Product Details
Brand: Advanced 3D Printing

V.62 Keeps all the HUVUD you trust but adds a termination resistor+Jumper, and capacitors for a cleaner accelerometer reading!

Now at a lower price to boot!

Speaking of Boot-ing, Huvuds will come pre-flashed with CANBOOT!

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

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

Key Features (V.62):

  • 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
    • Now comes with jumper for termination resistor!
  • 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.

Changes from last produced set (V.5)

  • Added extra thermistor channel
  • Added 2x endstop channels
  • Endstops now support 5v
  • Cuttable traces on the backside now supports direct serial over 4-pin connector
  • Now comes in black!
