Z Probe: Switch / add explicit option for inductive probes NO & NC

[chrishamm]

So are you talking about these two probe types? https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_NPN_output_normally_open_inductive_or_capacitive_sensor I guess I could add support for them although you are actually the first one who requests this :-)

The Z-probe measurment that is compared with the trigger threshold is usually filtered, so the value can actually make a difference depending on the selected probe speed. I guess 500 is a good starting value though. Besides it's been part of the first-generation config tool and it is still used in the template of the second version, so I'd rather leave it in there.

yes - I'm using NPN inductive probes and they only give me a digital input signal - high or low. No need to use the analog measurement here.

Thinking about it some more, there is also the next section "Endstop configuration", which again has Z config options... not sure if or how this should be combined: Z-probes vs. Z-endstop.

My point was simply, that it wasn't obvious to me which config I have to choose.
In my manually written config files, I am using:
M558 P4 H3 F400 T7000 ; Use E0_STOP as inductive-NPN probe, fast and
M558 P4 H3 F50 T7000 A3 ; Use E0_STOP as inductive-NPN probe, slow, multi-probe
in my macros and homing files.

Is this still up for debate? I would be interested in such a functionality, as I'm not that confident with those config files and what I have to change where manually…
