No communication, but show connection green.


I've tried all baud rates available under the Repetier printer settings, but no start was acked, all the log files states that there was no start signal detected and it will force a start.

I have the delta printer kossel with arduino due and RAMPS-FD (mod) hardware and since the printer info is unknown, I can't specify the firmware version (but it's newest). I know that board it's good, because I tested with Marlin firmware and works fine.
Please help

Thanks in advance =] 


  • Are you using the right port on the due? Due has 2 ports and if you use the native port you have to say so in reset on connect in printer settings. And also firmware must be configured to use that port.
