Hi Rod,

Thank you for the leg up on the development environment. I've spent a chunk of time with it.

Should I use this forum thread to have conversations or would somewhere else be better?

Tom

Hello everyone, 

I have been working the past couple days on getting ethercat working and installed for my first linuxcnc project. I got ethercat working and the slave is showing the master command etc works so that is amazing but now i am stuck with the configuration part. I have not used linuxcnc before and i can't seem to find any well quite basic tutorials on how to set up a single axis and just get it to show in linuxcnc i have tried to make a config using a old tutorial but i just can't seem to figure it out. I am currently using a raspberry pi with Leadshine EL8 driver and the ethercat between these works just dont understand the config part. 

So if there is someone that would be able to help get me started that would be amazing.

Just created a Pull Request for the change required. So hopefully that can be ticked off the list.

If your interest is in kernels and the pi 5, the Linuxcnc builder (for the Pi 5 and 4b)
github.com/LinuxCNC/rpi-img-builder-lcnc
Is a fork of my repo
github.com/rodw-au/rpi-img-builder-lcnc/tree/linuxcnc-2.9.3
Which in turn is a fork of
github.com/pyavitz/rpi-img-builder
with Linuxcnc and the PREEMPT_RT kernel installed

Note the builder cross compiles on a normal PC and builds the official Pi kernel, then wraps Debian around it before installing Linuxcnc and a few other goodies in this script github.com/rodw-au/rpi-img-builder-lcnc/....3/files/userscripts

I got as far as merging the latest upstream code into my  master over Christmas but have not pushed it to my 2.9.3 branch as the default kernel has rolled forward from 6.1 used by Debian Bookwoem to 6.6
It's quite a business finding a Pi kernel commit that agrees with the PREEMPT_RT patch kernel version. 
The latest upstream source now supports the 6.12 kernel so it would be good to build for it as there is no need to patch the kernel anymore
ref: github.com/rodw-au/rpi-img-builder-lcnc/.../patches/userpatches
(but you still need to set the fully preemptible kernel in  menuconfig)
Cornholio has asked in another thread for changes to config.txt to support spi so there is a nice kernel related project here.
