NiteHawk-36 USB Toolboard PCB by LDO Motors (Rev C)

CoreXY and Klipper users often face complex wiring and unreliable CAN bus connections that can cause intermittent toolhead communication failures, leading to print errors or downtime. The NiteHawk-36 USB Toolboard by LDO Motors simplifies toolhead wiring and improves reliability by using a USB-based connection, eliminating common CAN bus issues.

The NiteHawk-36 USB Toolboard PCB (Rev C) integrates an RP2040 MCU, TMC2209 stepper driver, ADXL345 accelerometer, and a USB port into a compact toolboard designed for advanced 3D printer builds like Voron 2.4, Trident, and Switchwire. This LDO Motors toolboard enables easy USB Klipper connection without additional hardware, supports input shaping calibration via its onboard accelerometer, and includes a secondary USB port for accessories like nozzle webcams or eddy current probes. Its custom umbilical cable combines 24V power and USB data in a drag-chain rated cable, streamlining wiring and enhancing toolhead diagnostics with a tacho-enabled hotend fan port.

Why Upgrade?

• Eliminates CAN bus wiring complexity and connection failures common in Voron 2.4 and Trident toolheads
• Enables easy USB Klipper integration without additional adapters or software
• Supports input shaping calibration anytime with onboard ADXL345 accelerometer for improved print quality
• Secondary USB port allows connection of nozzle webcams or probes without extra cables
• Custom drag-chain rated umbilical cable reduces wiring errors and improves toolhead reliability

Best For:

• Voron 2.4 and Trident builders upgrading to USB-based toolhead control
• Switchwire users seeking simplified wiring and enhanced diagnostics
• Klipper ecosystem users requiring reliable stepper and fan control on toolheads
• Advanced CoreXY builds needing integrated accelerometer for input shaping
• Users wanting secondary USB connectivity for toolhead accessories
