# FilaMan - Filament Management System
|
|
|
|
[Deutsche Version](README.de.md)
|
|
|
|
FilaMan is a filament management system for 3D printing. It uses ESP32 hardware for weight measurement and NFC tag management.
|
|
Users can manage filament spools, monitor the status of the Automatic Material System (AMS) and make settings via a web interface.
|
|
The system integrates seamlessly with [Bambulab](https://bambulab.com/en-us) 3D printers and [Spoolman](https://github.com/Donkie/Spoolman) filament management as well as the [Openspool](https://github.com/spuder/OpenSpool) NFC-TAG format.

|
|
|
|
### ESP32 Hardware Features
|
|
- **Weight Measurement:** Using a load cell with HX711 amplifier for precise weight tracking.
|
|
- **NFC Tag Reading/Writing:** PN532 module for reading and writing filament data to NFC tags.
|
|
- **OLED Display:** Shows current weight, connection status (WiFi, Bambu Lab, Spoolman).
|
|
- **WiFi Connectivity:** WiFiManager for easy network configuration.
|
|
- **MQTT Integration:** Connects to Bambu Lab printer for AMS control.
|
|
- **NFC-Tag NTAG215:** Use NTAG215 because of enaught space on the Tag
|
|
|
|
### Web Interface Features
|
|
- **Real-time Updates:** WebSocket connection for live data updates.
|
|
- **NFC Tag Management:**
|
|
- Write filament data to NFC tags.
|
|
- uses NFC-Tag Format of [Openspool](https://github.com/spuder/OpenSpool)
|
|
- so you can use it with automatic Spool detection in AMS
|
|
- **Bambulab AMS Integration:**
|
|
- Display current AMS tray contents.
|
|
- Assign filaments to AMS slots.
|
|
- Support for external spool holder.
|
|
- **Spoolman Integration:**
|
|
- List available filament spools.
|
|
- Filter and select filaments.
|
|
- Update spool weights automatically.
|
|
- Track NFC tag assignments.

|
## Detailed Functionality
|
|
|
|
### ESP32 Functionality
|
|
- **Control and Monitor Print Jobs:** The ESP32 communicates with the Bambu Lab printer to control and monitor print jobs.
|
|
- **Printer Communication:** Uses MQTT for real-time communication with the printer.
|
|
- **User Interactions:** The OLED display provides immediate feedback on the system status, including weight measurements and connection status.
|
|
|
|
### Web Interface Functionality
|
|
- **User Interactions:** The web interface allows users to interact with the system, select filaments, write NFC tags, and monitor AMS status.
|
|
- **UI Elements:** Includes dropdowns for selecting manufacturers and filaments, buttons for writing NFC tags, and real-time status indicators.
|

## Important Note
|
|
You have to activate Spoolman in debug mode, because you are not able to set CORS Domains in Spoolman yet.
|
|
|
|
```
|
|
# Enable debug mode
|
|
# If enabled, the client will accept requests from any host
|
|
# This can be useful when developing, but is also a security risk
|
|
# Default: FALSE
|
|
#SPOOLMAN_DEBUG_MODE=TRUE
|
|
```
|
|
|
|
|
