Duet Maestro Z_PROBE_IN pin name

[bwright85428]

Can anyone help me out figuring out what the z_probe_in pin name is? I know 51 is the logical pin number, but I am looking for the specific signal name like PA1.

Thanks
Brian

You can find the schematics here https://github.com/T3P3/Duet/tree/master/Duet2.

@dc42 I have went through the entire schematic multiple times and the only reference I can find to the Z_PROBE_IN is the header pinout. The only inputs I see are for Z_PROBE_MCU and Z_PROBE_MOD. Thanks for the reply

Z_PROBE_IN and Z_PROBE_MCU are connected together through a resistor on page 2 of the schematic, the page that shows the stepper driver and endstop circuitry.
