Fysetc ERCF V1 to V2 Upgrade Kit

This kit includes all parts needed to upgrade an existing ERCF V1 kit to the new ERCF V2, ERCT and ERF. All necessary parts (except the printed ones and the controller board) are included. The upgrade will be from the 6 or 9 channel version to the new 8 channel version.

Enraged Rabbit Carrot Feeder (ERCF)

An MMU or Multimaterial Unit/Upgrade allows for the automatic change of filaments on your 3D printer. You can use it to create beautiful multi-colored prints or, if you’re lazy, simply to avoid loading filament by hand. If you are familiar with ERCF v1.1, this will serve as an overview of updates:

  • Sturdy backbone – no more flex
  • Reliable (and custom) encoder design
  • Sprung servo instead of adjustable top hats
  • Innovative Filament trap in blocks instead of magnetic gates
  • Formal filament bypass
  • Re-enforced gearbox assembly
  • Beautifully illustrated Manual (download here)
  • High Quality Step-by-step CAD (download here)
  • New integrated passive buffer system (Cotton Tail)
  • Perfect tips with Filametrix Filament cutter
  • Functional and aesthetic LED status indication
Enraged Rabbit Cotton Tail (ERCT)

When an MMU changes tool, the unloaded filament needs to be thoughtfully managed so that it doesn’t tangle. The Enraged Rabbit Cotton Tail (ERCT) buffer system is designed to attach directly to ERCF V2. It is a passive system that optimizes space and is also designed to reduce resistance in the filament path, creating a consistent system for calibration.

ERCT includes a pre-gate filament sensor to more reliably manage endless spools. It also incorporates a NEOpixel on each gate that, when driven by the Happy Hare firmware, provides functional feedback and the necessary “bling!” Enjoy!

Enraged Rabbit Filametrix (ERF)

Before the MMU can unload a filament, the tip must be prepared so that it can be cleanly loaded next time. This tip-forming process is very difficult to tune and varies based on material type, temperature, hotend type and even weather!

Introducing Enraged Rabbit Filametrix (ERF) filament cutting system: This lightweight addition to your Stealthburner tool head adds a cutting blade. When retracting, the problematic tip of the filament is simply cut off for perfect tips and no jams.

ERF also supports an optional servo operated gantry activation pin so no print area is lost with this addition. ERF designs also include the recommended integrated tool head sensor

Firmware

ERCF is designed to be used with the Happy Hare MMU firmware for Klipper which adds a set of klipper extensions for configuration setup, testing and operation of ERCF. These commands are available through the command line or macros but are perhaps best operated with an interactive UI with the optional KlipperScreen extension.

Happy Hare provides an easy installation script which has knowledge of recommended settings and will greatly accelerate the setup process.

Documentation

Building something as complex as an MMU is a challenging undertaking, but the ERCFv2 project contains an amazingly detailed and illustrated manual with step-by-step instructions. We have tried to make the process similar to fitting together a jigsaw puzzle, albeit with a few optional pieces.

CAD

A lot of work has gone into creating a quality CAD model of the project, carefully organized into folders that match the documentation! It is highly recommended that you open the CAD and hide every folder and then expose them one at a time as you work through the build.
