Marlin (firmware)

Marlin is a open source firmware for RepRap and other fused deposition modelling (FDM) 3D printers based on the Arduino platform.[1][2][3] The firmware runs on the 3D printer's control board and manages all of the machine's the real-time activities including movement through the stepper drivers, heaters, sensors, lights, bed levelling, LCD displays and buttons.[4] Marlin supports many different boards and many designs of 3D printer including Cartesian printers, delta printers, SCARA printers and other less conventional designs like Hangprinter.[2][5]

History

Marlin was first created in 2011 for the RepRap and Ultimaker printers; it claims to be the most widely used 3D printing firmware in the world.[2]

Development

The firmware is created by a community of contributors, with Scott Laheine (aka Thinkyhead) as the main developer.[6][3] Marlin 2.0 will support 32bit boards with much of the development in progress.[7] Marlin is also used for many other kinds of machine including SLA and SLS 3D printers, CNC mills and egg painting robots.[3][8][9]

License compliance

Marlin uses a GPL license which requires that organisations and individuals share their source code when modifying or expanding the code, some users have not been compliant with the license which has led to distributors removing their products.[10]

Usage

Marlin firmware is used by many different manufacturers, some of which comply with the license.
