@Phaedrux WOW! Awesome! it works. Thank you for your assistance, I learned a lot. I have much more to do but this portion now works. My configuration portion looks like this;

; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop '

; Z-Probe
M558 P8 H5 F300 T6000 R0.4 C"!zprobe.in" ;DIGITAL mode, NO/NC, delay, speed, used as axis endstop
G31 X0 Y0 Z-0.1 P600 ;X, Y, Z offsets, sensitivity/threshold

For now it stays digital until final tuning and try analog, thank you everyone.

@gtj0 Ok, cool - makes sense!

@Phaedrux
I am using the z probe input. Thank you, I will try your suggestions when i am in front of the machine tomorrow

Should i see some reference to the sensor in the status panel of GUI?

M574 X1 Y1 Z1 S0
M558 P8 I1 R0.4 F300 X0 Y0 Z0

Same;
i rechecked the wire connectivity and that it is properly oriented in the z probe port of the duet, all good (oh ya, and its wired to the digital part portion of the Piezo).
I turned down the sensitivity to see if it might be triggered prematurely, same. When i send the M558 code i receive 'Z probe 0 not found' , what should it be returning?

Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.0 (2020-01-03b3)
Its the newer version of the sensor, i have tried both sets of pins, right now using P8 on the M558. I will change the M574 to Z1 and see. thanks!

@Phaedrux said in Hypercube Piezo Orion - I dont understand...:

M558
Error: Z probe 0 not found

Homeall shown below;
In that last link i posted (from Piezo) it shows using P1, although the other examples show using 5 and 8 of which I tried as well.

So, I have had this Duet WIFI working outstandingly in another printer while it printed parts for its Hypercube replacement. I have this thing all assembled and am working toward making this Hypercube operate even more outstanding than its predecessor. If it were not for my simplistic understanding of the config...
X and Y endstops work great. I have a similar one for low Z that the board acknowledges (lights the LED on the board) but does not stop downward motion.
also, when homing X or Y the bed raises 3~ inches - the board finds its X or Y and then drops again.
When homing Z the bed raises a few inches (no where near the nozzle/piezo and then presents me with this;

Not sure why this happens, should not the probe define its location? I have read and tried a number of examples like these ones;

But every attempt seems the same. Please take a look at my config below, any pointers would be greatly appreciated.
