Why 3MS?

Why use the 3MS when there are many other multi-material systems (MMU's) ?

Here are a few reasons:

• Simplified Design: Minimal mechanical complexity for increased reliability.
• Low Cost: A 4-filament-unit 3MS can be built for ~$150 USD
• Easily Sourceable: All the parts for the 3MS are available on Amazon. Alternatively, you can purchase a 3MS kit from West3D.
• Comprehensive Documentation: Step-by-step guides to ensure smooth setup and operation.
• Scalable: Easily expand the system to handle any number of filaments.

Requirements

To use the 3MS, your setup has to meet the following requirements:

• Run Klipper firmware
• Have SSH (PuTTY) access (99.9% of Klipper installations have this, and if you don't you really should setup SSH)
• Have one spare USB port
• Have an adapter to install a PTFE tube to the inlet of your printer's extruder.
