LDO Nitehawk-SB Toolboard

The LDO Nitehawk-SB Toolboard is a specialized toolboard designed specifically for the Voron Stealthburner toolhead. This compact and feature-rich board integrates essential components into one cohesive unit, streamlining your 3D printing setup.

Key Features:

  1. Integrated Components:
    • RP2040 MCU: The heart of the Nitehawk-SB, providing processing power and control.
    • TMC2209 Stepper Driver: Ensures precise and quiet motor movement.
    • ADXL345 Accelerometer: Enables convenient input shaping calibration.
  2. Form Factor:
    • The Nitehawk-SB’s form factor is based on HartK’s two-piece Stealthburner toolhead PCB, with minor modifications. It fits seamlessly into existing setups.
  3. Simplified Wiring:
    • Say goodbye to complicated breakout cables! The Nitehawk-SB requires only a 24V power supply and a USB connection to the Raspberry Pi host.
    • No additional software or hardware setup compared to CAN communication.
  4. Custom Toolhead Cable:
    • A single combined USB data and power cable, designed for drag chain use but adaptable for umbilical configuration.
  5. Convenient Input Shaping:
    • The onboard accelerometer allows you to run input shaper calibration at any time.
  6. Tacho-Enabled Fans:
    • Both the hotend and part fan ports support three-pin tachometer fans, enhancing diagnostics and safety.

System Overview:

The Nitehawk-SB system consists of three main components:

  1. Nitehawk-SB (Main PCB):
    • Houses the MCU, stepper driver, fan drivers, and other essential circuits.
    • USB communication with the Raspberry Pi.
    • Simplified setup for Klipper users.
  2. Fan Adapter:
    • Connects part fans, hotend fans, and neopixels to the main Nitehawk-SB PCB via headers.
    • Allows easy detachment of the Stealthburner front for maintenance.
  3. Umbilical Cable:
    • Custom flex cable rated for drag chain use.
    • Delivers 24V power to the main Nitehawk-SB PCB while carrying USB data.
  4. USB Adapter:
    • Combines 24V power from the supply and USB data from the Raspberry Pi.
    • Unified connection via the Umbilical cable.

Printed Parts:

Nitehawk-SB works seamlessly with standard Stealthburner toolheads (compatible with both Clockwork 2 and Galileo 2). However, a few additional custom printed parts are needed:

  1. USB Adapter Mount:
    • Designed for use with a standard Voron DIN clip.
    • Features a cover to prevent static discharge.
  2. Cable Door:
    • Modified from HartK’s original design.
    • Includes a zip tie anchor for the external chamber thermistor.
  3. Chain Anchor Tilted:
    • Slightly tilts the drag chain to avoid rubbing against the CT connector on the toolboard.
