@droftarts hey's baaaaaaaaaccccccccckkkkkkk
I just moved the white wire on the 5 pin io2 connector from io2_out to io2_in, The green wire is still in the center of the connector / connected to GND.
Well that certainly should make a difference.
Please run the M119 tests with the Z endstop switch pressed and not pressed.

@droftarts @fcwilt M119 reported all of the axis are NOT STOPPED, WAIT A MINUTE!!!!!
6/27/2022, 9:28:48 AM M119 Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: not stopped 6/27/2022, 9:28:11 AM M119 Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stoppedLook at the timecode, between :11 and :48 Z changed!

@droftarts @fcwilt I knew there was a reason I named this machine Frankenstein's Cinderella.

So it seems like the Z endstop switch is now working?

@droftarts @fcwilt I turned off the machine, then turned it back on. M119 reports that Z is at min stop.
My finger isn't anywhere near it.
But, when I depress Z, and send M119, it says Z NOT STOPPED.
-
@droftarts @fcwilt Z needs to be reversed, doesn't it.

Just edit the M574 line for the Z endstop and add the ! character, save, re-boot and re-test with M119.
You see what X and Y endstops do.
You need to get Z doing the same.

@fcwilt @droftarts FREAKIN' SUCCESS!
With all of the endstops up, all of them are off, with Y endstop depressed, it is at min stop. with Z depressed, it is at min stop, and with X depressed, it is at MIN STOP!
-
@droftarts @fcwilt I wonder where that puts us?

Congrats.
Now that you know the endstops are working you can proceed to fine tune your homing code.
Because you have a Z endstop you can start with that.
One Z is homed then homing X and Y is a piece of cake.
How about doing one at a time.
Please post your Z homing code which should be in homeZ.g

OK that is code for homing with a Z probe.
Now that you have a working Z endstop you can use simpler code.
Something like:
G91 ; relative movements G1 H1 Z-250 F3600 ; fast move toward Z endstop G1 Z10 ; backup off a bit G1 H1 Z-15 F360 ; slow move toward Z endstop G90 ; absolute movements G1 Z10 F3600 ; move to 10mm off the bed to allow X and Y movementsFrederick

@fcwilt so you're saying I can copy and paste your suggestion into the homez.g, correct?
-

As long as you make sure none of the existing code is there.
Or you can rename the existing file if you want to save it.
And then create a new homeZ.g file and paste what I posted into it.

@fcwilt So, I copy what's there from G91 to G30, delete that, then copy your code to that space to replace what was there, correct?
Doing that preserves the first 4 lines of code, and the last 6 lines as well.

Well if you wish to preserve those 2 or 3 first lines, that's fine.
But you don't need any code other than what I posted.

@fcwilt I just concerned that if I delete everything, then paste your code into that blank space, I'll loose the ; homez.g (header)?
It's not that I don't trust you, I've just never done any coding.
-
@fcwilt okay, done
-
@fcwilt on to Y, X?
-
@fcwilt or should we test Z?
