Hi guys, im having a trouble uploading the firmware to a cerambot pro, first the arduino ide send a error messages, i believe i upload the firmware with the arduino mega connected only, then put the ramps again, the motors are now energized, but the screen doesn't show a thing.
Anyone can send more info about this?
I'm also check the modifications of the firmware, but the latest version came with the modifications specified at the manual...
i'm feeling a little disappointed with this...
Regards
