Sorry for the late reply.
I think that the problem is that you have never "addf"-ed the and2 function to a thread, so it never runs.

addsomewhere and it might start to work.

Just to divide 1600 by 5 = 320 steps/mm.

Do you have the steppers running? I am curious if that voltage level shifter works. I mean, it should work but I never came that far in my build.

I'm very interested in your solution, because I have the same setup and I'm trying to make it work.

I have ER20, non-repeatable collet and with every tool change need (want;)) to measure the tool tip. My tool setter is actually slightly below the worktable, and that lead me astray whether it's possible to make it work with Probe Basic native tool setting, since it requires (???) to know the distance of the shoulder of the spindle - I'm not sure.

I have a working tool setter in QTDragon via M6 remap and maybe that's the way to do it as well in Probe Basic. Any thoughts?

What is the mod as marked in the attached photo?
 

it lowers the voltage of the level shifters on the FPGA side to cope with the 1.8V on certain ports, is fixed in the current git for the board

What happened with enable and error hardware implementation in riocore?
 

what exactly do you mean?

You could try to create a new path /usr/share/linuxcnc/gladevcp/NativeCAM and follow the alternative instructions given up there by freemoore since he runs LinuxCNC on Debian.

This was helpful. I got the diodes and switches and took some pictures and built a little graphic:

I guess the thing that confused me was what exactly it's doing; checking for continuity? Like, "okay, I see a path through bit 0 to ground, but not through bit 1, so I recognize switch position 1, and now I will do what I am assigned to do when I see that scenario." Right? That wasn't a mystery so much as just needing to visualize it. It didn't help that there are exactly zero photographs of such a thing labelled as such in the wild, at least that I could find.

Again, thanks for the print. It was genuinely helpful.

Now I've got to figure out if Mux8 is worth taking up 4 inputs, instead of doing the resistor thing, for the mode selector switch. I just did a Google search for "LinuxCNC mode selector switch," and the pickings are slim. Here is a Fanuc-style mode selector switch taken directly from the console of the Mitsubishi M64s control I used to run on a 3-axis mill:

Obviously I don't need DNC, but I want to be able to access the rest of these modes with a hardware switch. That's my goal.
