Image V7 with Repetier Server connection to Eduroam

Mr_F_K

Hi everyone,

i am new to this forum so i hope this topic is in the right categorie.
Me and an fellow student are working on an project work to build an xy core 3d printer.
The printer is now built and we are working on the quality, printing speed and connection.
We are using Repetier as firmware and also Repetier Server on an Raspberry Pi 3.
First we installed Debian Jessie as Image and installed the server.
The internet connection was made with the wifi of our university "eduroam" which has an username and password to type in. Also the key management is WPA-EAP.
The problem was that the printer stoped random in the middle of the print when we started the print over the server
After checking the configuration and also the hardware like circuit boards and usb cable there was no solution and we decided to configurate the server new.
Now that we have installed the image V7 with Repetier Server and are trying to get it into the eduroam without any success.

So now my questions.
Does anybody have an idea why the printer stopped random in the middle of a print after starting over the Server?
Can anybody help us that we can integrade our printer in the eduroam wifi?

I have to apologize for my bad english and i appreciate your answers.

Florian

Mr_F_K

Sorry i forgot to mention that the same print worked without any problems when we started the print on SD card

Repetier

WPA-EAP is not the typical wifi type. We have no such system for tests so I can not say what the network manager does if he sees it. The V7 image uses the script

/usr/local/Repetier-Setup/bin/manageWifiAccess to setup the wifi using network manager. Configs from NetworkManager end up in /etc/NetworkManager/system-connections directory. For me the file contains[wifi-security]

key-mgmt=wpa-pskOnce you know how to make connection work with network manager (disable server while testing) you can modify manageWifiAccess especially this part: connectPW) prepareConnect nmcli dev disconnect $WLAN &> /dev/null nmcli connection delete "$P1" &> /dev/null nmcli dev wifi connect "$P1" password "$P2" hidden "$P3" &> /dev/null ret=$? if [ $ret == 0 ] ; then echo "OK" else nmcli connection delete "$P1" &> /dev/null echo "Failed" fi

;;which creates the configuration. You might just need to add a extra parameter for wpa-eap and then you are done.
Stops in the middle are hard to say why. Possible reasons I already saw:1) Uploading while slicer was not finished writing the file.2) Linux closed port for some reason3) Communication errors4) Printer had problems with power crashing usb connectionWe know that you can print for weeks without problems if everything is working stable so you need to find the unstable part. So start logging. If it happens see log for end of print and if there are any hints. Check /var/log/systel to see if linux did something. See /var/lib/Repetier-Server/log/server.log to see if there are any hints in global server log.Make sure Pi is powered good enough. If you have a display connected you see a energy sign in right top if power gets critical - also it might still work. My pi 3 with 3A power connector still shows the sign from time to time, so it is a bit critical. Sometimes a actively powered usb hub between pi and printer also helps especially if printer draws some current from pi. USb specs and pi allow this but if you are on the edge it might be a problem.

Hi,

thanks for your answer.
The WIFI now works, but in order to the stops in the middle of the print we decided to get the Raspberry on the LAN of the network from our university.
After quite a really long time the Print stopped again. The AP was disabled and also we made no connection with the WIFI.
I followed the instructions as you gave me and had a look the log.
Unfortunally we haven´t the knowledge in reading the logs. So perhaps i may ask you to have a look on that?

What logs do you show here? These are not the logs I meant. Looks more like dmesg output. Syslog looks like this;

And server log like this:

You see here you have a more usable timestamp. Also dmesg doe snot log everything only services starting I think.In addition please also provide the time of the error, so I know where to look into the log, not that I can read it better. Each komponent decides how and what to log so no one really can read it fully. You can only hope to make some sense from what you read.

Mr_F_K

Ok, sorry so i missunderstood this. Yes this were the dmesg.
So the print stopping was on Nov 21 at 19:14.
So I took the Server logs from starting the print:

Ok, server log is clear
2017-11-21 19:14:32: error: Reading serial conection failed: End of file. Closing connection.

Linux closed the connection so server close dit as well.

Linux log also shows this
Nov 21 19:14:32 RepetierServer kernel: [31621.614714] usb usb1-port1: disabled by hub (EMI?), re-enabling...EMI happens when the usb mass it not correctly buffered or so. I'm no electrican but talked with one knowing that usb has special termination chips to prevent EMI. So something with that is causing the pi to disable serial causing the stop, but I can't say whos fault this is.Just that it is some electronic problem detected by linux.

Hi,

thanks for replying.

Sorry I have to bother you again.

After trying some things to exclude the reasons for closing the usb port (new SD Card, new Raspberry, new power adapter, new USB cable, measuring the current, etc.). I´ve looked for other reasons, so i looked after the cpu usage of the pi. It´s by 100% after a while (Screenshot following).

After researching the internet i got the information that the RPI3 does overclocking the CPU by nearly 50% of CPU usage. Could it be that the overclocking of the CPU runs the RPI3 unstable and after a while he switches of the USB Ports?

Also I can´t explain why the CPU has an usage of 100% while no printing event operates.

Actually with EMI messages I would more suspect the other side of the usb connection. Especially the cheap chinese arduinos do not always behave as good as you might think. Also I never had emi problems my self, it might be a part where some cents were spend having no termination chip where needed or bad solderings, ... Just a speculation.

100% for server while idle is not normal, but there are some things that can cause longer operations, especially if you have several gcodes. If you change settings in printer that affect speed calculations all gcodes get reparsed. I also have seen browsers with connection problems reconnecting in very fast frequency which can also add a good load on cpu. If you are using our image there is also the x server with a browser accessing the server. If you have no display on pi you should not start it. Edit the last lines of /home/pi/.bashrc to not call the x server and reboot. That reduces load and memory usage at least.

Hi,

ich melde mich nochmal, habe gerade nochmal geschaut und bemerkt dass Ihr ja eine Deutsche Firma seit. :D Manchmal hilft nachlesen.
Ich hoffe es ist in Ordnung, wenn ich auch Deutsch weiterschreibe um Missverständnisse zu vermeiden.

Das Problem tritt leider auch bei einem anderen Drucker mit Arduino auf. Es heißt ja dass 90% aller Probleme 50 cm vor dem PC sitzen bzw. hier vor dem RPI. Leider bin ich komplett ratlos zur Zeit mache ich irgendetwas flasch?

Jetzt kommt mir noch eine andere Frage hinzu. Da wir die Pro Lizenz verwenden und diese jetzt auf 2 RPI installiert haben stellt sich mir die Frage ob die Lizenzen gewertet werden, die gerade in Verwendung sind?

Schöne Grüße

Florian

In mails german is ok, but in forum it only helps if anyone can understand, so we prefer english here.

Licenses activated are counted. In register tab you can any time deactivate a license to free it's counter. In case of severe problems we can also do this for you if that caused you to run out of licenses.

Found this thread:
https://github.com/raspberrypi/linux/issues/897<br/><br/>they have same emi problems. At the end it indicates that a kernel version might cause this problems. So maybe you can check what kernel you have on pi and see if you can update it. Also I did not like the end of the thread giving no real answer what the solution is except kernel version.
