if you are using the image from this link

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.
forum.linuxcnc.org/9-installing-linuxcnc...4-and-raspberry-pi-5

This is for the 4B but you might be able to set the screen resolution in config.txt
pimylifeup.com/raspberry-pi-screen-resolution/
But this file might be in a sub folder

HI
Just wanted to confirm that everything is working
I downloaded and installed the LinuxCNC file for Raspberry Pi 5
followed the stiky written by Rod for the EtherCAT drivers and everything works
my CNC moves like with the PC

 

 

the only thing you can't manage is the display
but it's all great
Thank you!

Hello
I couldn't really continue with setting LinuxCNC up. But I want to probably use a touchscreen to interface with the machine. What size is recommended. The Machine should be a CNC-Lathe in the end. Do you have some recommendations? Also maybe not topic related, but I was wondering if you can set up remora so you can drive the spindle with step/dir?

For Ethercat  installation i followed this video ().After that  I strated test ethercat following his steps while executing lathe.ini file error came. Bellow attached error report.   

gvfs-backends, can't remember if that comes std or not. But lets you connect to other computers via all your usual network filesystems, even sftp if the other machine is running ssh (dont ask about windows on that one), but also smb shares.
Midnight commander, great for when you're on the command line and need a file manager, clone of the old Norton Commander, comes with a pretty good editor, imagine dos EDIT on steroids, can also connect to other Linux machines for transferring files.
Rather than jumping on the latest kernel bandwagon, I suggest looking at those available and see which one gives the best all round latency, yes I know that sounds a bit controversial, but you know sometimes I'm a bit odd. It maybe that the 4 & 5 need different versions. Yeah I know not a real pleasant thing to do, and something difficult if you don't have the hardware at hand. But then again if there's only a poofteenth in it, go with whatever is the latest.
Oh and make sure that's stated very clearly in big stonking red letters where the config.txt and cmdline.txt files are. A lot (maybe just some) people assume that just because they are using a RPi that those 2 files are in a different place......the curious ones look at the sud dir of boot, others just give up and create config.txt where the Raspbian OS has it. And for those that have a bit of knowledge, kinds mention whilst the distro is based on Bookworm, the kernel is a Raspberry Pi kernel and supports overlays. A user the other day was under the impression that because it was a bookworm based distro the kernel didn't support overlays, cause the kernel Debian uses doesn't.
If not the case enable the spi interface by default, and maybe disable blue tooth. I usually disable sound, but that's a personal thing.
And on the release page change that bit that SPI is supported on the RPi5, if that hasn't already been fixed.

Another one from left field, since now with the update eeprom you can install an image directly from the net on the RPi5 and 4 this is not possible for this image. It's pretty cool, boot with blank media in the RPI, it connects to a server, downloads the RPi imager and then writes the image you choose from imager's list. I used this method to install Raspbian directly to a NVME ssd on the 5.


Plus it should know what I want to machine and do the CAD & CAM without any inpout from me. (and no cad & cam needs to be installed, it just knows)

All lscpu gives is info on the cpu, nothing else is reported, and it's really not the info needed.
You haven't given any indication of your error your error, I skipped mind reading & ESP classes at school

Please upload the error Linuxcnc is giving and all the files, ini, hal & xml & any extra files your ini file loads. Screenshots aren't really much help, ever tried using grep to look for a string in a screen shot ? Just a little joke there mate.

Put up the right info and you'll get the help you want.

I've successfully built LinuxCNC by following the instructions in the official documentation. Additionally, I've compiled EtherCAT using the instructions provided on this site.(forum.linuxcnc.org/ethercat/49771-etherc...ce-full-instructions) However, when I reached the final testing step for EtherCAT, I encountered an error while executing a specific .ini file. Here is a screenshot of my sytem configration :

Could you help me troubleshoot this issue?
