Wireshark gives me this:

so it should recieve 192.168.137.22 as ip adress, but i cant ping it nor is it in listed in arp -a.

is this with just the computer and the duet on a switch? can you save and upload the .pcap file somewhere? gofile.io or similar?

(at a glance it looks like the duet isn't sending its mac address as part of the dhcp discovery)

Haffwalker

This is what I get when I connect the Ethernet cable directly to my pc and the duet.

I can't find the Duet's Mac Address anywhere in Wireshark...

I also got a DSO0138 if that helps troubleshooting....I think, that the ethernet module is broken.

A Former User

as laid out earlier, a direct connection isn't the best option as windows takes a while from the link status goes up until its ready with a static ip to start logging and/or serving dhcp.

anyways, still like to have a peak at the whole .pcap for any arp or mdns traffic etc, as well as looking as the ethernet source for the packets etc. but for now it would appear the ethernet module is the culprit, given the firmware isn't corrupted - which is unlikely given the downgrades

@bearer I try to upload to gofile.io, but it doesnt work...I zipped my pcap file into an rar archive and added .txt to the end, to be able to upload it directly...so simply remove .txt and you should have an rar archive.duetethernet.rar.txt

I hope this is allowed (and works).

@Haffwalker I’m still puzzled by why you got an IP address initially. But does increasingly look like a failure of the Ethernet module. How long ago, and where did you buy it? Warranty is 6 months.

Right, I'm guessing you haven't put a static IP address on your computer and the DHCP requests are from the local machine.

The only thing the log actually tells me is that there isn't a single frame that isn't from your computer, i.e no traffic from the Duet. Two possible explanations, either it didn't get a DHCP response before window was ready and stopped trying, or it never started trying. This is why the switch is needed so windows and wireshark is up to speed before the Duet establishes a link status.

I got the Duet Ethernet back in January 2019 for a different project (I did optimize a Deltatower RTA420, because the owner wasn't happy with it's performance, which he now is), but went for the Duet Wifi instead, so the ethernet was sitting under my workbench for over a year now...so no warranty anymore...Well then i probably blow this one up with a bunch of fireworks and get a Duet Wifi instead.
Thanks everyone for your time and help!!!

PS: I currently run three Duet 2 Wifi boards...but wanted to use the Ethernet and get a Maestro as well, to have the full set ^^

PPS: Will also get Duet 3 as soon as I start building a CNC machine...

@Haffwalker You can get just the Ethernet module, if you want. https://www.duet3d.com/DuetEthernet_Module

@droftarts I bought it from makerdise

Just found an old switch...will try tomorrow! Not sure about how to set everything including tftpd up, but will find out eventually.

A Former User

its been a while but from memory

connect computer to switch
set a static ip for your wired network https://www.google.com/search?q=window+static+ip
- ip 10.10.10.1
- netmask 255.255.255.0
configure tfpd64 by clicking the setup button (bottom center of the window)
open the global tab and make sure dhcp is ticked
open the dhcp tab and fill in
- ip pool start address 10.10.10.10
- size of pool 10
- mask 255.255.255.0
- bind dhcp to this address 10.10.10.1
close settings and restart tftpd64.
start wireshark and begin capture
plug in network cable for the duet
power up the duet.
enable the network on the duet with either config file on sd card or by sending M552 S1
pray

you can use whatever private address you like, using 10 is faster to type imho, but techincally its a little dirty to use that netmask with that class of network but hopefully we don't have to go off topic on that any more than i just did...

Haffwalker

I did all of the steps provided, now the green led is blinking less frequently, but still doesn't work.

A Former User

and presumably no packets shown if you enter bootp as a display filter, some arp traffic likely, but doubt its relevant

Haffwalker

neither bootp nor dhcp show up anything.

A Former User

bootp catches both (seems dhcp was added since last time i updated wireshark).

anyways, the horse is sufficiently beaten and still dead.

Haffwalker

@bearer @droftarts thanks for all of your time and help! I highly appreciate it!
I just ordered an ethernet module...will keep you updated, as soon as it arrives!

Haffwalker

and now wait...

Can I hit this thing somewhere with 3,3 or 5v and measure any output? Maybe only one of the smd components blew...or maybe try to talk to the w5500 directly?

Haffwalker

Hi guys,

so I just recieved the new module and what can I say...it works flawlessly now, so the old module was definately broken.

Thanks to all, for your time and help!!!

How can I close the thread?
