Connection closed by os during print

DanceM

Repetier Server 1.4.1 / 1.4.2 on Rapsbery Pi.
Repetier firmware on Mega 2560 + RAMPS 1.4

For some reason I got my printer disconnected at random during last two weeks. No errors except "Connection closed by os during print" It could be during printing or even saw two times when printer was on idle. It could work fine for a day then error next day. Here while I am writing this it happened again.

I tried various connection settings, bitrates, ping-pong mode, buffer size - all the same.
I replaced power supply (2A, I used it with RS for years but with older RS version) with brand new 3A - did not help.
The last thing for me left to try - different USB cable (testing in progress).
But I think it could be some bug in RS, idk.

I will be glad for any ideas and things to check.
Thank you.

(Also why it does "Starting Time & Date Service..." every minute? Is it okay?)

Repetier

Since it is os closing connection the answer is as you probably guessed in syslog. But from timestamp

Mesg:14:49:34.783: Connection closed by os during print ... trying reconnect for 10 seconds to continue ...

you see your syslog is missing the crucial part where it disconnected, so please check around that timestamp and make sure both use same time zone.

In case you need to check it on system not that syslog rotates dayly so on 22. Sep it is /var/log/syslog.0 eventually already gzipped.

Most important line 1:

usb usb1-port1: disabled by hub (EMI?), re-enabling...

so this is just a hardware issue. As you see a hub that also connects the webcam disabled usb devices and linux assumes EMI (Electro Magnetic Intererence). Aftwerwards it reconnects everything but of course print was stopped. EMI is not really dependent on power. It can be just a cable that is now closer to a usb part or usb ground causing too much change due to induction.

You might want to try connecting the printer to one of the usb 2 ports and see if it gets better.

You should also try the serial connection option to reconnect and continue print after short interruption. Will not prevent the issue as that is hardware related, but tries to continue print without lost of moves. Works on many printers but not all - depends on serial driver if it resets printer or not on reconnect.

I tried to swap the USB ports but it did not help.
Hm.. first USB cable have a ferrite bead on it but it did not help as well :)

The reconnect option did not work, I tried it.

Okay, thank you for information. I will continue the testing and maybe replace Rapsberry Pi with Intel NUC with Linux on it to get more power and stability.

DanceM

It looks like new USB cable (cheaper and longer) solved the problem, there were zero disconnects in three days of various printing tests.
And I moved Repetier-Server to old Intel NUC after all, for better stability.
