Hey, I got a Shapeoko 3, with the homing switches add-on.
What, uh, is the intended installation method? It's not in the install process, nor is there any ancillary documentation I've seen yet.
May be obvious, thanks for any help!
Where are the official instructions for home switch install?

Shapeoko 3 #192 - Complete! Needs limit switches.
Re: Where are the official instructions for home switch inst
Thanks! That install took me an embarrassing amount of double-takes and do-overs but all's good so far.
The Z-axis wire on mine seems WAY short, though. Like, if I thread it out of the top of the box created by the four stand-offs, it wont allow full range of movement. If I thread it out the left between the stand-offs, it works UNLESS it gets snagged on the corner of the protective box around the board. If that happens, it can prevent full range of motion (or break, I assume, haven't had to test that yet).
On the software side, I can now do the $h command, which is neat. However, if I jog the machine back into the switches, I can still bottom-out on all three axes -- how can these switches help prevent that?

They’re home, not limit switches.

FWIW, links to the instructions are on that page in the SO3 section.

Re: Where are the official instructions for home switch inst
Great, that's helpful, I have a lot to learn about all this.
So, I understand the differences between home and limit, I believe, but a few things still elude me:
-- Is there some way for Carbide Motion to "go home" by default, like when it starts up, finishes a job, or (perhaps most important for now) needs to change tools?
-- If I set Grbl configuration $20=1 in Carbide Motion, does that permanently set a soft limit at my home switches? Like, I won't be able to jog the machine past a point it cannot go?
-- Does that setting also start me towards working with work coordinate systems? or are there some other steps needed to get that going?
Thanks!'
EDIT: The z-axis wire length is definitely an issue. Looks like the instructions online use a white PCB while mine is a dark blue, and maybe the pins are located differently? It really just needs a few extra inches, but currently it's dangerous to let it run the full x-axis length, since it can snag on just the corner of the protective box and yank the wire quite hard.
