It might be worth looking into some of the services that maybe running not is not required for a cnc machine, CUPS is one for example.  

With this configuration i will leave like this.
The next issue is i have a 12 inch touchscreen monitor 1024x768 resolution but the touch does not work.
I have another 22 inch touchscreen monitor and it works perfect.
I verify the xinput list and it register the touchscreen as Holtek touch.
I tried to enable the touchscreen with xinput enable 8 (device 8 as the touchscreen) but nothing works.


 

I'm trying to change a drive's home offset via SDO (can't be done via PDO). Executing the command 'ethercat download -p2 -t int32 0x607C 0' returns "SDO transfer aborted with code 0x06010000: unsupported access to an object"

Obviously it doesn't work. Why doesn't it work?

Everything I've found online simply parrots the failure code and doesn't say why.

I have the installed version of linuxcnc on the 2.9.7 version, ive tryed to follow the orders of previes posts but they are to old and much of the links dont work anymore, if i run it from terminal the only output i get is that the plugins for LED, Buttons etc. is missing

well done its working !
I need the distributed clocks working if i want it to be compatible with LinuxCNC ?

I saw that one, that was a new one to me.
How about not solving it, and instead go around it?
Add a PDO say scale as rxpdo? I mean anything useful, you don't need to do anything with it, just a place holder.
Then you don't need that declaration in main.cpp.
I have always had rxpdos so had not encountered that before.
I can try to see what's going on in the code a bit later.

Meister, I think it is how you go from the comfort zone with Twincat to the deep waters in linux.
I read and write eeprom with "ethercat sii_read" and "ethercat sii_write", the EEPROM_generator
gives me directly the eeprom to download in bin format. The tool you refer to can be used
to take an arbitrary xml file and turn into eeprom format for downloading. It's very useful,
one of the tools to keep in the toolchest.

What version of linuxcnc are you using?
Is it an installed version or a run in place version?
What specifically have you tried?
If you run qtdrasigner from a terminal, what does it print?

Thanks Hakan for the inputs.
After not finding any obvious issues using your suggestion, I did what I should have done in the first place and used TwinCAT to test the terminal.
And as it turns out, the terminal seems to be the issue despite being sold as working, I can't get it to output anything with TwinCAT either.
So I will get a new one and try again.

Hello,
I updated the GIT.
I managed to flash my eeprom correctly however with the current I-m stuck in with this compilation issue:[/code]

A little tip for non-Windows users: you don't need TwinCat to read, write, edit or convert .bin/.xml esi files.

Hello
Thank you for pushing me

I took back your project and build with the SPI2, flash you r eeprom and it worked well, im in OP mode in free run.

As I'm a beginner, my goal is to have a working base (basically yours...) and edit in order to adapt my needs.
Now I have the SPI working well, I will try to integrate my encoder from thise base

Apologies for reviving this old topic but found a mistake on the diagram that may generate a lot of frustation to anyone trying to use it.

Pin AI3 is missing, so all other digital input pins from so on are displaced 1 position.

Unfortunatelly even if moderators delete the link in both  #98901  and  #112565  on the forum, the diagram is still appearing as one of the first searchs on search engines. Not sure if OP has a way to change the picture on his cloudfront account.
 

Yeah wifi can be an issue sometimes.
It might be worth looking into some of the services that maybe running not is not required for a cnc machine, CUPS is one for example.

I disable hyperthreading and now it show max 16us and it never froze.
Edit: btw i think i know why it froze.
I had a wifi card put in but now i remove it.
And the latency is better without it.

The missing firmware module can safely be ignored.
The above post can be safely ignored as well.
Tho if it is something you can do and can afford, I would recommend looking at the riocore/LinuxcncRIO project as that can connect via ethernet, is creates step/direction in hardware and as such only requires a servo thread. Another plus being you don't require a RTAI kernel. Just mentioning as this might be worth investigating. The developer is very generous with his time as well and the project is very active.
 

I'l try riocore/LinuxcncRIO later
Last night i did clean install of Debian 12.12
And downloaded :
RTAI Kernel 5.4.258
RTAI modulesernel 5.4.258
LinuxCNC package for RTAI kernel 5.4.258

Now when installed the kernel the message with i915 did not show up.
After a night of latency-test the numbers are ok.
 
Hyper threading is active that why it say 2 cores.

I missed the "shared home and limit" option.
Thank you for pointing that out!
