The BLLED Controller is an accessory developed to supplement additional light for the range of FDM printers from Bambu Lab (X1-series and P1-series). 

Users can further customize the functionality by flashing their own firmware, which gives them complete control over the LED strip's behavior. The firmware is open-source and encourages users to modify the code and create their own lighting patterns and behaviors. 

The BLLED Controller communicates directly with the printer, ensuring that the LED strip's lighting is always in sync with the printer's status. It is a paramount accessory that enhances the printing experience for hobbyists, professionals, and 3D printer enthusiasts.
