Hi, I'm trying to work out how to put firmware on arduino, I have downloaded collection of software called marlin for 3d printer, get compile error. But the main problem is leaning the Windows arduino program. Can't tell if sketch is compiled to arduino, also how can I see if/ which boot loader is present?, cheers

Welcome Carlos, you can post anything here relating to Arduino and maybe tell us a bit about yourself.
