Ruth's sister

Ruth's sister PIGGYBACK36 V1.0 internal power cable

SKU CH-J4KH-HAWK6

A compact piggyback board that adds a tool-head terminal for SKR2 and Octopus motherboards, supporting 36- and 42-mm stepper motors with 5 V, 12 V or 24 V power options

  • Expansion board for SKR2 and Octopus head terminal boards
  • Supports 36 and 42 stepper motors for DDB extruder use
  • Works with FLY-CDY, FLY-Gemini and all boards
  • Runs on 5 V, 12 V or 24 V power supplies
  • Compact 51 × 36 mm PCB weighing 25 g

Purpose and fit

The Ruth's sister PIGGYBACK36 V1.0 is an internal power cable accessory designed for 3D printer control boards such as the SKR2 Octopus. It connects to the head terminal board and supports both 36 and 42 stepper motors, making it suitable for builders working with compatible tool boards and extruder setups.

Before ordering

Verify that your motherboard runs KLIPPER, RRF or Marlin firmware and that your power supply can deliver 5V, 12V or 24V as required. The board measures approximately 51 by 36 millimetres and weighs 25 grams, so confirm available mounting space and that the optional fan voltage of 5V or VCC matches your cooling configuration.

Sustained operation

Under continuous use the PCB construction handles the specified supply voltages while driving up to 36 stepper motors and optional fans at 5V or VCC. The component is rated for 5V, 12V and 24V input, so thermal performance will depend on the chosen voltage and motor load rather than short bursts.

Questions about this item

Does the PiggyBack36 V1.0 board ship with any cables or mounting hardware, or do I need to source them separately?

The package includes only the PiggyBack36 V1.0 3D accessory board; cables, screws or connectors for the SKR2, Octopus, FLY-CDY or FLY-Gemini motherboards must be sourced separately.

My printer uses 42 mm stepper motors — is the PiggyBack36 V1.0 still compatible or is there a different version for that size?

The board supports both 36 and 42 stepper motors, so the same PiggyBack36 V1.0 works with either motor size.

What does the 5 V, 12 V or 24 V power supply rating mean for my actual printer setup?

It means the board can run directly from your printer’s existing 5 V, 12 V or 24 V rail, and the optional fan voltage can be set to 5 V or VCC to match your cooling fan without an extra regulator.
