The WreckLab PrintHAT is a high performance controller board for the Raspberry Pi and currently the only such board on the market specifically designed around the increasingly recognized firmware called "Klipper", the new kid-on-the-block in the 3D printing community. In simple terms: Klipper's architecture is designed to distribute the computational overhead for high speed, high resolution motor steps to a powerful microcomputer (e.g. Raspberry Pi), freeing up the controller board to execute those steps with greater smoothness and precision.
The PrintHAT is directed primarily at printing enthusiasts and small businesses who are looking into (or already using) OctoPrint as one of their primary 3D printer controller interfaces, since Klipper (and PrintHAT by extension) have been extensively built around OctoPrint's well established and highly developed GUI. While the PrintHAT & Raspberry Pi work behind the scenes, Octoprint provides the user with an advanced, flexible and highly extensible Human-to-Machine controller interface, which now include integrated options for automated processes (macros), event-driven interrupts (filament runout sensors) and web cameras.
Transitioning from other controllers and firmwares? No problem! The PrintHAT comes with a dummy-proof installer package that makes installation a breeze for busy beginners, while also being customizable to the requirements of more experienced users. Whether you are in the market for a new machine or wish to upgrade your current configuration, the PrintHAt + Raspberry Pi configuration packs features, power and convenience in a small, clean form factor with minimum hassle and plenty of documentation.
NOTE: A Raspberry Pi is required to operate the printHAT and must be obtained separately. PrintHAT is compatible with Raspberry Pi v0/1/2/3, but the best performance is obtained with v2 & 3.
