The 3MS is short for MMMS, which stands for Modular Multi Material System
Happy Hare v3 Beta is RELEASED!
- New users should use the BTT MMU Board setup, as this is natively supported by Happy Hare.
- Existing 3MS mainboards configurations will be converted to be compatible with Happy Hare, but the MMU board is still recommended.
Documentation is available here

Why use the 3MS when there are many other multi-material systems?
Here are a few reasons:
- Simplified Design: Minimal mechanical complexity for increased reliability.
- Comprehensive Documentation: Step-by-step guides to ensure smooth setup and operation.
- Slicer-Agnostic: No need for custom toolchange G-Code in your slicer.
- Scalable: Easily expand the system to handle any number of filaments.
- Auto-Retries: Automatic retries on failed tool changes to reduce downtime.
- No Filament Cutter Needed: Achieve clean tool changes without the need for filament cutters.
- In Development: Rapid Tip Shaping: Achieve even faster tool changes!
With that said, there are a few reasons why you might not want to/be able to use the 3MS:
- Klipper firmware is a requirement, so Marlin and RRF setups are a no go
Think of the 3MS as an extension to your current extruder's length. It allows for switching filaments without compromising any of the benefits of your printer's extruder.
The 3MS's motors work together with your printer's extruder. This way, there won't be any additional resistance from pulling the filament through a disabled extruder. Also, unloads and loads to/from the printer's extruder are fully synchronized with the 3MS. This allows for even faster toolchanges!
I recently created a klipper plugin for the 3DChameleon after purchasing a unit. I'm sure my Chameleon could have worked if I had tuned it further, but after several months with only partial success, I gave up. I am still open to pull requests for 3dchameleon-klipper and will do my best to respond to issues there, but I won't be able to test it myself anymore.
