Hello bertoldo,
I have no experience with Raspberry Pi. I do with Laptop + Debian 12 RT kernel + LinuxCNC
Here is my files for SCARA with Gmoccapy demo.
You just need to revise EtherCAT "xml" file to meet your real motor servo controller.
Hope you find it helpful.
Tks.
 
 
 

Was going to open a new thread, but thought the image authors might want to get some feedback that might relate to the image.

Installed the 2.9.3 image on a RPi5 and after a few self-inflicted hiccups everything seems OK, including qtpyvcp/probe basic.

Except the touchscreen isn't reconized.  lsusb does't show the touchscreen.

I've got the touchscreen connected through a powered external USB hub, and I've tried every other combination of ports.  The RPi5 seems really picky about what hardware works (or doesn't) on various ports.

Keyboard w/touchpad is fine, as is a usb trackball.  Both of those work through the hub and directly in one of the Pi's ports.

Any ideas on what to do about the touchscreen?  Monitor is one of those generic 15.6 things, and works fine on everything else it's plugged in to.

Thank you very much for this work. I have tried X times to compile kernels without ever succeeding.

thanks again for your work

With this image I was finally able to get ethercat working, with the image for Pi4 that is on the LINUXCNC page it was never possible.

It looks like the release manager has not released the  2.9.3 Image I gave them. Try this one

Hello!

I'm trying too and I'm going to compile it into a single file to make it easier to understand. As soon as I can, I'll make a single folder with a single description and a video from scratch!

I have been able to install ethercat on 3 PCs without any problems, but on a Pi4 it has not been possible, it always gives an error when running the ethercat master command. Has anyone had any success in doing so?

hello, I just did this part:
1- www.linuxcnc.org/iso/rpi-4-debian-bookwo...23-11-17-1731.img.xz
2- forum.linuxcnc.org/ethercat/53785-instal...thercat-repositories and install,
3- forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step ...

ethercat is installed but I haven't been able to communicate with the servo yet... that's what I'm doing now without any major processes.

Raspberry Pi Imager is a user-friendly software by Raspberry Pi Foundation for writing an operating system image to an SD card of Raspberry Pi or eMMC of a Compute Module. The interface includes a step where an image can be selected, and the selection includes third party operating systems as well. Getting LinuxCNC included in this list might help to raise awareness of the fact that LinuxCNC can run on RPi and of the project in general. Also, this can be the preferred and the easiest way of installing the OS for users who are not comfortable using the command line.

To submit LinuxCNC for inclusion, we need to host ready to use RPi images, 40x40 pixel icon and some JSON ( example submission ). When it's all accessible with direct links, someone should fill the form , and wait for approval.

What is the correct order for ethercat to work correctly on the PI4, I have tried all the ways and I always get the error that the EtherCAT0 file does not exist in /dev/

I think I tried Balena Etcher
But yor link above work. You are a Star

I did read some were that the 2 GB RPI 5 has a new die revision so I thought this may have been an issue somehow.

Many thanks. Martin

"Ethercat should be running. If the above command is not found, you have a problem
You can list the slaves if you type
ethercat slaves"
So far I found the servo everything fine... but then it didn't go, from my understanding there is no lcec_conf file...

raspberrypi4b 8 giga, servo ethercat I will add a xml of the drive too 

Thanks. I will try using another cable. Is there any other way to connect the Mesa 7C81 with the Raspberry Pi 4? I have heard that you can connect the Mesa 7C81 using PNCoff, but I don’t understand how. If possible, could you explain it to me?

Hi,

I'm trying to get my Scara to work with Ethercat too. However, so far in 3 months the only progress has been in finding the slave on the Raspberry Pi4 terminal.

How do I configure the LinuxCNC software from scratch so that the Scara robot can run with Ethercat? Could you give me some guidance?

Try also the image from this link:

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

RODW!!!
I redid it again and it worked! It communicated... thank you very much for your help!

I concluded that I needed to install that package first... and then follow the step by step...

Now I'm going to look for how to configure this in Linux CNC since the communication exists now... is there a specific link for me to configure it? I believe I should be at the part where I configure the Linux CNC software now, right?
