Enraged Rabbit Carrot Feeder V3 (ERCF V3) Kit - (ERCF V3 - 8 Channel + ERCT + ERF + THS))

Multimaterial 3D printing enthusiasts in the Voron and Klipper communities face challenges with filament management and toolhead switching, often resulting in failed prints or complex setups. Without a reliable multi-material unit, users struggle with filament jams, inconsistent extrusion, and limited material options.

The Enraged Rabbit Carrot Feeder V3 (ERCF V3) Kit is a refined multi-material upgrade designed primarily for Voron 2.4 and other Klipper-based CoreXY printers. This kit includes an 8-channel feeder, integrated filament buffer (ERCT), filament cutter (ERF), and toolhead sensor (THS), enabling seamless switching between multiple filaments on a single direct drive toolhead. Developed in partnership with Trianglelab, the ERCF V3 improves reliability, simplifies construction, and leverages Happy Hare firmware for advanced MMU control, making it ideal for users seeking high-performance multi-material printing on Voron and compatible builds.

Why Upgrade?

• Voron 2.4 and Klipper users gain reliable multi-material feeding with up to 8 filaments, reducing print failures due to filament jams or misfeeds.
• Integrated filament buffer and cutter improve filament handling and tip preparation, essential for clean filament changes across diverse materials.
• Compatible with Happy Hare firmware, enabling advanced MMU control and seamless integration with Klipper Screen for intuitive management.
• Modular design simplifies construction and maintenance compared to earlier ERCF versions, enhancing long-term reliability.
• Supports a wide range of filament types and toolhead configurations common in CoreXY and Voron ecosystems.

Best For:

• Voron 2.4 builders upgrading to a robust multi-material unit with advanced filament management.
• Klipper-based CoreXY printer owners seeking to expand filament options without complex hardware changes.
• Users requiring precise filament tip cutting and buffering for high-quality multi-material prints.
• Enthusiasts wanting to leverage Happy Hare MMU firmware for enhanced multi-material control.
• CoreXY and Voron community members looking for a well-supported, community-endorsed MMU solution.

Pair With the Right Filament

The ERCF V3’s reliable multi-material feeding system pairs best with filaments that benefit from precise extrusion control and clean transitions.

• PLA Filament — ideal for multi-color and multi-material prints with consistent flow.
• TPU Flexible Filament — compatible with direct drive setups enabled by ERCF for flexible material printing.
• PETG Filament — reliable extrusion with multi-material setups for durable prints.
