I have converted a Reprap Prusa I3 to a core XY printer. Everything is set up apart from the flashing of the Arduino/Ramps board. I have an older version version of Marlin installed on there. Can I just flash the latest version of Marlin on there or is there another procedure that is simpler to follow. Also can you point me in the right direction and which version to download, please. Your help will be greatly appreciated.
