Thanks Rod for chiming in! I bought the Gigabyte GB-BXBT-1900 based on a recommendation you made in another thread. I'll give it a go once the RAM and SSD drive comes in for my Gigabyte GB-BXBT-1900.
Thanks for all your help

I just followed PCW's advice and that was the closest I could find here in Australia. I really wanted a Dual NIC one.

Remember, if it doesn't work, it wasn't me!!!Thanks Rod for chiming in! I bought the Gigabyte GB-BXBT-1900 based on a recommendation you made in another thread.

Hey!!! Hahaha
I'm sure it will work out well. I'm just roaring to get this started already hopefully all my parts may come in today including the Mesa Board.

Here it is, only a few weeks late
www.linuxcnc.org/testing-stretch-rtpreempt/
You probably want the amd64 version on any modern PC.

Now there is a beta version ISO of linuxcnc built on a later version of Debian that includes the preemptive kernel. Hopefully somebody will come along with a link to the beta on buildbot somewhere.

Is this the one that has worked for no one yet or is this a new build?

It's working brilliantly for me. The best latency I have ever had, despite being preempt RT. It is on my testing machine and that means that I have used P-port, EPP-Mesa, Ethernet-Mesa and PCI-Mesa with it, all with great success.

OOoooo, I like the sound of that! I tried installing Mint 18.3 which went well but I'm having trouble getting the kernel loaded after the fact.
I'll reformat and try again with this.
Thank you for posting this Andy to the thread! Very much appreciated

Update
I've installed Debian with the preempt kernel from your link above.
I'm currently working on reducing my latency as it's at about 33,000 Max Jitter and that's with the internal WIFI removed.
In the link provided, I use I see files named .zsync are these updates? similar to a patch for Windows?

I don't actually know what .zsync files are. But the OS (and LinuxCNC) should update automatically (or on-demand from the synaptic package manager)
This is some info from when the ISO was released:
This image is based on the "PREEMPT RT" kernel, which typically
gives latencies good enough for FPGA-based systems, though often the
latency is too high for software encoder and stepgen systems.
Assuming you have a multi-core system, isolating the highest
numbered CPU with isolcpus=# on the kernel commandline may help
latency, just as with RTAI.
Unless you know your computer only supports 32-bit code, I recommend
using the -amd64 image, which works for both AMD and Intel 64-bit
CPUs.
Like the older images, you can either boot live to test your
hardware, or install to the hard disk, from the same iso image.
The Debian image is a "hybrid" iso, which means you can use the same
iso file for a USB stick or a DVD. (The image is bigger than a
traditional CD, so you can't install from regular CD anymore.)
Instructions for writing the image to a USB stick from Windows and
Linux are here:
wiki.linuxcnc.org/cgi-bin/wiki.pl?Hybrid_Iso
**NOTE** the Ubuntu "startup disk creator" and unetbootin do NOT
handle hybrid images. Use the above instructions instead, if you
want to install from USB. To install from DVD you can use any
traditional method to write the iso image.
You can find it at the temporary URL
www.linuxcnc.org/testing-stretch-rtpreempt/
For more notes and for the scripts used to build these images,
see github.com/jepler/stretch-live-build
The github repository has an "issues" section. Please use it only
to file bugs about the image itself, not about bugs in LinuxCNC,
even if the bug in LinuxCNC seems to be specific to Debian Stretch.
(but if you aren't sure, then file it in stretch-live-build and
we'll triage it)
So, it might well be worth trying isolcpus:

That is absolutely perfectly fine for the 7i76e so your job is done! I think thats better than what I'm getting on Mint. Good work!
I played with this and concluded (like PCW) that this is not helpful. The documentation is there just to waste your time....
