ok sorry for stealing the thread here, but I finally got it to upload. I deleted all files and Arduino. installed Arduino 1.0.6 and the marlin files, changed pin number, and uploaded… on com 4… the latest Arduino version I installed earlier only listed com 1… I don’t know why, but for anyone else if you try to flash with a windows surface pro on windows 10, make sure you use Arduino 1.0.6 to say your self hours of headaches!!!!
