Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.
Add support for M579 gcode which allows setting of XYZ scaling factors during start to fine tune dimensional accuracy. Specifically to make it easier on Deltabot owners(like myself) to bring their accuracy in that last little step, without spending hours printing calibration models and fiddling with delta rod offsets per tower or trying to find clever ways to tune the steps/mm of each tower individually.
