CAMMU is a universal multi material filament system, inspired by ERCF and Tradrack systems but designed to use no servo at all and keep components as accessible as possible.
A full custome controller and DIY controller is currently in the works and to be released soon. 2 stepper ports and 6 endstop connections are all that is needed if you build the 4 gate version.

- Added Build FAQ
- 05-12-2024:
- Add in basic instructions for assembly
- For the buffer, the ERCT (Cotton tail) buffer is a perfect fit. HERE
- For the software control aspect of CAMMU, we decided to not reinvent the wheel and make use of the fantastic existing software called Happy Hare by moggieuk. You can find his github page HERE
- You are requied to install Happy Hare on your existing klipper installation.
- In due time we will compile a short guide on the installation and configuration of Happy Hare
- For the sensing aspect, not only do you require a filament sensor per gate, but also require a filament sensor on your toolhead
- If you currently use the Sherpa range:
- You can find a fantastic toolhead sensor for Sherpa Mini.
- This is a fantastic toolhead sensor and can easily be wired up to your existing toolhead board if you have one.
- You can find a fantastic toolhead sensor for Sherpa Mini.
- You also require a filament cutter on your toolhead as
- The one we recommend and have tested can be found on Prusa Printables HERE
