Network connection Connection via a network lead is new area for me, however I have been doing a little exploring from Windows 7. From "Network Connections _> Local area Connection I find it reports the IP address as 169:254:100:212 and subnet mask as 255:255:0:0 Running diagnose eventually returns an error message "Local Area Connection" doesn't have a valid IP configuration" I have tried editing the entries to match the Duet microSD setting but always get the same error message. I'm not expecting an answer to this, but just thought I would share my findings. Note these are using a cross over cable. https://reprap.org/forum/read.php?340,280194,280194#msg-280194 Fri, 16 Oct 2026 04:17:16 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?340,280194,285819#msg-285819 Re: Network connection https://reprap.org/forum/read.php?340,280194,285819#msg-285819

I just tested my replacement board with the 5 volt derived from the PSU. The webinterface now seems to work ok. The control page appears for a short while, then the login page. But this time I can log in and see the control and the other pages. I did not print or made other tests yet.

I had first to solder a three pin header to the pads marked J20 on the Duet board. For getting the 5 volt supply to work both left pins of the power pcb (K1) had to be connected to GND on J20 on the Duet board and the right pin of the three header row (K1, power pcb) to 5V_IN of J20.

So it's obvious the step-down regulator (A4403) is again not working on my replacement board. Resistors (R60, R62) are soldered as silkscreen indicates...

Changing range to same as router .0. instead of .1. doesn't change anything. I still can see the new IP but can't ping it.
Same if I play with the netmask. Basically, router will see any the board with any IP I set on the SD card but will not be able to ping.
I give up now. Will see if anything improves when I pick the new board early January.]]> arnaud31 Ormerod Sat, 28 Dec 2013 09:09:09 -0500 https://reprap.org/forum/read.php?340,280194,285557#msg-285557 Re: Network connection https://reprap.org/forum/read.php?340,280194,285557#msg-285557
@gampie: The instructions cover the jumper locations; on this page for the ATX power PCB: [www.reprappro.com] and then the jumper on JP9 on the Duet is covered in the commissioning instructions: [www.reprappro.com]
"Now connect the ATX power supply unit.
The PSU will supply the motors and heaters with 12V, while the logic is supplied with 5V. Make sure that there is a jumper on the JP9 (5V_EN) pins. With no USB lead connected, a light should turn on on the board, near the reset button."

The commissioning instructions do need a few pictures; it's a bit of a wall-of-text, and easy to miss bits out.

The silkscreen on the Duet does a pretty good job of explaining what each pin does. The source files are available here, if you want to investigate further: [github.com]

It looks like even my replacement board doesn't provide 5V power - I should have checked that! (I was so sure in the first place the replacement would work...).

So now it's obviously for me, why the network doesn't work for me - looks like I have to replace the board again :(
Resistors are mounted the right way, jumper (JP9) is set.
I will do some tests with a 5V direct supply (soldering header, JP10 enabled) as mentioned by Ian. Maybe that helps and brings things straight.

1. Check that there is a jumper across the "5V EN" pins on the Duet board. See attached photo. If there isn't, DO NOT add a jumper in this position until you have done the next check, or you risk destroying some components on the board.

2. Check that components R60 and R62 next to that jumper are the right way round as on the photo, i.e. at right angles to capacitor C5, not parallel to it (they should be on your kit #, but check anyway).

I suggest you wait for an official response from Ian before changing anything. In the meantime, if you have a spare USB wall wart or phone charger, use that to provide the 5V power.]]> dc42 Ormerod Fri, 27 Dec 2013 18:12:53 -0500 https://reprap.org/forum/read.php?340,280194,285442#msg-285442 Re: Network connection https://reprap.org/forum/read.php?340,280194,285442#msg-285442 My network connection works, but only if powered by the micro USB (my laptop).
I searched this forum and found out that there is a solution, Something about wiring from the 12V supply.
I cannot find a good guide with pictures like the build guide that help me tot to solve this issue.
I don't want to solder anything on the Duet, like putting capacitors or things like that. Just like the build instructions crimp some wires, connect it, or put a jumper somewhere is OK.
Otherwise I think there are still serious issues in the design of the board.]]> gampie Ormerod Fri, 27 Dec 2013 17:34:10 -0500 https://reprap.org/forum/read.php?340,280194,285289#msg-285289 Re: Network connection https://reprap.org/forum/read.php?340,280194,285289#msg-285289

When I connect via Ethernet, I always see the control page briefly before the login page appears. So I think this is normal behaviour.
Just to confirm, I always see the controls for half a second before it switches to the login page. Logging in is still hit & miss, but hit enough to print off my first few objects yestderday!

