Marlin

Definition

Marlin is an open-source firmware designed for 3D printers and other CNC machines, which converts high-level commands into G-code that can be understood by the printer. It acts as a bridge between the user’s design intent and the machine’s mechanical movements, enabling precise control over the printing process. Marlin is widely used due to its adaptability and support for various hardware configurations, making it a key component in the G-code generation workflow.
