latency and latest linuxcnc

I have a Lenovo M93 that I want to run linuxcnc on. What is acceptable latency for use with a mesa 7i96 card? Preliminary testing below.

You need to be running the PREEMPT_RT kernel for the 7i96

If you follow these instructions, its pretty quick. I know there are other instructions for Mint 20 but I think there were a couple of niggles and I know this one works.

Thanks Rod. I'm installing now...

Is there anything wrong with the Mint 19.2 ISO or is it just because it's 19.2 not 19.3 that no one is recommending it ?

To tell you the truth, I used 19.3 becasue I already had an ISO burnt to USB so I just used that and picked up Tommy's process afterwards.

Oh ok, just thought there might have been an issue with the 19.2 ISO.

I thought with the only hard bit being updating the key from the keyserver, as I forgot what it was on the repo, it was an easier solution. Burn the ISO to USB, boot, install and off you go, Linuxcnc & RT_PREEMPT kernel is installed along with Mint.

I just installed it on my mill a couple of weeks ago, and I really prefer over debian....much to my surprise.

The system I set up with Tommy's shortcut was on my Odroid H2+. It uses a 2GB dual NIC card and its so new there is no driver support in the Linux distros. So I downloaded the driver on Windows, formatted the unused space on the Mint USB stick, and installed that on odroid just by double clicking the driver and gdebi did the rest.

I think my plasma cutter is running on Mint 17.3 and it was really a mission back then compiling the kernel to get preempt_rt. But yes, Mint is the most user friendly distro I've used. Not that I've used many after I found Mint....

Have you used the H2+ in anger yet ?
I'm thinking it maybe an interesting bit of kit.

No not yet. I've not had any quality plasma time for a while... i'd like to make a control box with it and a 7i73 that a monitor mounts to with some controls below somehow. I have it designed in my head. I just have to work out how to design it in Fusion 360 and then make it with my latest plasma accessory.

I spent half an hour checking latency and it will be fine.
