7i95 - How to finish? was created by JackW327
I'm not sure what to do to finish this 7i95 config. I can ping it. Mesaflash talks to it. It's at 10.10.10.10 and I don't need to change it.

I've got the current 2.9 dev version installed of Linuxcnc. I ran Pncconf and selected the 7i96. Then I went into the [my-machine].hal file and just did a search & replace for 7i96 for 7i95 as a start. I then ran Linuxcnc from the desktop icon created by Pncconf. It works I guess. The watchdog LED on the board turns off. I appear to have packet traffic by the LED on the RJ45. I assume at this time the ports are wrong. 

I see the instructions to make something in one of the threads, here . I may have missed it but I'm not sure what that is? Is this still current advice? Is it a hostmot2 for the 7i95? Something else? I assume it's not Linuxcnc itself.

Really, really, sorry.I think what throws me off about this entire process is that everything is all over the place. It's very difficult to get a view of what needs to be done in a direct A to B manner. I don't usually have so much trouble with these things, but, here I am.

Once you install Linuxcnc all the drivers are there for the Mesa cards.
Pcnconf will load all the modules you require.
Sometimes some fine tuning is required, but mostly things “just work”.
If you start your Linuxcnc config and doesn’t exit due to an error the config is good.
All that should be required is to hook up your stepper/servo drivers, and any other hardware and off you go.
What do you mean by “finish your config” ?
Apart from how the steppers connect there are that many variations that it’s hard to have an A to B reference. Some users have limit and home switches, some don’t. Some have spindle control and some don’t and there is a ton of ways to hook a spindle up. Some users hook up a pendant and this can go many many ways.
Then there’s Estop switches, switches you can hook up to work with the GUI.
And there is also several guis you can use.
So what is your end game ?
Just do one bit at a time, say add your external estop, then decide what to do next.
Keep backups of your Hal & ini files just in case things go pear shaped.
If need be comment the files so you know what you were thinking 6 months later.
Another problem we have is many ask questions, but very few do a write up after having got their answers. The community needs help, especially from those that having a first go. That way we all benefit.

I don't actually know what I mean by 'finish the config" unfortunately. There are several loose ends that don't seem to be tied off.

The 7i95 does not show up in Pncconf so this is all a hack. I do see code addressing it under hostmot2 on github.

Was the .hal file all I had to tweak? (BTW Linuxcnc did error out before I did that)

Then there is / was a good bit of advice in the thread I referenced above I don't understand very well. The mesa files referenced at one point in the thread are not there anymore ...

I really don't know what config files are used and/or where they all are. So it's hard for me to know what to check.

Well, I guess this week I'll hook up a gecko, a test motor & encoder & see what breaks.

Any advice would be helpful. Happy to post back what I've done here once I get there.

your config files are

/home/yourusername/linuxcnc/configs/nameofyourconfig/

If YOU don't know what you mean by your question, it's one that is going to be hard to answer.

You're on the 2.9 (master) branch so you should be good to go (if you installed this via the package manager there shouldn't be any need to build from source).

Ok let's address the errors you got first before going any further.
Can you start up Linuxcnc with your config and when you get your error please read the error log, you may not understand too much, but it does give instructions on where to go next.
Reading the docs, yes reading the docs, is a good start.
If you don't understand advice how can you conclude that it is good advice, good advice is advice you understand.
If you don't understand something start asking a question about something specific you don't understand. Unless we know what you don't understand it's really really hard to help.

Just trying to be honest and open with everyone about where I'm at. I could fake it but that does not help anyone. I do appreciate the tips. 

I may have answered my own question. I captured the below from the CLI startup. This looks like Linuxcnc is talking to the board and loading the correct config. I checked the pins reported with the manual and they seem to match. TB6 is not there, but, I think I would need to define some inputs for that to show up. 

Is it a reasonable conclusion that this means I'm probably good to go?

CLI Input:

Code:
linuxcnc /home/jdelaney/linuxcnc/configs/Rosie-01/Rosie-01.ini


Output:

Code:

In  ~/linuxcnc/configs/Rosie-01.pncconf there are loads of lines for pins. They don't seem to match the 7i95 board. They might match a 7i96. I am assuming if the board can be queried that the result over rides this file. Anyone know if that's correct?

I'll see what I can do from here.

Best,
John

The thread you initially referenced, later in the thread has some info regarding the pins.
forum.linuxcnc.org/27-driver-boards/3789...7i95?start=10#151528

If run your config, this assuming you are using axis, you can goto Machine ---> Show HAL Configuration and browse thru the headings on the left to see what pins are available.
