"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.

ttk buttons have no height or width configuration options so in this instance the easiest way is to add newlines and spaces around the text.
Something like the below inserted immediately before the return should look reasonable.
    after 0 {.__tk_filedialog.contents.f2.ok configure -text "\n          Open          \n"
             .__tk_filedialog.contents.f2.cancel configure -text "\nCancel\n"
            }

Making more progress on water table. If I was to ever building something like this again I would build a stronger support frame to on the inside and underside of the table. I kindof skimped out there and it lead to lots of steel warping and bowing. I don't think it will matter much because I am going to build slat frames that can be leveled. Hopefully it's strong enough to hold all the water and up to 1.5 inch plate. Seems to be to me.
