With the download of SkeinPyPy-Beta3 I tought this will me help start printing (after one year of trouble). Unfortunatly I have an old machine, (trying to be one of the first having an 3D-printer). I have an ATmega 1280 and so I have used the plug-and-play 'custom firmware installation'. Using the 'rerun wizard' the 'Marlin-maker' respond with 3 downloads (I dont know what to do with the last two). Then I used the 'expert' again to install the custom firmware but after selecting the HEX firmware file in the Marlinmap the printer react with an Time-out message. What to do now?
