Hi bmoo, have you made any headway wiring your spindle?

It clearly states under point 6 that after switching to the battery encoder cable, a reference run must be performed again. After that, you can comment out the lines.
The internal CIA402homecomp should be used for this one-time reference run.

What do your configurations look like?

I have tried both. Setiing it as an XYYZ and as XYZY. copied joint_1 to the end of the ini and named it joint_3, for the XYZY. for the XYYZ i copied Joint_1 and pasted it between Joint_1 and Joint_2. renamed it as Joint_2 and renamed the original Joint_2 to Joint_3. both times with the same error with the limits of A Axis. when i delete the last joint it starts up as normal.

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.

I don't think that would help much without your slave  hardware. Its not just a simple config problem. The remote access is probably the best way.

You might be better making it a XYZY machine, then just copy down an extra joint in  the ini file and copying the joint setup in the hal file to a new joint 3 section which I basically a copy of your existing Y joint (joint 1 ?) Dont forget negative home sequences for your 2 Y joints.

Alternatively, I set up a new XYYZ machine in pncconf/stepconf very roughly ignore scaling etc, then cut and paste the accurate data you have to the right spots.
Anyway that's how I'd do it. I think the first option is probably easier.

I still use only one servo drive, set the position scaling, the maximum velocity of the system and I am experimenting with the homing.
Now I follow you guide about absolute encoders. I uncommented the rows for homing in the .ini and .hal files and added the missing PDOs for homing the .xml file.
By the way in your .ini file you have a homing settings that are not commented and below them you have commented home settings that are said to be only for homing. But if I uncomment them there will be duplicated home settings. Therefore I commented the first batch with home settings and ran LinuxCNC but the missing pins error appeared.

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...

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.
