At the point of "Test ethercat with linuxcnc " i am facing issues like "lFound file(REL): ./ethercat.hal
lcec: dlopen: libethercat.so.1: cannot open shared object file: No such file or directory"
But path my directory (path=$PATH:/usr/local/lib)

Yes I'm pretty sure they are analog input driven.

I'm planning on using the 7i97T with another card for more I/O. Was planning on using a 7i84, but I can't find them anywhere in stock. I need 20 sourcing outputs and 25 sinking inputs in total.

I could use some relais to convert the sinking outputs of the 7i84D to sourcing ones, but that seems unnecesary complicated. Other option would be the 7IA0 or the 7i77 but they are both 150€ more expensive.

For the controller I'll probably use a Raspberry PI 5.

My LC2.9.2 is running nicely on a Raspberry Pi 4B with AXIS.
But, it will not accept multiple MDI commands.
I used to be able to do this on the earlier LC2.8.4.

Spent some time checking ini and HAL configurations, and Forum searching, but no joy.

Suggestions ?

If your problem is to only view LinuxCNC on Windows and you are not interested in the desktop of the Linux machine I recommend using an X-Terminal like MobaXterm

Alternatively you can see how this new feature works

One drawback for a terminal is that probably you are not be able to connect to a running process (in this case linuxcnc) but you have to start it inside the terminal. For us that have configuration to start linuxcnc automatically on boot this won't work.

Raspi connect is something I would not use because of the need for cloud connection.
I advice using only services using local network for machine control.

Thank you so much ,that's very helpful.

I use tightvnc, never had any issues. Windows 10, so that may be the reason for black screen.
Just follow some guide to setup vnc on debian. And never operate the machine remotely.
Vnc is only useful to sometimes check gcode without going to the garage...

if you are using the image from this link

forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=40#303752

maybe they should already be installed.

I've never used Ethercat so I've never had this problem.

However you can see at this link

Hello everyone, after the resignation of my very esteemed colleague, I need to set up the software on a functional system using a LinuxCNC mesa7i76e card with a Raspberry Pi 4. When the SD card got corrupted, I had to reinstall the software, but I have no knowledge about this subject. I downloaded the LinuxCNC 2.8.0-pi4 image file from the internet and wrote it to the SD card. The system runs, but I can't establish communication with the Mesa card during the setup. If anyone can provide support on this matter, I would appreciate it. Thank you in advance and have a good day.

I wouldn’t trust Windows anything to pour a glass of water.
But if you must, there has been a changer in one of the vnc apps, can’t remember which, which doesn’t allow a user to login remotely as well as locally. Linuxcnc is just Debian under the hood, nothing special other than Linuxcnc being installed. So any tutorials for Debian bookworm on vnc will be fine (the platform won’t matter). Since the linuxcnc images aren’t based on the Raspbian images any tutorials for the RPI5 using the Raspbian images will not be
what you want.
But before you do anything ensure you have a physical estop if you insist on vnc, cos if you lose your connection you’ve lost control of the machine.

Hi, I have tried installing tightvnc and realvnc but iam unable to access the remote desktop of linuxcnc in my windows system. I have installled tightvnc sofware in windows 11 iam getting blank screen. Can anybody can tell me the VNC which supports Linuxcnc ?.

Hey,elovalvo,I've installed your image in my rasppi5 machine,but met a problem while I installed the linuxcnc-ethercat ,I cant run "sudo apt install -y linux-headers-$(uname -r) ethercat-master linuxcnc-ethercat",because I cant find the right kernel version of header,could you offered that ? Thank you

I have a Mesa 7c81 card that would like to use in the servo mode. I have not been able to get the LinuxCNC Pncconf to complete its configuration to complete. It gets stuck with a python error. I edited the python code to fix some of the errors. I would also prefer to use the raspberry 5 and the 7c81 needs the spi to use the 7c81. For some reason the pi 5 only uses 1 screen. If it’s helpful I have time to test running your updates to provide feedback if you don’t have a full HW test bed to help test the code fixes.

yes, if you use pre-developed image, Everything work well. But Actually i am trying build linuxcnc from source file and ethercat too, there only i am facing issue

Have a read thru this thread.
