You could try an audio switch, or other high performance switch. I think though that the network card suggestion is the better route. Alternately, is there no breakout board to add something like a 7i78 to the 25pin expansion?

At what stage are you?

all you need to do is type
sudo apt-get install linuxcnc-uspace linuxcnc-uspace-dev

This will get you 2.94 which is  a couple of bug fixes behind the current 2.98 version

If you want to get to 2.98 (which is probably not a big issue  for now), follow the directions here
linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel geometry dash breeze

Laptops are not good candidates for linuxCNC because of all the latency inducing features in them but its worth trying. If you do need a better PC, go to 2.98 then. Install with the ISO on the downloads page
linuxcnc.org/downloads/

I have a few installation videos on my @MrRodW YouTube channel
 

Thanks

Download just the publish .exe file from here 

codeberg.org/endian/twincat3_to_lcec_eth.../branch/main/publish

Thats all you need ... Export working config from the TC3, open .exe file, type c -i, hit enter key, drag and drop file to open console, hit enter.... It starts and it will search through root folder of twincat to find real DC configs and it exports the .xml config of master to lcec shape with every startup SDOs which are very important... I did this translator just and only for this feature + some user friendly and free interface too...

Good morning everyone. I would like to do more. I can make an image of my HD and put the image somewhere, made with Clonezilla or other software. Luca, I will contact you, so you can give me a link to support the image. While you have Debian 13, so you can try it on your system. In the meantime, today I will try your patch and try to scale the I/O peripheral, the last one on the bus, and if it still doesn't work, I will change PC.

Hello, 

I dont know, if i am in the right folder, but it seemed like the right one. If not, just move the topic.I have already now managed to get my ethercat servos and i/o running, with 3 motors for XYZ. Now that i have everything running, i want to finally add my second motor on the Y axis for my Gantry setup. Connecting the joints with the ethercat is no problem. But if I go in the ini, add joint_3, set the joints =4 and rewrite the coordinates = X Y Z to = X Y Y Z, and start the machine, i get an error, that my joint_3 min and max limits does not match with the min and max limits on the Axis A. but i dont have an A Axis set up. I guess it wants to merge the Joint_3 with the A Axis, but thats not set up. As far as I understand,  with XYZ it is mapped the following: Joint_0=X Joint_1=Y Joint_2 =Z. Then when i go with XYYZ it should be the following: Joint_0=X Joint_1=Y Joint_2=Y Joint_3=Z. But somehow it is: Joint_0=X Joint_1=Y Joint_2=Z Joint_3=A? Is there somewhere else except the .ini where i need to join the Joints with the axis? what else do i need to change/set up? I started with the sim Axis mm. If i need to post any files, tell me.
I also managed to crash my PC, when starting LCNC. After double clicking the icon, nothing happened, and after like 30s the whole PC froze. After digging around in my changes, i saw that i wanted to change the number of joint from 3 to 4, but forgot to put 4. so it was accidentally left blank, like this: Joints =  
If that helps anyone, here you go.

Thanks

Thanks for your quick reply. It is very possible that I made a mistake somewhere.For some reason, I am unable to create and download the ZIP file using the button in the top right. Is this the correct link? I get an error message whenever I try to generate and download the ZIP. Is this the correct link: codeberg.org/endian/twincat3_to_lcec_eth...ator/src/branch/main Because of that, I used AI assistance to download the data via the terminal instead. There is a high chance that something went wrong during that process.I will redo everything from scratch this evening: download, export, and convert it again, just to make sure nothing is going wrong on my end.I do feel a bit bad about it. There is now such a great configurator that makes the whole process manageable even for beginners, and I still somehow managed to get it wrong. Apparently there is always a dumbest possible user, and in this case, that would be me. :'(

I tried, no much difference, and there should be almost none, the "bug" was more cosmetic, not really hindering OP time, if anything we are talking in the milliseconds range, no human perceivable difference.
OP time is not immediate with DC, can you time how long it takes? If the wait is excessive, there may still be something I have not found.
Would love to get remote access on the debian 10 and debian 13 setups, to compare, get that USB to ethernet adapter please, you are the only one that has both quick and slow OP, and I could compare what the drives and lcec are doing.

Done, thank you.

Looks like JT updated FlexGUI for multiple spindles on GH a few hours ago.

Can't wait to update and have a go at it!

thanks, the EC is a much older version of the drive. these are L7N
So i'm not sure if the settings translate, but its a start.

it's my config here:
no_7/ethercat-conf.xml · Reeye/linuxcnc - 码云 - 开源中国

the servo is L7-EC.

Hello everyone,
I’m working on an unfinished DIY 5-axis CNC router project with a BC head. The machine was originally built by a company but never fully completed, and it has been sitting unused for about 2 years. It never achieved proper simultaneous 5-axis operation.
The current setup is based on Mach3, without TCP/RTCP, so true 5-axis machining is not possible.
Machine configuration:
X, Y, Z + B, C axes
Stepper motors with encoders on all axes
Dual motors on the Y axis (gantry configuration)
BC head driven by stepper motors with gear reduction
Total: 6 motors
I’ve decided to rebuild the control system properly from the ground up using LinuxCNC.
At this stage, I’m trying to define the correct approach:
What is the recommended kinematics setup for a BC head machine?
How is TCP typically implemented in LinuxCNC for this configuration?
Are there example configurations I should study?
Hardware side:
What Mesa configuration would be appropriate for this setup (6 motors, dual Y, encoders)?
Is something like 7i95T sufficient, or would another combination be more suitable?
My goal is to build a stable and correct 5-axis system, based on a proven approach.
Any advice or pointers would be greatly appreciated.
Thanks!

If all you did was autotune, you aren't done.
You need to set the feed forward. Also set the in position error allowance.

What could be happening is that 2 or 3 microns is still within the drives set error, so it just doesn't move.

So I have some L6 and L7 servos coming to evaluate for including with my machines. My understanding these are *mostly* the same as the EL6/EL7 models on their website, just OEM and 1/3 the price.
One notable difference is the 24 bit encoder on the L7.

Anyone set these up in linuxcnc? Issues? Success?
