Hi, i'm new to LinuxCNC with ethercat. I followed the pined Instruction to install ethercat from apt.
I want to use an Beckhoff EK1100 with EL2004 and EL1014. When i try to run my linuxcnc configuration i get following error:
Failed to register PDO entry: No such file or directory
LCEC: master 0 PDO entry registration failed
LCEC: failure, clearing config
LCEC: exiting
LCEC: returning -EINVAL
lcec: rtapi_app_main: Invalid argument (-22)
./ethercat.hal:2: waitpid failed /usr/bin/rtapi_app lcec
./ethercat.hal:2: /usr/bin/rtapi_app exited without becoming ready
./ethercat.hal:2: insmod for lcec failed, returned -1
Shutting down and cleaning up LinuxCNC...
Note: Using POSIX realtime

I created an ethercat.hal which i added to the axis.ini file. I created a ethercat-conf.xml which i added to the ethercat.hal file.

Many thanks in advance, with kind regards
Tobi

Another stupid question from me. When you say:-
"Connect the 7I83 analog out hal pins to the PID outputs"
Is that a physical wire, or something to be written in the hal file?
In hal, make a new config for 7i76E with 7i77, that should get you all the pins for everything, then make a copy and edit the copy to match the Mesa naming and pins:
Stepgens change from 7i76E to 7i95
Encoders change from 7i77 to 7i95
analog out/pid change from 7i77 to 7i83


You say to Change the Stepgens
With  analogue servos and an analogue output card, what stepgen output  entries are required?

Thank you very much! Yes, the OS is Windows 10.

Yeah the log file was OK (though it looked like you did not select the option to make the bit file)

It looks like the bit file error is related to running ISE on Windows 10 or 11 but not selecting compatibility mode
(I always use Linux now so I've never seen that error)

Are you sure the BLDC motor is a NEMA34 frame?  Please use some calipers to measure the bolt pattern and mounting boss (the big locating ring protruding from the flange).  Or measure the mounting plate - either or.

The reason I want you to double-check is that if you are reluctant to make a motor adapter plate you need to make very sure of the existing motor size.
 

I downloaded it and tried to compile but it gives the same error

New update .I can manually create a bit file . But it comes with several warning messages and one error

PS. I loaded the file into the board it seems to work.  The multiplexer pins are visible in the HAL 
If the board works, the error is not important?


 

LinuxCNC understands ending a gcode file with M2 and M30, but it also works with % at the start and end of gcode, so try that, i do not think this resets anything.
Do remove M2 and M30 when using % .

Use PncConf to create a new configuration for your machine with 5i25 and 7i77, save, start that config.
Probably will need more editing and tuning, so have a look here, plenty of info on how to wire, test, and tune:
forum.linuxcnc.org/10-advanced-configura...ning-detailed-how-to

Yes, the machine starts working from the next part of the code until it encounters all axis coordinates. It depends on how the code is generated. If all XYZ coordinates are in one line, then it starts working correctly, exactly from the indicated line. But even the code generated this way does not solve all the problems.
I think a small modification would improve it a lot. Now, when starting from a specific line, the spindle moves simultaneously in the XYZ axes, but if you raised the spindles to a safe height, made the XY movement and only then started executing the code, it would be much safer.

Yes, I tried but again the bit file doesn't compile.
For testing, I removed 2 step generators and there is no change. I am attaching the log file from ISE Design Suite 14.7

I apologize for taking up so much of your time.Thank you very much for the help !

 


PS. I did an experiment. I removed the changes for the shared index. I left only the new changes on the multiplexer inputs. Again the bit file is not created.

Das geht weit zurück zu den Anfängen von LinuxCNC bei NIST und ist bis heute so geblieben (siehe Punkt 1):

lack of md5/sha checksums for iso images is worrying, as it makes a guessing game whever image downloaded is ok, i found an image on torrents, and tha one installed no problem, but sha256sum is different to official download(tried 3 times) so something is wrong image-size not my end.
when running sha256/md5 sums provided on the image the one downloaded from linuxcnc.org consistently returns 4 errors... go figure

funny thing is, image downloaded this morning works fine and sha256sum matches the one i got off torrents yesterday....

 

As far as I know, it doesn't use gettext and qtdragon is not translated.
I guess the only option left is to replace words in the theme file.
You can view the widget names by opening qtdragon.ui in QtDesigner

Das ist blöd.

Habe es das ich nach dem Fräsen ein weiteres Teil versetzt fräse. Dazu muss ich dann den Nullpunkt verschieben. Muss dann immer manuell auf G55 setzen. Sonst null er den G54.

Edit: Im gcode selber steht G55 drin, beim starten funktioniert das. Aber dazwischen das verschieben da muss man dann immer Genau aufpassen das man es nicht vergisst.
