The Buddy Control Board is the main electronic board used on several Original Prusa 3D printers. It manages the machine's essential functions: stepper motor drive, thermal control of heating elements, sensor management, communication with the user interface, and processing of FDM print operations.
Developed for the Prusa ecosystem, this control board integrates the electronics required for the coordinated operation of the printer's mechanical and thermal subsystems. It can be used as part of a defective board replacement or an advanced maintenance operation.
Electronic architecture and machine management
The Buddy Board centralises connections related to motor axes, fans, thermistors, heating elements, and detection devices present on compatible printers. Its architecture is designed to ensure stable communication between the firmware and the various machine components.
It contributes to maintaining movement precision, thermal control, and extrusion regularity during extended print cycles. Board replacement must be carried out in accordance with the technical procedures specified by the manufacturer.
Maintenance and integration
This electronic board is supplied as an original spare part for compatible platforms equipped with the Buddy architecture. It integrates directly into the assemblies specified by Prusa Research and restores the printer's drive and control functions without structural modification of the system.
