Voron 0 Umbilical PCB Kit

**PLEASE CHECK FAN POLARITY BEFORE TURNING PRINTER ON**

The Voron 0 Umbilical PCB Kit was made open source and designed by T. Abraham. More information can be found here

This kit provides an easy way for you to service, manage your cables easier and make troubleshooting problems faster on your Voron 0 3D Printer. Additional features include a chamber thermistor and Neopixel support.

All mating connectors are in matching black colors as well.

We have 2 different kits to choose from. They both include the Frame PCB and Toolhead PCB boards need for this kit.

Umbilical Kit A

This kit includes premade wires that connect from Mainboard to Frame PCB and wire harness from Frame PCB to toolhead PCB. All terminals are machine crimped to perfection every time.

We use 24AWG FEP wires for Thermistor, Fans, X Stop, Motor and 20AWG FEP wires for Heater, and Ground wires. This keeps the harness lighter and more flexible. 20AWG wires for sensors is overkill and is not required. The cables to connect the Mainboard to the Frame PCB are also the same. Heater wires use 20AWG FEP and the other wires are all 24AWG FEP.

You also get to select what color you want for the 14 Pin Umbilical Harness. You can choose any color we carry for FEP wires (Black, Red, Blue, White, Green, Yellow, Orange, Purple, Brown). Wires from Frame PCB to Main board will be made in Black FEP wires.

Cables from the Mainboard to the Frame PCB also include marked heat shrink so you know where cables need to be plugged into.

Umbilical-PCB-Heatshrink

The only crimps that are required are the connectors on the tool head. This kit will include the connectors and terminals required. Heater Cartridge, X Stop and Thermistor to the toolhead will need to be re crimped. Fan cables are usually short enough to tuck away but connectors and terminals are included if you want to redo these.

Kit A Includes

  • Umbilical PCB Kit (Frame Rev A.1 / Toolhead PCB)
  • All JST connectors in black
  • Qty 16 JST-XH crimp terminals
  • Qty 6 JST-XH 2 position connector
  • Qty 1 JST-XH 4 position connector

Umbilical Kit B

This is the do it yourself kit and includes all the required connectors and terminals to connect to the PCBs only. It is recommended for people who love crimping and find it Zen like.

Kit B Includes

  • All JST connectors in black
  • Qty 2 – Genuine 14 Pin Molex Connectors
  • Qty 28 – Genuine Molex Microfit 3 female crimp terminals

  • Qty 2 – JST-XH 3 position connector
  • Qty 4 – JST-XH 4 position connector
  • Qty 2 – Ferrule Terminals with insulation
  • Qty 2 – Ferrule Terminals with no insulation (Space is limited on Frame PCB and insulation interferes with extrusion)
