      Perhaps @dc42 has other ideas. My money is on the module. Let us know what you find.

        @Phaedrux Will do. Thanks! Also, the Z-Bot printer looks badass. I'm programming this board for what will eventually become a Hypercube CoreXY. For now it's an upgrade for my CR-10S to which I've added linear rails and converting to a 24V system.

            Try removing the Ethernet cable while it is in this loop, then send M122 from YAT and post the result.

              And of course it's not happening anymore... I formatted the SD card instead of just deleting the folders and then reloaded RRF3.2.2. After plugging in through USB, the network issue hasn't popped up yet. Though I haven't put the config_override.g file in the sys folder yet. Let me try that and start up the board again.

                Lol... it happened just as I submitted my previous post.... Here's the M122 log from YAT (scroll through the network address messages for a bit)

                  Your Ethernet state is: Interface state establishingLink, link down
                  Mine (Duet2/Ethernet) is: Interface state active, link 100Mbps full duplex

                  Do you see the connection-state (not traffic) light blinking on the Ethernet connector.

                  Do you have a different Ethernet cable you can try?

                    I tried multiple cables, as that was the first thing I thought of as well. The yellow light is solid on the port when this happened and the green (traffic) light is flickering

                      I do have an 8 port switch between my router and the board, so maybe I'll have to see what's going on there?

                        I changed to a third cable and this time, the board went into the loop and then restarted. Here's the M122 after restart:

                          And it's not connecting to the network anymore. When this happened last time, I had to keep the board turned off for about 10 minutes and then try again and it connected to the network.

                            Do you have any "Cold spray"?
                            Maybe it's your Ethernet interface chip getting too hot?

                              @alankilian I don't, but I have tiny heatsinks that came with my DRV8825 stepper drivers back when I was using RAMPS on my 3d printer. Let me try that.

                                The network isn't connecting right now and the yellow link status light on the ethernet port is blinking periodically.

                                  I reconnected the board after putting on the heatsink on the ethernet interface chip and the network connected. Then it fritzed out 3 minutes later. I'm running out of options here....I've got a replacement Duet Ethernet board on the way. I think I'll test the new board once it arrives and use that if that works... This is beyond frustrating...

                                    When the network isn’t reachable have you already hooked it up with a usb connection and send M552 to check the status of the network module?

                                      @Argo said in Duet 2 Ethernet IP address keeps flashing on display.:

                                      e have you already hooked it up with a usb connection and send M552 to check the status of the network m

                                      Yes, and M552 shows Network is enabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0

                                      This is despite the link status light on the port lit up steadily (amber) and the traffic light (green) flickering.

                                        If then M552 S0 to disable the network and M552 S1 P<ipadress> doesn’t change anything my bet would also be a defective ethernet module.

                                          That's what I think as well. I just downgraded to firmware 2.05.1 and am having the same issue. I'll get a replacement ethernet module for this board and try it out. I do have a Duet Ethernet board in the mail, so that will be for my second printer
