Hi, Here you can find a few rt-kernels:
drive.google.com/drive/folders/1JglCIPKv...roZcjOvr?usp=sharing

With the 6.1.115 kernel I'm still experimenting a bit to get full gpu acceleration, I think the 6.1.75 is a more safe choice. Then find/create an image from Armbian for example, install the kernel and the dtb of the same kernel version. Check /boot if the symlinks are correct, sometimes when it creates a new initramfs creates a link to the older version, so better to delete or move the other kernel versions to a another place.

With Armbian: when you choose for an image with Debian it's more easy to install LinuxCNC but you probably won't have VPU acceleration (1080p/1440p still works fine though)
With Ubuntu it's more easy to have VPU acceleration, but you'll have to compile LinuxCNC yourself (there's a manual).
With the mainline kernel you should expect that not everything works yet.

So make your choice, find download an image that fits to the kernel you want (Vendor 5.x or 6.x) or mainline. Install the kernel and dtb if it's not exact the same version.

For better latency values isolate the last core (isolcpus=7). With Armbian edit the extraargs line to add the kernel parameter:
sudo nano /boot/armbianEnv.txt
extraargs=cma=256M isolcpus=7
ctrl+x and press y following an enter to save.

In Debian to install linuxcnc:
sudo apt update; sudo apt install linuxcnc-uspace

Hi all
i want to understand is it possible to do machine on linuxcnc as main controller, which will do next things:
Operator put bar of 1.5mm*40mm coper into machine. On received signal ready from button, and going to gcode commands like g01x100 moving bar. After on the command M10 do punch of O-shape hole, next moving to next point g01x250, next triangle punch hole -  M11. Next g01x400, and command M20 cut a piece. 
my question is -
1. somebody already try this king of production?
2. How to do cyclic feeding in long gcode, i mean that i have not the same lengths and different punch map on each bar, i have program for example on 10 bars for repeating.
3. How cnc receive command to return x axis back to zero and let user to put new bat in?
4. What is the maximum length of axis? For example if i will use reel , not bar.
5. I will glad to read some ideas and additional questions about topic)

If the MPG common is +5V, you will need to wire the 7I95T input commons to 5V GND
Also I did not see the actual MPG encoder pins connected. These would need to connect
to 7I95T inputs that support the MPG encoder feature (IN0/IN1,IN2/IN3,IN4/IN5.IN6,IN7)

If you did not want to tie up so many isolated inputs on the 7I95T, another possibility would
be to use the P1 expansion for the MPG (with firmware that supports MPG encoders on P1)

I have looked into this in the past, and concluded that it's not particularly easy.

In your case the answer probably is to send the probed points out of G-code on HAL pins into a python routine that is monitoring them.

For a small set of values you could use one pin per value, for a larger number maybe one pin to send the value and another to indicate which parameter it corresponds to.

What PC?
Are you using a parallel port?
If yes, did you type a ROOT password during installation? This is not good as you have to reinstall and skip the root password.
And reboot the PC when you see this is the error report:
