About
Marlin is open-source firmware for RepRap 3D printers and CNC machines. It handles precise motion control, multi-extruder operations, heating, and display interfaces across 8-bit AVR and 32-bit ARM boards. Users configure the codebase for their specific hardware and compile and flash it using PlatformIO or the Arduino IDE.
From the repository: “Marlin is a firmware for RepRap 3D printers optimized for both 8 and 32 bit microcontrollers. Marlin supports all common platforms. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.”
