You should still be able to install it without internet or broken installer but apt will point to the CD only. I think it will get confused in some locales because the installer defaults the mirror and in some countries, this fails.

There is an issue with Debian Live which we use for the installer. Debian moved to using debian deb822 format for sources. This places the sources in /etc/apt/sources.list.d/debian.sources instead of /etc/apt/sources.list

Debian live has not caught up with this change.
so assuming you do get a bootable system, what does
cat /etc/apt/sources.list display? is it just the CD or DVD?

You could create Debian.sources in the folder above that contains
Then delete /etc/apt/sources.list
and then type sudo apt update
 

I think we are working at seperate parts of the code base. I suspect the info you want is probably thrown away after its buffered but I've never looked. You could look at adding your own NML as described here
linuxcnc.org/docs/stable/html/code/code-notes.html
The diagrams are also pertinent

What is visible in real time (motion) is limited to what's in state_tag.h I linked to and its populated in interp_convert.cc.

There is a high level API based on my ideas using gRPC but we've not tested anything. Its limited to what's available in the Python API
github.com/joco-nz/linuxcnc-Headless-UI
This is designed to address the authentication and security constructs the modern connected world demands.

There is also an effort to use a standards based methodology used by Haas and others but I have not been able to discuss it with the author at this stage. But we will schedule that in the short term.

For me it really simple. I rely on my machines for my livelihood. Once I had it working satisfactorily, there was no need for any updates. These controls function exactly the same as the original controls, an update isn't going to change that.

So all is working now....thanks again for your help...I am not sure what INM pins are...would I need another board?

Thanks again!,

what are the differences between the 7i97t_7i74d.bin and the 7i97t_7i74d2.bin
What should i use?
flashing direcly from mesact is a good idea?

I managed to get the machine to power up and boot into LinuxCNC, and I’ve put together a basic configuration just to test it on the bench.

What would you do next? I was planning to load the driver for the 7i74 onto my 7i97T so I could configure communications with the other boards.

I have downloaded and flashed Debian Trixy Linuxcnc from the download page twice now. And every time I try to install, it gets stuck at configuring the sources. I do not think it is a network problem because when I run the live instance, I can browse the internet. Please can someone offer a solution, or tell me where I can download the Bookworm version, which I know works.
Thanks

if I go to V- instead of power supply ground IN2 lights...is that ok? or does it indicate a different problem?

I forgot about that.....no

Does the yellow LED near IN2 operate as expected?

Hi...I used pin that is labeled iN2....and put in Hal as GPIO 002....when I tried to test in Halshow nothing happened....i checked wiring seems ok....I did not know if i am missing something in Hal...I only put  info  in the x axis section...
.
# ---# external input signals...under this part it is blank..


setup home / limit switch signals---
net x-home-sw <=  hm2_7i96s.0.gpio.002.in_not
net x-home-sw <= joint.0.home-sw-in

Thanks for reply!!

TB3 pin Pin 2 would be GPIO 01 (but actually you should be using INM pins, not GPIO)

Pncconf setup would be something like:

 


(invert it using NC switches)

You should also use halshow to verify home switch operation before attemting to home

Ok, that makes sense, I deleted the step config file. Currently I can jog XYZ in the pnc config "test this axis" .
Gmoccapy  jog does not work but shows movement on screen.
Thanks

Had to drop back to V2.7 to get a reasonable jitter number on my old Athlon X2 CPU. (20,000)
 

Very bad idea...
Wheezy with RTAI has low jitter on some motherboards, but today this is time waste only.
This is 32bit Linux, Python 2.7, no realtime ethernet, and old LinuxCNC not compatible with modern, even at configs level, so you get many useless experiences...

Yesterday I installed Debian13.5 with LinuxCNC 2.10 on my Lenovo M725s SFF Ryzen 3 8GB 128GB M.2 NVMe (not newest but still modern), jitter is 20,000 and all works well.
This model has LPT connector at motherboard, but you can buy cheap second hand PCIex to LPT card.
In my opinion, LPT is obsolete, but if exist, you can serve some auxilary signals by this.

There are cheap 7i92 clones on Aliexpress.
I have model similar to original MESA, and chinese version with I/O drivers, both works well.

In my opinion, the future is ethercat and modbus. 
This is more cost and more dificult, but works like in dreams...
