This RepRap firmware is a mashup between <ahref="https://github.com/kliment/Sprinter">Sprinter</a>, <ahref="https://github.com/simen/grbl/tree">grbl</a> and many original parts.
Derived from Sprinter and Grbl by Erik van der Zalm.
Sprinters lead developers are Kliment and caru.
Grbls lead developer is Simen Svale Skogsrud. Sonney Jeon (Chamnit) improved some parts of grbl
A fork by bkubicek for the Ultimaker was merged, and further development was aided by him.
Marlin has a GPL license because I believe in open development.
Please do not use this code in products (3D printers, CNC etc) that are closed source or are crippled by a patent.
