","et":"230","bt":"70","di":"1.75","de":"1.24","sw":"180","u":"https://www.recyclingfabrik.com/search?q="}
+```
+
+## Implementation Guidelines
+
+### For Manufacturers
+
+1. **Tag Encoding**: Use NDEF format with MIME type `application/json`
+2. **Data Minimization**: Use the compact JSON format to fit within tag size limits
+3. **Quality Control**: Ensure all required fields are present and correctly formatted
+4. **Testing**: Verify tags work with FilaMan system before production
+
+### Tag Size Considerations
+
+- **NTAG213**: 144 bytes user data (suitable for basic tags)
+- **NTAG215**: 504 bytes user data (recommended for comprehensive data)
+- **NTAG216**: 888 bytes user data (maximum compatibility)
+
+### Best Practices
+
+- Keep brand names consistent across all products
+- Use standardized material type names (PLA, PETG, ABS, etc.)
+- Provide accurate temperature recommendations
+- Include meaningful color names for user experience
+- Test tags with the FilaMan system before mass production
+
+## System Integration
+
+### Spoolman Database Structure
+
+When a manufacturer tag is processed, the system creates:
+
+1. **Vendor Entry**: Brand information in Spoolman vendor database
+2. **Filament Entry**: Material specifications and properties
+3. **Spool Entry**: Individual spool with weight and NFC tag reference
+
+### Fast-Path Recognition
+
+Once a tag is processed and updated with `sm_id`, it uses the fast-path recognition system for quick subsequent scans.
+
+## Troubleshooting
+
+### Common Issues
+
+- **Tag Too Small**: Use NTAG215 or NTAG216 for larger JSON payloads
+- **Missing Fields**: Ensure all required fields are present
+- **Invalid Format**: Verify JSON syntax and field types
+- **Spoolman Connection**: Ensure FilaMan can connect to Spoolman API
+
+### Validation
+
+The system validates:
+- JSON format correctness
+- Required field presence
+- Data type compliance
+- Tag size compatibility
+
+## Technical Details
+
+### Processing Algorithm
+
+1. Tag scan detects no `sm_id` field
+2. System checks for `b` (brand) and `an` (article number) fields
+3. `checkVendor()` creates or finds brand in Spoolman
+4. `checkFilament()` creates or finds filament type
+5. `createSpool()` creates new spool entry
+6. Tag is updated with new `sm_id`
+
+### Error Handling
+
+- Graceful fallback for network issues
+- Detailed logging for debugging
+- User feedback for failed operations
+- Retry mechanisms for temporary failures
+
+This system enables seamless integration of manufacturer filament products into the FilaMan ecosystem while maintaining data consistency and user experience.

+## Modifications
+
+To reduce costs, components were sourced from AliExpress instead of Amazon. However, differences in dimensions and mounting hole spacing necessitated adjustments to the 3D-printed parts. Additionally M3 heat inserts were used to limit M4 screws to a minimum.
+![](./Images/Showcase_usermod_spitzbirne32.gif)
+---
+
+List of parts that were used:
+- Display: https://aliexpress.com/item/1005007389730469.html
+- Scale(5KG with HX711): https://aliexpress.com/item/1005006827930173.html
+- NFC Reader: https://aliexpress.com/item/1005005973913526.html

+- [VORON](https://vorondesign.com/) Heat Inserts M3 OD5mm L4mm: https://aliexpress.com/item/1005003582355741.html  - make sure to select the correct size
+
+---
+
+- **Parts are designed to be printed in ABS/ASA.** Shrinking compensation not needed.
+
+- **Display and Scale Adjustments:** The AliExpress-sourced display and scale had different dimensions and hole spacings compared to the Amazon versions. The 3D models were modified to accommodate these differences, ensuring proper fit and functionality.
+   -  measurement of my Display & Scale to check if your parts will fit can be found in the images folder
+
+- **Screw Size and Heat Inserts:** All holes originally designed for M4 screws were resized to fit M3 screws. Standard VORON heat inserts were incorporated to provide durable threading. This change standardizes the hardware and simplifies assembly.
+
+- **Display Mounting:** The display is now mounted using M3 screws with VORON heat inserts. The display's mounting holes need to be drilled to 3mm to accommodate the M3 screws.
+
+- **Scale Top Surface:** The top surface of the scale was modified to allow M3 socket head cap screws to sit flush with the 3D-printed part. This design ensures that the filament spool rests flat without interference.
+
+- **NFC Reader Mounting:** The NFC reader is also secured using M3 screws and VORON heat inserts, maintaining consistency across all components.
+
+- **Scale Base Mounting:** The only M4 screws required are for attaching the metal part of the scale to its base.
+
+## Benefits of Modifications
+
+- **Cost Reduction:** Sourcing components from AliExpress offers a more affordable alternative to Amazon, making the project more accessible.
+
+- **Standardized Hardware:** Using M3 screws and [VORON](https://vorondesign.com/) heat inserts throughout the assembly simplifies the build process and reduces the variety of required hardware.
+
+- **Enhanced Compatibility:** Adjustments to the 3D models ensure compatibility with readily available components, accommodating variations in part dimensions.
+
+## Assembly Instructions
+
+1. **Component Preparation:**
+   - Carefully drill the display's mounting holes to 3mm to fit M3 screws.
+
+2. **Heat Insert Installation:**
+   - install VORON M3 heat inserts into the designated holes in the 3D-printed housing/case for the ESP32 and Scale top → [heat insert location pictures](./Images/README.md)
+
+3. **Component Mounting:**
+   - Attach the display, scale, and NFC reader to their respective mounts using M3 screws.
+   - Secure the metal part of the scale to its base using M4 screws.
+
+4. **Final Assembly:**
+   - Assemble all components according to the original FilaMan instructions, ensuring that all modified parts fit correctly and function as intended.
+
+For detailed assembly guides and additional resources, refer to the [original FilaMan documentation](https://github.com/ManuelW77/Filaman).
+
+## Conclusion
+
+These modifications to the FilaMan project provide a cost-effective and standardized approach to building a filament management system. By sourcing components from AliExpress and adjusting the 3D models accordingly, users can achieve the same functionality at a reduced cost, with the added benefit of using uniform hardware throughout the assembly.
