LDO Nitehawk USB Toolhead Board

The LDO Nitehawk is a tool board specifically designed for the Voron Stealthburner toolhead. It is a toolhead PCB featuring RP2040 MCU, a TMC2209 stepper driver, ADXL345 accelerometer all integrated into one board. The form factor of the Nitehawk is based on HartK’s two piece Stealthburner toolhead PCB but with some minor changes.

Nitehawk uses USB communication with the RPI rather than CAN. So the software and hardware setup is far simpler and familiar to most people who have setup Klipper printers before

Features
  • Convenient wiring, no more complicated and error prone breakout cables – Nitehawk only requires 24V power and a USB connector to the RPI host.
  • USB Klipper connection, no additional software or hardware setup compared to CAN
  • Custom toolhead cable, a single combined USB data and power cable rated for drag chain use, but can also be used in umbilical configuration.
  • Convenient Input Shaping, run input shaper calibration at anytime with an onboard accelerometer.
  • Tacho enabled fans, both hot end and part fan ports are three pin tachometer compatible, allowing for additional diagnostics and safety.
System Overview

The Nitehawk system consists of three PCBs and the Umbilical Cable. A simplified wiring diagram is shown below:

  • The Nitehawk, this is the main PCB, which houses the MCU, stepper driver, fan drivers, and other circuits.
  • Fan Adapter, this is simple PCB receives the part fan, hot end fan, and Neopixels and connects them to the main Nitehawk PCB via headers. The main purpose of this separation is to allow the Stealthburner front to be easily detectable for maintenance.
  • Umbilical Cable, this is a custom flex cable that is rated for drag chain use. It delivers 24V power to the main Nitehawk PCB while also carrying USB data.
  • USB Adapter, this simple PCB combines 24V power from the power supply and USB data from the Raspberry Pi into a unified connection to the main Nitehawk PCB via the Umbilical cable.
Printed Parts

The Nitehawk works with the a standard Stealthburner toolhead, and is compatible with both Clockwork 2 and Galileo 2. However, a few additional custom printed parts will be needed. The printed parts are available in the Nitehawk github repo.

  • USB Adapter Mount: this is the mount for the USB adapter PCB. It is designed to be used with a standard Voron DIN clip and can be mounted in two different orientations. It also features a cover to reduce the chance of static discharge onto the PCB.
  • Cable Door: this part has been slightly modified from Hartk’s original, with a zip tie anchor added for the external chamber thermistor. The door also accepts a Mx3 Captive screw so it doesn’t get lost easily when you open the door.
  • Chain Anchor Tilted: This is tilts the drag chain ever so slightly to help it clear the left XY joint and also avoid rubbing the CT connector on the tool board.
