Marlin is a Windows program for controlling RepRap 3D printers. There is support for headless devices. Users can enable only features required for the specific task.

Movement configuration

You are able to program more than 150 G-code commands. The movement suite includes options for creating lines, arcs and complex curves.

There is a smart motion system with capabilities like lookahead, custom interruptions and linear acceleration. The Cartesian, Delta, SCARA, and Core/H-Bot kinematics are fully supported.
