board rev: 0.61


The HUVUD toolboard is designed to simplify wiring and configuration for extruders on klipper-based machines, particularily useful for toolchangers or extra large machines, but provides advantages for even the smallest of machines.

https://www.youtube.com/watch?v=Pi5cdTiGjwY - Great video explaining why CAN toolheads are so interesting!

Controller Board designed for use with Klipper firmware, especially for extruders to simplify wiring without losing features. Comes with complete connector set needed.

 

CAN adapters in the meantime (aff links for luke):

  • Waveshare - Good for One HUVUD
  • Innomaker - I've used this on 3x printers with a single huvud. I can work to find the firmware version with the multi-use fix.

A Portion of this sale goes to the original creator!

Key Features (V.61):

  • Simplifies Wiring for any extruder head down to 4 wires - Skip the wire bundle!

    • V+, V-, Can_H, Can_L

  • Designed for serial tunneling through CAN

    • Now comes with modifiable traces to enable direct serial thru the 4pin header
  • Uses a 32bit STM32F103 MCU

  • IO include:

    • 3x Endstop Pins W/ 5v

    • 2x Thermistor (Compatible with Thermistors and PT1000) REV 2/15/2022 Now using a .1% pullup resistor for supreme high-temperature accuracy!

    • 2 PWM fan outputs

    • Heater Output - 6A MAX

    • 4 wire Stepper Motor

    • Single-connector CAN+Power

    • USB connector for Flashing Firmware and can double as backup signaling

    • TMC 2209 stepper driver with digital current control

    • Indicator LED’s for quick status updates

    • ADXL345 onboard for easy input shaping and future features

CAN distribution board is currently in development which will combine same single-connector design for multiple toolboards on a single machine.
