Repetier Server toggles connection state until ...

xBot150xBot150
in Questions & Answers
Hi all,

Setup:
Atmega 2560 + RAMPS 1.4 with Repetier-Firmware 0.92.9 (configured next to vanilla*) connected via USB to a Linux Mint 18.3 (Sylvia)
RepetierServer 0.86.2 Pro installed on Linux, RepetierHost 2.1.2 is also installed via mono-<whatever> on this box
Arduino IDE: 1.8.5 64bit

The weird behavior I see is that...
RepetierServer won't connect to the Atmega (connection state toggles between "red disconnected symbol" and "orange WiFi icon" UNTIL I fire up RepetierHost, click the connect-button -which connects to the same port as RS, /dev/ttyACM0- and disconnect/close RH; after this RS works until I power down everything / press the reset-button on RAMPS or just disconnect the USB-cable.

*) the single change was that I enabled FEATURE_TWO_ZSTEPPER and selected Extruder1 as mirror stepper socket.

... huh ...
I can't figure out what is going on here.

    Very strange, but log seems incomplete so I can not fully analyse. You need to have all communication including ack marked. I see a N11 command not known so I have to assume firmware got the first 10 successfully. Then
    I see

    20:30:27.442: Unknown command:N11 M539 S1
    20:30:29.535: skip 10
    20:31:09.571: Error:expected line 58 got 11
    20:31:09.571: Resend:58
    20:31:09.581: M110 N1

    So why does firmware expect line 58 after line 11. I do not see that it got send, so resending fails. But this again might have to do with hidden log entries making it impossible to debug. COuld be M105 requests which got hidden. Would also mean communication was good in that example except some unknown commands due to using old firmware. But that is no problem as they simply get ignored.

    oh yes, i know but it ain't easy ...

    Is there a way to configure RS to "please log everything that might be related to communications"?

    > "was good in that example except some unknown commands due to using old firmware."
    at least "old firmware" is not possible, after I ran into the issues mentioned above I swapped out my initial "I don't care if this one lets out the blue smoke" with a known-working 2560+RAMPS1.4, downloaded a vanilla firmware (unmodified except enabling FEATURE_TWO_ZSTEPPER) and flashed my hardware with this build.

    -> same difference; the printer-configuration in RS was also "new" (the first one ever on this box); the printer-setup in RH ditto (I still don't understand why the Arduino-IDE refuses to flash /dev/ttyACM0 while RS is running but RH has no problems connecting to the same port (NO, I did NOT configure RH to connect to RS and YES toggled EEPROM_whatever_ from 1 to 2 and vice versa))

    Next: download a really vanilla/unmodified Firmware-Source from the configurator and flash my kit with this build, who knows what will happen; I've seen stranger issues already ;-)

    Summary: Is there a way to configure RS to "please log everything that might be related to communications"?

    all the best & thx!

    Followup:
    flashed my kit with a "as it comes"-Firmware-source from https://www.repetier.com/firmware/v092/ via Arduino-IDE

    removed <printer> from RS (RH -> unmodified)
    "add new Printer" in RS, "ok'd everything"
    -> works

    Shutdown printer-hardware + disconnect USB
    powerUp
    RS: working

    *humm*

    service RepetierServer stop
    Switching Sourcecode to "FEATURE_TWO_ZSTEPPER", using Extruder 1; !NOTHING ELSE!
    Download full source, recompile (Upload via Arduino-IDE as before)
    service RepetierServer start
    RS: working.

    Summary: either I'm veering into the "funny as in crazy, not as in laugh"-area or  the firmware-configurator was out of whack the day before yesterday or ... there was something weird going on with <?> and I just should be prevented to faff around with complicated thingamajigs way above my event-horizon.

    *huh*, color me really really confused.

    CLOSED, Cause: UNKNOWN, possibly sunspots.

    In server frontend in printer context menu is a log page where you can enable logging and also download logs.

    In rare cases you can get multiple reconnects until a printer works. Especially if printers do not reset this can happen if firmware was disconnected in error state(because sending just stopped mit line,...). reconnects happen if we get no answers for a while.
