RepRap Generation 3 Firmware
Overview
Protocol
The protocol specification lives as a shared Google Doc. This is the authoritative document on the setup and implementation of the communication protocol that the 3rd Generation firmware uses.
The protocol itself is split into two different communication channels:
Host CPU -> Motherboard Communications
This is the link between the computer and the motherboard. The physical communication happens over a USB->TTL serial link.
Motherboard -> Slave Communications
This is the link between the motherboard and the various extruder toolheads. The physical communication happens over RS485.
