      I am just curious what the transfer speed should be over ethernet on the duet. I tried transferring a gcode file that was 70mb and the transfer speed was an abysmal 170 kbps.

      Is there anything that would be causing it to be this slow? It is connected to a switch which the transferring computer was also connected.

      Any ideas?

        I just tried uploading a 48Mb file to the Duet 085 in my Ormerod, and it completed at an overall rate of 718kb/sec.

        Some possible causes of slow uploading:

        • Bad or old network switch - can you confirm that is it a 100Mbps or 1Gbps switch, not an old 10Mbps switch?
        • SD card performing very slowly - try another one
        • Other traffic being received by the network causing congestion, possibly spam from outside if your network has any ports open to the Internet.

        If it is a network issue then a Wirechark trace might help to pin it down. But I suggest you try a new SD card first.
