Setup network via USB

[dsloan 0]

Hi,

I'm having trouble enabling the Ethernet connectivity on my Ultimaker S5.

 

I've recently upgraded the firmware to version 6.2.0.

 

I'm using the 'Setup network via USB' method. The contents of my ultimaker_network.config file are shown here:

 

 

The file seems to be read correctly because the machine name updates. But the status is always 'not connected' and it is not pingable.

 

 

There are limited tools to trouble shoot this problem. Can someone offer some advice on steps I can take?

 

PS - WIFI connectivity is not an option.

Suspecting that there might be an error in my ultimaker_network.config, I have since tried a simpler version:

 

 

I removed everything except the specify that the type is Ethernet (above).

 

The 'Connection type' remains the same; Unknown.

 

 

Does the Ethernet port need to be enabled somehow?

Not certain if ping works unless the printer is in developer mode.  I'd put the printer into developer mode - at least for testing purposes.  In developer mode the printer displays it's ip address at the top of the main screen on the S5 and I think ping is enabled.

 

Ping may be disabled.  It might be that you had the printer in developer mode before the upgrade and the upgrade turned that off by default?  I don't know.

 

The thing is - I'm not sure what "status" and "connection type" mean exactly but I suspect "connection type" should read "ethernet".

 

Is this the exact same file as before the firmware update?

 

Some ideas:

 

I'd contact your reseller.  It's possible there is a known issue with this version of firmware (6.2) and having the ethernet stop working

 

If it were me I'd get the olimex-serial-cable-F and connect directly to the linux console so I can go in there with conman and expleriment more directly (like trying to ping outward).  There are deadly voltages in the S5 if you remove the cover but personally I don't have a problem with that (e.g. I don't have a cat which could easily rub up against that power supply if I had the cover off and cables going into it and I'm careful not to touch anything when power is on).

 

I seem to remember that the S5 firmware has some kind of firewall now?  I am not up to your version of firmware.  Maybe there is a problem with this firewall?  Try turning off the firewall (as an experiment):

Do you have air handler or material station?  If so I'd try to stick with latest firmware.  If not I'd go back to an older version.  Much older.  Your reseller can help you with that - since ethernet is down you can copy it onto a usb flash drive and upgrade that way.  Or if you are really desperate you can use the restoration procedure that uses a microSD drive.

 

There shouldn't be any need to hide some of the IP addresses because 10.X.X.X addresses are all private.  They don't exist on The Internet.  They are only on private local area networks which means I can't connect to those addresses unless I am already in your company network.

 

Did you read any of this stuff?

Thanks for the feedback, gr5. It helped me troubleshoot further, but it looks like the IP address is not getting set properly. Here are the steps I took:

 

I retried the following ultimaker_network.config file:

 

 

...ensured that the Firewall is off:

 

...and after putting the Ultimaker into developer mode, the IP address appears to be blank

I've just upgraded to Firmware 6.4.0

 

 

No luck. The IP address is still empty and shows as ---.---.---.---

I've also tried turning Wi-Fi off in the ultimaker_network.config file.

 

Still blank IP address:

Can anyone suggest something else I can try to troubleshoot?

Will the log files show anything about the IP address?

I have some questions:

 

1. Was it working before the upgrade to 6.2?
2. Have you checked the Ethernet cable itself? Maybe you can connect something else on the cable to see if the infrastructure and cable is working.
3. Have you the possibility to check the other side (router/switch) to check if there is actually a link between the printer and the switch? Not sure if the ethernet port on the printer has a led, but you can check it.
4. Why do you need the config file, is there no DHCP on your network?

[Smithy 1,146]

One more idea:

There is often a problem with text files from windows, because there is a mismatch with CR+LF between Windows and Linux. 

 

Try the attached file, which should be ok and which has the settings you posted before. You need to unzip it, because I cannot upload the file otherwise.

Thanks for your input, Smithy. I've answered your questions below:

 

1. Has it working before the upgrade to 6.2?

Never

 

2. Have you checked the Ethernet cable itself? Maybe you can connect something else on the cable to see if the infrastructure and cable is working.

I have checked it with a PC, and the cable works.

 

3. Have you the possibility to check the other side (router/switch) to check if there is actually a link between the printer and the switch? Not sure if the ethernet port on the printer has a led, but you can check it.

I've checked this, and it works.

 

4. Why do you need the config file, is there no DHCP on your network?

There is, but the result is the same. The IP address is blank:  ---.---.---.---

Thanks! I'll try it tonight. However, I don't believe that is the issue since the "Machine Name" in that file is read correctly. I change it every time, and the displayed name updates accordingly.

[Smithy 1,146]

So your printer was never connected successful to a network right?

 

hmm, du you have the possibility to connect it via wifi just to test if that would work? (I know you don't want it on wifi but would be interesting to see if the problem is just on ethernet or general)

 

Have you ever tried to ping the configured IP address? I mean maybe there is just a bug/problem with showing the address in the dev screen. Ping should always work, also without dev mode.

 

Is this a new printer?

I just loaded the ultimaker_network.config from the zip file you provided. Same problem...a blank IP address.

 

do you have the possibility to connect it via wifi just to test if that would work?

Our corporate IT group will not allow the printer on the WiFi. I have however, been successful with using the "Start WiFi setup" wizard with my cell phone. So I am able to create a hotspot.

 

Have you ever tried to ping the configured IP address?

Yes, I have...and it doesn't respond. Just tried it again now:

 

 

Is this a new printer?

It's about 2 years old.

 

[Smithy 1,146]

Hmmm???

 

My last idea, have you already tried a factory reset? If not, unload the spools and do it, maybe it helps.

[dsloan 0]

I used the 'Reset all printer settings'

 

Waited for the reset, then attempted to turn on Ethernet...it automatically switched off again.

 

I then tried to use the ''Setup network via USB"... no luck. The IP address is still empty:

 

[Smithy 1,146]

Very strange, but I am sorry, I am out of ideas.

I would contact your reseller to get more support or and replacement of the board.

[dsloan 0]

OK, this has been solved, finally! 

 

In short, the internal Ethernet cable was faulty. If bypass I plug the internal cable and connect directly to the board inside,  it works fine.  (opening the bottom panel of the printer is not advised due to electrical safety reasons)

 

Originally I thought this was a software problem since the IP address appeared blank even after configuring the static network settings. This is normal. The IP address appears blank until a valid network connection is found. Once on the network, the static IP address is shown on the display.

Thanks for the feedback and I am glad it works now!
