Picobilical kit is composed of the Toolhead PCB, Frame PCB, and Umbilical Cable – which connects the two PCBs.

  • Rear mounted toolhead PCB simplifies toolhead wiring.
  • The umbilical cable can be easily detatched from the toolhead – allowing the toolhead to be completely decoupled during maintenance.
  • On-board RP2040 microcontroller frees up ports in the main controller while greatly simplifying wiring.
  • Integrated 24V to 5V buck converter with max 5A output eliminates the need for an external 5V buck converter for the Raspberry Pi.
  • Two independent neopixel ports.
  • Selectable supply voltage (24V or 5V) for part fan and hotend fan.
  • On-board thermistor for chamber temperature monitoring.
  • Optional filament sensor input.

Description

The Picobilical by LDO is a mod designed specifically for the Voron 0 printers. The Picobilical is based on V0-Umbilical by timmit99 and retains its original advantages while introducing new features.

Overview

Picobilical kit is composed of the Toolhead PCB, Frame PCB, and Umbilical Cable – which connects the two PCBs.

  • The Toolhead PCB is a simple PCB that receives all the electrical connections on the printer toolhead and combines them into a single 14pin umbilical connector.
  • The Umbilical Cable connects the Toolhead PCB to the Frame PCB.
  • The Frame PCB is a secondary controller that processes all the signals from the toolhead PCB and communicates directly with the Klipper Host on the Raspberry Pi. This design simplifies electrical wiring because no connections need to be made to the main controller (except for the extruder motor). An additional benefit is that many ports on the main controller are now freed up, and can be used for other mods.

FAQ

What are the main differences between the Picobilical and the original V0 Umbilical mod?

  • The toolhead PCB uses a screw terminal for connecting the hotend heater instead of the original JST-XH connector. The polarity of the fan connectors are also reversed in the LDO toolheadPCB – This brings its polarity in-line with hartk’s toolhead PCBs, as well as the default polarity of most fan connectors. The Frame PCB is heavily modified and features lots of extra electronics (see features)

I already have the original V0 umbilical mod, can I reuse it?

  • Yes, the 14pin connector and its pinout is 100% compatible with the original V0 umbilical mod. So in theory, you should be able to reuse the toolhead PCB and the 14pin umbilical cable.

What material is the umbilical cable made of?

  • The 14pin umbilical cable uses high strand count UL1332 FEP cabling, most of the wires are 24AWG gauge while some of the current carrying wires are 18AWG gauge. 

I use an Orbiter / LGX Lite / Sherpa Mini extruder instead of mini Afterburner, can I use this mod?

  • Yes, since the original Mini Afterburner, Orbiter, and LGX Lite extruders all use the same stepper motor (or at least the same form factor). This mod should be compatible with those extruders.
