        Firmware Name: RepRapFirmware for Duet Ethernet
        Firmware Electronics: Duet Ethernet 1.0
        Firmware Version: 1.18.1 (2017-04-09)
        Web Interface Version: 1.15a

        Nothing else is close to the number that the router assigned it.

        Can you confirm that you only have one Duet on the network? I had problems connecting to a Duet Ethernet yesterday, until I realised that I had a Duet 0.6 on the same network and they were both using the default MAC address.

          I only have one board, and only one is listed on the router info screen. it has My computer, my laptop when its on, my phone and the Duet board. short list so its easy to spot.

          Another oddity showed up this morning, the small print I was doing, a replacement part was nearly finished. I could see the part was on the last few layers. yet the DWC told me I was only 56.6% done. It has been spot on before. Down right scary in how close it has been till this. I will be keeping an eye on it.

            That usually means that you have a G1 Z command in your end gcode to raise the print head when the print is complete, and that command is confusing the object height detection. The remedy is to add a comment starting with ;E to that line.

              I keep losing connection with the board. I just get the standard AJAX message and no explanation.

              Are you connecting using a DNS name, or directly via IP address? I was having similar issues when connecting via a DNS host name, and someone else here suggested I try via IP address, as the mDNS responder might be having issues. I've switched to connecting via IP address only, and have not had an unexplained disconnection since that time.

                    That shouldn't cause any problems, it's when you have a G1 Z line in your closing script that the object height is likely to be read incorrectly, because the firmware looks for the last G1 Z line in the file and assumes that indicates the start of the last layer.

                      So then might it not be a good idea to but code in the starting script to tell it where it is? Maybe a G30, or do G30 and input that value somehow? Is there something else in my code throwing it off. I used the ones I had for an i3 as a basis. This is my first Delta machine so things might not translate the way I think they do.

                      open script
                      G28 ; home all axes
                      M280 P3 S10 I1 ; DROP PIN
                      M98 Pbed.g

                      close script
                      G1 E-13.0 F9000 ;E
                      G90
                      G0 Z400 F1800
                      M104 S0 ; turn off extruder
                      M140 S0 ; turn off bed
                      M106 S0
                      M84 ; disable motors

                        The line that is confusing the firmware is this one:

                        G0 Z400 F1800

                        If you append ";E" or "; E" (without the quotes) to that line, that should avoid the problem.
