Installing linuxcnc on a standard Debian instance is described in the docs here
linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel

PCW, thanks for your answer!Yes, indeed. If I start the PC, my auto internet connection via RTL8111 is online but no websites reachable. eno1 connection to the Mesa card is working but with slower ping. If I switch to a faster ping with "sudo ethtool -C eno1 rx-usecs 0 ", my auto internet connection is online, but I can't reach any website as before. That's only possible if I close the eno1 connection.
I had to install lshw first. The feedback is - not the same irq for both connections.   

I just installed OBS to make a video of that phenomenon.  Maybe I do that tonight. Nope. OBS doesn't recognize my mic. I have to research.

I am shy to install this machine completely new, because I have installed several things and packets up to this point and did not document them. Beginning with libre office, Atril, Firefox, Chrome, Telegram, Geany, Visual Studio (all no problem to install again) and several packages to help with all of these Debian/LCNC problems on my way. Is there any tool or command to show me these not included packages in Debian 12? That would help me a lot.

Thank you for your time and effort...! 

Just like other stepper systems for LinuxCNC the position feedback is from the step generator. For Remora this is the raw step count from the controller board. The LinuxCNC Remora component then calculates the position in mm by using the joint scale value.

Like my earlier comments, the smallest move / positioning accuracy can only be as small as 1 step.

The firmware changes STEP5 to PWM and DIR5 to GPIO
it also sets up the parallel expansion port (P1) to interface
with a standard 5 Axis breakout. This should not make any
operational differences.

Perfect.

Tooldata looks as it should (for a standard 2mm tooltip).

So. Have fun.

Okay!
Thank you for this clarification.
I'm considering changing my control concept rather than the firmware.
The larger Gravograph machines have AC spindle motors anyway, and I can use the analog signal for those as well ...
Would this other firmware only turn STEP5 into a PWM output, or affect other functions and/or pinout of the 7C80 as well?

Thank you for the heads up. I believe I found all of the changes needed to be made.

I have also attached my tool table.

Hi Henk, are you from RSA - I am from Port Elizabeth and am trying for many years to find a solution for my home cnc machine which has old resolvers on it - I want to go LinuxCnc type retro but want to use the old stuff - it's a home hobby not a production machine so I am looking to save where I can - you mention Farrand control converters (is this able to convert analogue to digital signal on resolvers etcetc)
I would appreciate any input + I am aware of SA CnC club but it's in JHB and too far for me to attend lectures

Bad luck for me, changing boot drive did not work.

I tried to install a 'standard' debian-live-12.6.0-amd64 iso and that worked without any problem. Maybe I can use that to 'upgrade' with the LinuxCNC iso or change the installation to be acceptable for LinuxCNC. I don't know yet how to do the first or the second option.

With those settings(attached) i'm nearly there. Sometimes it is spot on, but sometimes like on the screenshot

I can see tool table is good. I changes on g43 g-code. And also adjusts g54 offsets. But there is no change in machine coordinates.
So do I have change xyzac-trt-kins.z-rot-point pin value to according to tool I am using, everytime I change tool. But I think that should not be the case.
"I notice that work coordinate changes according to tool.
But kinamatics is taking machine coordinates so there is problem in RTCP on every tool change.

Aaaaahhh paperless offices ... that never came. That was the promise made by e-mail .
Yes, print screen works on most distros, although XFCE used by LinuxCNC version of Debian did not work but it had screenshot in the main menu somewhere.

Good morning everyone. I am using debian 10 and kernel 4.19.19-rt-amd 64. I noticed that in the repositories there are later versions and I installed the kernel 4.19.27-rt-amd64 which still works well with ethercat. I also noticed that there are kernels 5.10.0-0.deb10.30-rt-amd64. This kernel would work with ethercat. Regarding performance and stability which kernel is better to use?
Thanks

Thank you very much for your help, it worked, I've been trying to get this to work for a while, thank you for your help, I hope I have enough knowledge to be able to reciprocate someday

You are great, thank you very much. I will try to do it tomorrow.
