Z Endstop not used
-
I have a working optical endstop that is lighting the LED on the DuetWifi and shows the correct state in the web gui. I believe that it setup correctly in the config (shown below) but when i attempt a print i get this;
and when I adjust the nozzle to the bed again it either dives into the bed or is way too far. shouldn't it use the X endstop that is setup?

Remove the endstop definition and define it as a probe instead. It will also act as an endstop.

I read to make it like this;
M574 Z0 S0 P"zstop" but that's not right -
I reused the calibrator and it came up with; but now using the z probe input? the unit never dropped to sense the endpoint and gave me the same manual option in the gui.

When using the Z probe to home Z, M574 Z0 should be used.
@soreloser, you need to get the Z probe working. See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_RepRapFirmware_Num_3.

The same condition with these changes, it still asks what the probe hight is and will not lower to check;
M574 Z0
M574 Z0 S1 P"zstop" -
So I purchased an inductive probe as I believed that the unit might have failed because it was not deploying the probe.
I followed the tutorial from here and the unit is powered and senses aluminum if I get it close to the tip of it;
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Connecting_different_types_of_Z_probe
The tutorial starts discussing the BLtouch so I moved on to this tutorial for testing;
https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
which says to send the G30 command to begin the calibration. once I do that I am presented with the same web GUI to manually adjust the gap until it is just touching. What am I missing here?; Configuration file for Duet WiFi (firmware version 3)

you have not defined which pin to be used. this is required in rrf3
-
In my endstop section it is listed there as P5. In the 'connecting z probe' doc it says;
5 Digital probe connected to Z Probe input HIGH during probing, LOW at other times
This is how it is connected to the board -
you might want to adjust that. because i believe in 3.01 it will not work anymore, as the default config is changed.
also you are missing the

Awesome, forward momentum!
I no longer get the popup but the unit does not drop and returns with;
The following axis is not homed: Z
I will read more and continue. thank you for your help -
@soreloser You may have to change your Z homing script. To home Z with the probe, move to the XY position where you want the bed to home, and use G30: https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_G30_Single_Z_Probe
This from @dc42 :
The related thing that some users get wrong is using a G1 S1 move to home Z instead of a G30 move. This combination of these 2 mistakes [setting M574 Z1 S2] will allow Z homing after a fashion, but of course the Z height will get set to the M208 limit instead of the Z probe trigger height.

I think i have it now and have setup a very good starting height that i now send a file to the printer and have confidence in a good first layer (all after reading the calibration doc). I plan to setup a probing mesh next and would like to thank you again for your help here. I did learn quite a bit.
