Marlin 2.1.2.4

Marlin is a straightforward Open Source firmware designed for the RepRap family of 3D printers.

It is reliable, extensible, and adaptable, making it the go-to for commercial 3D printer vendors and hobbyists. Marlin runs on inexpensive 8-bit Atmel AVR microcontrollers. It additionally includes the added support for 32-bit and ARM-based boards. Most Marlin builds are generally small enough for use on a headless printer with only modest hardware, and features can be enabled as required. That makes it an excellent choice for 3D printing enthusiasts who don't have an unlimited budget to satisfy their hobby needs.

Marlin Firmware runs on the 3D printer’s mainboard, managing all its real-time activities. It coordinates the heaters, steppers, sensors, lights, LCD display, buttons, and everything else involved in the 3D printing process. The author's site has an extensive introduction section to get you started.
