There is something odd with your installation.
I just tried myself to "apt remove ethercat-master ethercat-dkms" followed by "apt install ethercat-master ethercat-dkms" and it worked just fine.
I do not get the "tainted kernel" message.
Can it be that you have compiled the ethercat master yourself at one point? And that the runnning ethercat master is looking for ec_generic in a place where it isn't?
It's a bit of guesswork and searching now.
Can you the command "sudo service ethercat status" and compare the ouput with mine?
 

Edit. Can you also repeat the search for ec_generic, but this time search for ec_master, in the same way?

Edit 2. No need to search. Instead show the output of the command "sudo modinfo ec_master", especially the first filename line.

I would first take a look at:

linuxcnc.org/docs/html/config/ini-homing.html

You can share limit/home switches

It seems to me that rather than a center limit, you would do some math in hal
to assert a fault if the heads get too close to one another.

I would expect that specific support for a dual head gantry machine would have to be done
by direct editing of the hal/ini files, not something that a generic GUI setup can reasonably do.
 

Unfortunately, it still doesn't work. I've since reinstalled the system, but there's no improvement. I don't understand it. The system worked before the reinstallation. I performed the installation according to the instructions. Anything else isn't possible for me anyway, as I'm just a user and don't know enough to try anything myself.

I need assistance setting up my dual-head gantry system in LinuxCNC. My current configuration has:

• Limit switches at both ends of each axis
• An additional center-position switch (to prevent collisions between the two gantry heads)
• No dedicated home switches (just these limit switches)

I'm trying to understand:

1. How to properly configure these limit switches to also function as home switches
2. The correct way to set up homing for this dual-head gantry system
3. How to implement the center-position switch to prevent collisions between heads
4. Proper configuration in MESA CT for this setup

I've reviewed the documentation but am unclear about:

• How to handle the limit switch configuration when there's no dedicated home switch
• The best homing sequence for this dual-head arrangement
• How to implement the center-position switch logic

Could someone experienced with similar setups please advise on:

• The appropriate HAL and INI configurations
• Best practices for homing in this scenario
• Any special considerations for the MESA CT hardware

Thank you in advance for your help!

Well, that was easy.

Figured it out with the help of Hakan! Filled me in on what I was not getting. Working now, or at least far more complete than what I have ever had before.

Thank you!

"Didn't you copy that one over?"

No, as a matter of fact I didn't as up until you mentioned it just now, I did not know that was what I needed to do. But now that I have done it, it looks like it is actually working. At least the gui is now opening and I'm getting signals like endstop and estop triggers being reported as well as mist and flood working.

Thank you for the help. Like I said, I am brand new to LinuxCNC and have something just less of a clue what I'm actually doing. I am considering my self lucky good folks like you have been able to help me make it up as I go along.

Thank you

Thanks,
intel adaptive thermal monitor need set disable? i dont want burn CPU!

lol not offended, you move to fast, i was trying to stay one step ahead. but no you cant just load it as is, but its a very similar config as to what you want in the end. make a copy of your config folder, and replace a bunch of stuff. Specifically the [DISPLAY] section of the config, then there might be some probe related macro files and qtdragon related files. the remora-flexi.hal , dont touch i think. but there are some qtdragon hal files in there

Sorry, didn't mean to offend. Take your time as in the end I will be needing the "thing for easy GUI switching".

Tried it and instantly end up with an error.

flexi: dlopen: /usr/lib/linuxcnc/modules/flexi.so: cannot open shared object file: No such file or directory

I tried it 2 ways by copying the .ini and .hal files into the existing qtdragon config and by copying the entire flexi config file and running it from there and same error.

2.9 will overwrite your 2.8.x installation

If you want to run both, its actually rather difficult because of the different Python versions
required by 2.8.x and 2.9.x

In general its possible to run multiple LinuxCNC versions (say 2.9.4 and 2.10) by having
a normal installed version and a RIP (Run In Place) version but 2.8.x and 2.9.x don't get along.

 

That was expected and just warnings. You can add what it complains about to the ini file later.
But it errors on a missing "postgui_call_list.hal" file
Didn't you copy that one over? All used hal files from the old config need to come over.

ok I understand the philosophy
last year, when I needed to use the RC_gen functionality, maybe you, the ad hoc file was created for me... I thought that the various .pin files had already configured all the features that are listed on the hostmot2 page of linuxcnc
thanks again for your availability

@tommylight,

So, there would not be an error file/log generated I could look for?

Cheers,
