RepRapFirmware is object-oriented C++ firmware for controlling 3D printers and related devices on ARM Cortex-based electronics such as ATSAM4E, ATSAM4S, SAME70 and SAME5x boards. It is the firmware running on Duet controller boards and is licensed under GPLv3.
Use cases
- control a 3D printer with Duet electronics
- run RepRap-style printers on ARM Cortex microcontrollers
- customize printer firmware behavior in C++
- port printer control firmware to supported SAM processors
- manage motion, heating and G-code execution on a printer board
When to choose
- you use Duet or compatible ARM Cortex-based controller boards
- you want a mature, actively maintained open-source 3D printer firmware
- you need object-oriented C++ firmware you can extend
- you want RepRapFirmware features like its G-code dialect and platform support
When to avoid
- your board only runs AVR processors like Arduino Mega
- you prefer Marlin's large community and configuration ecosystem
- you need LPC1768/STM32 support without using the separate fork
- you want a firmware configured purely through GUI tools without C++ knowledge
