Can the OPI5 be Configured to Run LCNC?

I think wifi is a seperate kernel module so if its been left out, then you should look for the realtek driver and build from source if necessary..
DKMS is definitely supported under armbian.

With my previous test I did a dirty install of the debian packages and had to force install some packages. Now I've removed these and compiled LinuxCNC and it really does work as well as it seemed to be. So it's actually pretty easy to build your own image/kernel with Armbian, you only need to change the kernel config and source, after that you could build it as usually.

If you don't know how to do this yourself I will make an image, but it shall help yourself to make your own so you'll always be able to update and customize it the way you want. I don't recommend to adjust any timer/scheduler related things, adding drivers should be ok, although a bad driver (in use) could increase latency.

The screenshot was while playing a 4k youtube video, 8x glxgears and "stress --cpu8". cpu stress did improve the latency, so made another without.

Till now the only thing it doesn't like is playing a youtube video in the background, but who wants this while machining. It eventually will freeze the video and this also raised the latency up to 30us. This freezing is something I saw with other images too, should be a driver issue. Besides that, you could do about anything without getting latency. 

Sorry a new post, somehow it doesn't show the config I'd uploaded and didn't want to risk to edit my previous message.
Place these files in the right folder to build Armbian with the low latency kernel. Just choose to build the legacy kernel (only option) and it will download the rt version.

No need to be sorry for that, most of us do the same thing not to mess with the editor.

Royka, are you joking to doubt it could be an issue watching a video while the cnc is working? Who is doing this?! 
Funny.. I mean you can use any other device to spend time when the machine is running, right?
Jokes aside, I'm also interested to try this way, Armbian is more flexible and tailored for this board. I will try, in case of issue I will ask your (or Rodw) precious help.
Thanks for now

Me, sometimes!
