S5-R1 Problems with Internetconnectivity

[MGash 0]

Hello there

 

We're using the first version of the S5-Modell in our Company (The one with a Robot-Logo on the Side). Recently like 1-3 months ago the Connection went randomly lost. After checking the Logs, I couldn't identify the problem at first sight, so I contacted the Ultimaker-Support Team.

 

A young Supporter was answering me 3-4 hours after my mail and wanted to see the logs, so I provided him with those. He told me afterward, that the WLAN Card couldn't connect properly, so he sent me the safety instructions to open the bottom Cover of the Printer. I've checked the WLAN card it was looking all fine, what've seen was more of a Firmware issue, since it's not the WLAN Only that is not working, it's also the LAN-RJ45-Port. When I try to turn on the Ethernet port, it just toggles back into off, with no chance to keep it on "online", so it was looking more like a firmware issue to me. I've requested the Supporter for a Recovery Image, so I could restore our company printer. Sadly, the restore was not completed (it started booting into Linux menü, but just exited without any Errorcode etc. I've provided the support a Video of that Problem, and the logs. 

 

Since then we haven't heard anything from Ultimaker support (the last contact was on 17th April). 

 

Maybe someone here in the Community knows how to fix this problem since the support seems like to not care about us anymore. 

 

(Sorry for my grammar, English is not my native language). 

 

Current Firmware Version: 8.2.0

The Image of the provided Image file from Ultimaker was an 8.3.1 Version. 

 

I've asked him to send me the outgoing Buildversion so I can install that and rebuild the Machine state, but no help from the Ultimaker team unfortunately.

 

Thanks for helping!

So from your description I think you probably have bad blocks in your "hard drive".  By hard drive I mean the SSD chip that serves as the drives for the linux computer.

 

The chip automatically detects bad blocks and routes them to new locations but the data in the bad block is lost so you have to re-install the software.

 

Sometimes the bad block is part of the formatting so sometimes you have to reformat one of the 3 partitions.

 

Sometimes the bad block is part of the partition table so you have to repartition everything.

 

Sometimes there are many bad blocks so you have to do the above steps a few times.  Always there are excessive amounts of good blocks because we use maybe 1/4 of the SSD.

 

Most of the firmware installers are "too smart" and won't reformat or repartition unless the size has changed.

 

So I find the easiest way to deal with all this is to install 2 different versions that had different partition sizes.  That way the firmware recovery sees the partition size is different and it has to do a complete reinstall.

 

I have links to a few of these firmware recoveries here: https://gr5.org/unbricking/

 

Okay I just checked the above link and for some reason I don't see very many S5 (any?) recoveries although I know I have some for sure as I've used them for my S5.  I guess I'd try to get one from firmware 4.X and one from 5.X because somewhere in there they changed the partition size.

 

Or you can get an olimex cable and see what's going on step by step.  Described in the unbricking page.  Unfortunately the unbricking page is a mess.  I have edited it maybe 30 times and it gets more confusing each time.  Sorry.  If you have an olimex cable you can repartition it to random partition sizes and then run the latest firmware recovery, it will be forced to repartition.

 

Basically - keep trying firmware recoveries.  Try different ones to force them to repartion and hence also reformat each partition.

 

With the olimex cable you can also run connman (which sets up and controls the wifi and ethernet).

Here are the firmware recoveries I have.  The ones with "R1" should all be for the older S5.  Note the dates.  Pick the oldest and newest (newest supplied from Ultimaker) This is a listing from my website gr5.org so just go to

 

https://gr5.org/insert_image_name_here.img

 

And it should automatically start downloading. Or create the link on a web page and right click and select to download.

 

If there is a newer firmware let me know and I should get off my butt and add it to the below list.  Why UM hides the old firmwares, I don't know.  They are useful.
