BIGTREETECH Kraken – High Current, 8-Axis Motherboard


(In Stock)

Product Description:

The BIGTREETECH Kraken V1.0 stands as an advanced 32-bit printer motherboard crafted by Shenzhen Biqu Technology Co., Ltd.’s esteemed 3D printing team, specifically tailored for large-scale printers. Featuring an integrated high-voltage, high-current stepper motor driver, this motherboard streamlines the connection to high-voltage drivers, significantly reducing chassis complexity. The Kraken’s space-efficient design optimizes installation, complemented by an aesthetically pleasing silk screen printing with ID-designed heat sinks for effective auxiliary heat dissipation, seamlessly marrying form and function.

Key Features:

  • Effortless Motor Control. Equipped with 8*TMC2160 drivers, supporting a broad voltage range of 24V-60V, eliminating the need for driver installation and ensuring seamless compatibility.
  • Dual Print Head Efficiency. Utilizing the high-performance H723 chip, the motherboard enables dual print heads to operate simultaneously, facilitated by dedicated ports specifically designed to support their seamless functioning, thereby maximizing overall printing efficiency without compromising quality.
  • Versatile Connectivity Options. Featuring a reserved power supply interface for added convenience, it seamlessly integrates with external Single Board Computers (SBC) like BTT PI, as well as Raspberry Pi, providing enhanced flexibility and control.
  • Support Precision Temperature Control. Supports two channels of MAX31865 and two channels of PT100/PT1000 resistors, ensuring precise temperature control for optimal printing conditions.
  • Expanded Interface Capability. Incorporates two CAN interfaces, allowing for the concurrent connection of dual print heads to EBB (Extruder Breakout Board), enhancing versatility in 3D printing configurations.
  • Robust Motherboard Protection. Implements enhanced protection with an e-fuse circuit, fortifying the motherboard against potential risks and ensuring sustained reliability during extended usage.
