 Adhere NFC stickers on all your filament. Build an ESP32 OpenSpool reader and place it next to your printer. 
 Touching the filament to the reader will automatically update your Bambu Printer filament settings. 
 Almost as seamlessly as if you were using Bambu filament with an AMS. 
 
-## Objectives
 
-- Make it so easy to put RFID stickers on filament spools that your grandma could do it. 
-- 100% programable using just a modern iphone/android (no RFID programmer or scripting).
-- Change filament in 10 seconds using 1 hand. 
-- 100% reliability so that filament can be changed with your eyes closed.

 ### 🧬 OpenSpool Protocol
 
-OpenSpool aims to use the simplest possible protocol for RFID tags. All you need is a [13.56Mhz RFID tag](https://a.co/d/5ojDUNk) that supports NDEF records (NFC Tags) and has at least 500 bytes of memory. NTAG 215/216 are a great choice. Purchasing links provided below.

-### Caution of Fakes
-
-There is a plethora of fake D1 Mini S2 microcontrollers and PN532 RFID readers in the market. 
-For the D1 Mini microcontroller, you need the `ESP32-S2FN4R2` not the `ESP32-S2FH4`
-For the PN532 RFID reader, you need the model that contains the silkscreen. 
-
-
-While temping to buy a fake/clone esp32 or PN5432 at a lower cost, they inevitibly cause headaches as they are less reliable at reading NFC tags. 
-Purchasing at reputable vendors is highly recomended. 
-If you do find a cheaper price and have verified reliablity, please let us know.
