Mesa 7i95

I changed the mesa card connection to the realtek and now it seems to work!!
Maybe is to early for say ....but I hope!!! I let it work until tomorrow..will let you know about!
thankyou!!!!!

Hi,
It works! the problem was the Marvell internal network card! Using the realtek card everything works correctly!

PCW and tommylight: if you come in the north of Italy (Val di Non) I will offer you a dinner!
Thank you for help

Will the 7i95 ever be officially supported in LCNC 2.8?

There's no technical reason why the hm2 driver changes could not be backported to 2.8 I'll look into this.

Hello guys,

I'm new to this forum and also to linuxCNC. I hope somebody here can help me out with my project. I have a rather multi functional CNC here with a broken controller. A new controller was way more expensive than a 7I95 board, so i thought i might give it a try. Since i have a lot of I/O with tool changers etc. the 7I95 board seemed a good choice to me. Sadly i didn't knew it wasn't supported out of the box with linuxCNC. My board is still on it's way but i'm already messing around with pncconf. I already have the 2.9 master branch installed.
I guess i have to start with the 7i96 and try to get most of my configurations fixed by pncconf? Or is there another way to get the 7I95 to work? The 7I96 has a different pin layout than the 7I95 so i don't know how i should arrange my setup in pncconf? Since my CNC uses a combination of belt and rack and pinion i want to set the steps/mm by the test/tune axis option. How can i get this to work with the 7I95 card? For now i just want a 3 axis stepper drive and 3 endstop configuration. If i can get this to work i guess i should be able to adapt the hal file to my needs. I hope somebody can help me out here! Thanks to you all and stay safe!

Most of the setup between a 7I95 and 7I96 will be common, the main difference is the
isolated input pin names. I dont think pncconfs test/tune option will work but you can
adjust scaling live with the calibrate menu once LinuxCNC is running

So what should i do? Just use pncconf to generate the hal file with the 7I96 board with my 3 step gens 3 endstops and start/stop signal. When it's generated i just have to change the board name from 7I96 to 7I95 or are there still other things i should change in the hal file before i can get this to work? The input pins are the next problem to solve haha. I guess i should just use the naming defined in the manual for the 7I95 card?

Yes, just use pncconf to generate a starting hal/ini file set

At the minimum you will need to change the card name and the isolated input
names

7I95 isolated inputs 00..23 (NN=00..23) are named:

hm2_7i95.0.inm.00.input-NN
and
hm2_7i95.0.inm.00.input-NN-not

If it helps, I went through similar when I bought my first 7i76e some years ago when pncconf did not support it. I copied someone else's hal file and then just edited everything by hand. (at least you can create your sample!

I used halshow a lot to read the pin names and just did one bit at a time. If I broke something, I would comment out that line and so it would open linuxcnc and read the right pin name from halshow, then went back and fixed it. Always run linuxcnc from the command prompt as the errors will be displayed where you can see them .

With geany text editor you can have you r hal and ini files poen and just save them and rerun linuxcnc.
