Thanks. I will try to adopt them. As far as i have seen, the example file is for 3drives, and i right now only have one. The pid and vid i will also have to fill out.
Starting this project, I knew there will be a pretty steep learning curve. But i like challenges. I also have a Mesa Card on its way. Would that be easier to start with?

It's easier to start with a Mesa card for sure.
You have the pncconf utility that will give you a working configuration.
Once you have the Mesa config working, it's not that hard to
replace the motion part with EtherCAT. Cut and paste, though.

Er, no. It’s not that simple; LinuxCNC isn’t plug-and-play. If you don’t have any prior knowledge, you should put the A6 aside for now and start with simple stepper motors. You’ll first need to learn how the system works and what each component does. With EtherCAT, you’re moving beyond the hobbyist level, and even professionals sometimes find it frustrating.

I only broke 4 mice from throwing them in anger... its fiiiinnnee.

In seriousness though, I find its less about beginner vs expert in CNC stuff, and more about if you are well versed in linux usage. Most of my troubles setting up were because the instructions just assume you know everything about linux already and leave a lot of critical details out. I am working with one of my customers to trying an make a true step by step guide.

If you do know "nothing", step and direction with a mesa card is generally pretty safe cause its mostly done by a wizard. You aren't mucking in the terminal or doing much editing in HAL.

(also important to note ethercat in linuxcnc has some quirks too, its not quite "final" in my opinion)

Well, i tried just copying the files and the call to the halfile in axis_mm.ini and now i get the error trivkins already exist. Tried removing the x axis parts in core_sim.hal, and i cant save it, as it has root as owner. How do i Bypass this?