Yes, you're right, this does seem to be the correct behaviour. What isn't is if it goes straight to the web interface. This, I think, means the SD card did not supply config.g, or it couldn't find it, but it is finding the www folder on the SD card, to show the web interface.

This might work if you netmask is 255.255.0.0 but not if it is 255.255.255.0
Set the printer ip address to 192.168.0.200 and netmask to (I expect) 255.255.255.0

My setup is the following:

- Ormerod powered by supply (my board works without USB);
- SD card in with I hope all relevant files downloaded from website (SD image);
- Ormerod connect to router (Virgin Media) via a cable;
- Laptop wirelessly connected to router;

From laptop I can access router interface (192.168.0.1) and check who is connected to router;

Ormerod appears with IP 192.168.1.14 and MAC address (see slide one of attachment);
From the advanced settings option of my router I can ping IPs but when I ping the Ormerod (that the router can see) it doesn't work (see slide two of attachment);

So router see Ormerod, ethernet green LED is working but I can ping Ormerod and can't connect to it through Chrome either;

Any idea?]]> arnaud31 Ormerod Thu, 26 Dec 2013 16:18:31 -0500 https://reprap.org/forum/read.php?340,280194,284993#msg-284993 Re: Network connection https://reprap.org/forum/read.php?340,280194,284993#msg-284993 dc42 Ormerod Thu, 26 Dec 2013 15:21:34 -0500 https://reprap.org/forum/read.php?340,280194,284932#msg-284932 Re: Network connection https://reprap.org/forum/read.php?340,280194,284932#msg-284932
1. Check 5V voltage, as described in the first couple of paragraphs of the commissioning instructions. You will get drop-outs if the 5V voltage is marginal (4.5V). Either find a good USB power source, or power the board from the 12V supply (if you haven't got one of the first 220 kits).
2. Check the SD card is working reliably. You won't get a reliable connection to the web interface without it, because the web interface files are stored on the SD card (for easy update). Use a different card if the supplied one seems unreliable.
3. Plug in ethernet, check you get a green light - this is a hardware connection.
4. Ping the ethernet port, to check the hardware it working.
5. Update the config.g with your network settings.
6. When you connect, you should get the login page, not go straight into the controls. I think if you go straight into the controls, there is a problem with reading the network settings, or the web interface from the SD card. This will be subject to a lot of improvements in the coming months, but basic communication is the first hurdle.

It is possible your board hasn't been soldered well; it seems the mini USB connector and SD card are the most likely to develop a fault. We will replace any card under warranty, but would like defective cards returned to us, so we can improve manufacturing.

With such a new board, and quite a number of factors that can potentially cause issues, it's hard for us to see a common thread that causes problems, and networking is perhaps the most problematic to troubleshoot, as it relies on all the other parts functioning correctly. We are trying to address issues as they arise.

When I try to access the webinterface page I can see control page for a short time, but then it redirects to the login page and loads forever. After that I can't even connect to the IP.

I would have suspected that it's a power-up rise-time issue but for the fact that pressing the reset button didn't solve it. Still, it seems to me to be something to do with 5V quality in my case.

SD card is working as I have been printed approx. 400grs (120metres) of parts, mostly on SD card, before my USD socket snapped;
All 3 folders are on the card indeed and I confirm to be pinging the Duet and nothing else.
I am indeed using Chrome (on Linux Mint - same as Ubuntu) and I have just checked that JS is enabled.

So it must be the firmware but I cannot updated since I cannot connect to board.

If you can ping it, then the Ethernet connection must be working and you should be able to connect. A few suggestions:

- Have you checked that you really are pinging the Duet, i.e. the ping fails if you disconnect the cable or turn the Duet off?
- Are you using Chrome, with JavaScript enabled?
- Are you certain that the Duet is reading the SD card OK? [If you are using the SD card shipped with the kit, change it for a better one]
- Did you also copy all 3 folders in the SD image folder to the SD card when you updated the firmware?
