The LDO Nitehawk - SB is a top - notch toolboard crafted for the Voron Stealthburner toolhead. It integrates an RP2040 MCU, TMC2209 stepper drive, and ADXL345 accelerometer on a single PCB. Its design is based on HartK’s two - piece stealthburner toolhead PCB with slight tweaks. Unlike CAN, it uses USB communication with the RPI, making software and hardware setup a breeze for those who've set up Klipper printers. Key features include easy wiring with just 24V power and a USB to the RPI, a hassle - free USB Klipper connection, a custom toolhead cable suitable for drag chain use, convenient input shaping with an onboard accelerometer, and tacho - enabled fans for extra diagnostics and safety. The Nitehawk system comprises three PCBs and an Umbilical Cable. It comes with a variety of components like a toolhead PCB, USB adapter PCB, and more. For setup details, refer to the LDO documentation.
Using the LDO Nitehawk SB Toolboard Kit is quite straightforward. First, connect the 24V power cable and the USB cable to the Raspberry Pi host as required. The custom toolhead cable makes it easy to manage the wiring, whether you're using a drag chain or umbilical configuration. To perform input shaper calibration, you can use the onboard accelerometer at any time. For the fans, connect them to the appropriate ports on the main PCB or the fan adapter. When it comes to maintenance, the fan adapter design allows you to easily detach the Stealthburner front. Be careful when handling the PCBs to avoid static damage. Keep the cables organized to prevent tangling and potential signal interference. Regularly check the connections to ensure they're secure. If you face any issues during setup or use, refer to the LDO documentation for detailed guidance.
