I'm using Simens IPC127e. It's a Siemens's computer working on Intel E3940/4GB and Intel i210 network card. This computer was used for industry control, it should working well with linuxcnc. 

I turned off all the turbo mode, C-state,etc. But the latency test shows the jitter is 50-60us. Is it enough for Ethercat control? Is there anything else I need to do with.

Btw, I have no Idea on turn-off the OnBoard Audio, how should I do.

Können Sie bitte einmal ein normales Terminal öffnen — ohne Takshak — und dorteingeben? Startet Firefox dann sauber, liegt der Fehler bei uns und nicht bei Ihrem System: unsere AppImage-Umgebung reicht dann eine eigene Bibliothek an Firefox weiter. Das wäre für uns die wichtigste Information.

You might try measuring at the 7I76U with the plugs removed
though 4.12V sounds OK under load. (its really marginal with no load however)

I can post a program a bit later today that will toggle all the step/dir outputs
slowly for a more complete test.

Vielen Dank für die schnelle Antwort…
Ok da ist was mit Firefox nicht so wie es sein soll…
Ich hatte zwa ein full Upgrade gemacht…..
Aber der Fehler blieb….
Aber erstmal Danke.

Hallo Juergen,

vielen Dank, das Terminal-Protokoll erklärt alles.

Beide Meldungen stammen von appimaged, das in Ihrem Downloads-Ordner liegt — nicht von Takshak. Der Ablauf war:

1. Takshak bittet den Desktop, das Handbuch zu öffnen.
2. Ihr Firefox-ESR stürzt beim Start ab: libatspi.so.0: undefined symbol: g_once_init_leave_pointer, „Couldn't load XPCOM". Das betrifft jede HTML-Datei auf diesem System, nicht nur unsere. Zum Prüfen bitte im Terminal einmal firefox-esr eingeben — der Fehler kommt auch ohne Takshak.
3. Weil Firefox fehlschlägt, reicht der Desktop die Datei an den nächsten Eintrag für text/html weiter, und das ist bei Ihnen appimaged. Dieses meldet dann „Not running on one of the supported Live systems" und scheitert am systemd-Dienst.
Bis Firefox repariert ist: das Handbuch steht auch online auf takshakcam.com in allen sieben Sprachen zur Verfügung.

Zwei Punkte gehen aber auf unsere Kappe, und die beheben wir: Takshak hätte Ihnen melden müssen, dass das Öffnen fehlgeschlagen ist, statt stillzubleiben — und wir werden das Handbuch künftig an einen festen Ort kopieren, statt es aus dem AppImage heraus zu öffnen.

Regards,
Georg

I don't usually clutter up threads like this just to say it looks great, but... looks great! I still need to get the spindle motor cooling shroud finished and installed on my machine... really easy to leave things unfinished once you can make chips, so good on you.

Good morninig PCW;

Checked the voltages at the micro-stepper plugs this morning, all read either 0 v or 4.12 v, nothing in between. Although the high voltage is a bit low, I think it is within operational range. I'm not using an external 5 v supply for the board, though I have one to run my crosshair laser, so I could tap that supply if necessary. All of my dedicated power supplies 5, 12, 24 and 36 v are spot on their output voltages.

Not sure if it is the 7i76U or the 6i25 FPGA, which is configured as a 5i25, in the computer or something else that could be the issue. What is your suggestion at this point?

Hi,

Looking at your .xml file,
you have X, Z, Y, and SPDL, whereas in the .hal file you have X, Y, and Z, and the pins for SPDL are missing.

I believe that in the .hal file,
`loadrt cia402 count=3`

should be
`loadrt cia402 count=4`

Consequently, you need to add
`addf cia402.3.read-all servo-thread`
and
`addf cia402.3.write-all servo-thread`

Then, once LCNC opens, check that the pins in the .hal file match what you see under Machine > HAL Configuration
in the lcec and cia402 sections;
they must match it is easy to misspell pin names.

After the critiques and some changes I have almost completed my controller cabinet. It’s not nearly as Tidy as I would like but I think the airflow should be decent enough to keep it cool. Thank to all the comments and helping a first timer out.

Both linuxcnc and the preempt kernel come from a .iso file which is
linuxcnc_2.9.10-amd64.hybrid.iso
There a .zip file in forum.linuxcnc.org/38-general-linuxcnc-q...ing-program?start=10

which has polygonpocketf.ngc and makeholehere.ngc.

The parts are exceeding the limits set in the linuxcnc .ini file, when I correct this things work as they did on my other system. Sorry for the noise

Yea, I think that our reliance on random folk who come and go to provide builds people rely on is a bit short sighted, perhaps one of the worst aspects of this project. I'd say it's one of the downfalls of "open source", but plenty of other open source projects seem to have it figured out. Who knows, but it's why I just advocate for learning how to build them yourself.

At any rate, I'm glad to hear all is well again! Sorry for any inconvenience I caused. Happy cutting!

I had a similar problem (no errors displayed, only the motors did not want to turn).
I solved it by writing xml for one drive and when it started working, I connected the second one and added it to xml, and that way to the end.
I noticed that Ethercat in Linuxcnc is also sensitive to the order of entries, i.e. it may not work even if everything is fine, but incorrectly arranged...

Hi mwc,

Thank you for your help... The motors are energizing now, not moving but I am now where I wanted to be at 3 days ago. Thank you!

My ethercat_conf.xml was generated using the lece_configgen command. It looked correct... but nothing in the motor controller area was correct. I would have been better off using the instructions from the ethercat github page and just searching the forum here. 

Funny how both the Lichuan driver and the Stepperonline A6 drivers use the same code. They probably use the same (or from the same source) firmware.
