"Help" is a strong word for what's happening here.
You seem to be getting frustrated. Maybe I can help.
Correct me if I'm wrong, but your situation is that you have a Mesa 7i96s and Clearpath SDSK motors. You want to:
- Set some rational values for max velocity and accel
- Connect the HLFB pins to the 7i96s
- Make LCNC do something with the HLFB signals
Have I got it right?
Yes, and thank you for engaging.
Those points are just what are directly in front of me, right now. It's mostly because I am at the pncconf stage, and there isn't a selection for setting the pins for drive fault there. I am not hung up on moving on, as long as I know where I need to set this function. I have LinuxCNC forum people telling me they have no idea how Clearpath HLFB works and Teknic saying they have no idea how LinuxCNC works, and here I am, stuck in the middle. That's why I thought maybe seeing an existing configuration would skip the middlemen and I could just copy someone else's homework.
Beyond that, I also need to know what to expect when homing the dual-Y gantry axis. There is more I'd like to learn about autosquaring too, but that's just one thing out of a long list.
Some of these features will likely not be supported by pnccconf
It seems this post gives you some options for HLFB.

I think I would use servo-on and use a charge pump which I think pncconf supports
The drive error is connected to

Squaring the gantry is dealt with when homing
linuxcnc.org/docs/stable/html/config/ini-homing.html
Paired joints (eg your gantry motors) will have a negative HOME_SEQUENCE of the same value
Usually you will also use a HOME_OFFSET
You can square the gantry by editing the HOME_OFFSETS. eg if one side is out by 2mm, the HOME_OFFSET needs be 2mm different to the other side.
