To get information about the pin functionality you need to look at the man page of the specific component which can be found here:
linuxcnc.org/docs/html/man/man9/


For example the 'motion' component:
linuxcnc.org/docs/html/man/man9/motion.9.html

or the 'pid' component
linuxcnc.org/docs/html/man/man9/pid.9.html

Where I work right now it's pretty lean ( thanks to the new tariffs ) so I wont be messing with ours unless
we have a really good reason to need it. That said I wish you luck on your project.

Thanks for your input Mark.

Excuse my ignorance, but I assume the SS refers to the RS-422 serial connection?

Love your channel by the way. Digging the engine build. The John Britton diy way must run deep, and rightly so.

Well, I have been trying for a couple of hours to get this to work.

Not sure just what should be in gm.hal versus gmoccapy_postgui.hal.

Can someone please post a working solution for both hal files ?

John.

Yes, I’ve had a look at the link.
I’m sorry I didn’t explain my problem clearly before.

My main issue is figuring out how to correctly connect the components to, for example, make a motor turn.
I’d like to understand which signals and pins are needed and what their actual roles are.
Take the position signal, for example — in my setup, I’m using encoders, so they should be providing that signal.
What I’m looking for is a resource that explains where these signals come into play and what their specific purpose is in the system.

Thank you for your answers. After consideration, I'm currently considering buying an industrial PC with resistive touch screen from a really good Chinese company. They even have a cute version with buttons for feed hold/start/stop/e-stop and even feed/speed knobs attached to the panel. They said people have build LinuxCNC systems with their hardware, as well as with Ethercat.

The 7i97T has one SS configured on a connector, but with two S devices (7i73 and 7i84) you will probably need to flash a firmware with an additional SS port on the DIL connector.

Linuxcnc will open anything. you can even teach it to not complain about .NC files by editing your .INI file

I vote for that to be in Master as well.

When I hook a multimeter up to the vfd 10v in, the voltage physically drops near to Zero if a lot of speed adjustments are done. So I can see now what is happening but iv no idea why the voltage drops so much. It must be something to do with how remora outputs the signal ? 

I spent the whole day going through different code with chatgpt and still nothing, it's still dipping. Should I ask this in a general new topic in the forum or is this specific to remora do you think 

That's already the right direction, but I'm more interested in the commands like:
"net joint.0-pos-cmd <= joint.0.motor-pos-cmd"
These are the commands I would like to understand!

Have you actually looked at the linked document?
You need to understand the difference between a 'signal-neme' and a 'pin-name' See section 1.4.
