Z probe question
-
the webpage only updates in intervals. if the trigger happends between the interval, you will not see a change in the value.
-
If you click the switch with your finger and hold it down, it may show as 1000 for longer.
The important thing is that triggering the switch stops a probing move (G30). If it does that, it's working fine.
I do wish the probe display on the web interface would take the raw values the firmware gets and translated it into a more useful piece of info, like last triggered 10 seconds ago with value 1000. But that's more info than can fit into a small box.

Okay, that explains a lot
One thing though, why is the calibration so damn slow now after I changed M558 H30 to H35 in the config.g?
-
Is it possible to make the calibrations faster anyway?
-
What is your entire M558 command?
H30 versus H35 adds an extra 5mm of travel, so that will take longer. You can increase the dive speed perhaps or reduce the dive height, that's your two options for reducing the time taken.

; Z-Probe
M558 P8 C"zprobe.in" R0.4 H35
F1200 T5000 ; set Z probe type to unmodulated and the dive height + speeds
G31 P500 X0 Y0 Z13.90 ; set Z probe trigger value, offset and trigger height
M557 R175 S20 ; define mesh grid -
The calibration now does 2 mm / s

@holco62
its always a good idea to read the documentation as to what the parameters do.https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_Set_Z_probe_type
You are probably looking for the F parameter
-
Keep in mind that M558 F will still be limited by your max Z speed set by M203.
Since your trigger height is nearly 14mm using 35mm dive height is probably overkill. You really only need to lift high enough to ensure the probe is clear of the bed before probing again. M558 H20 should be enough.

Thanks for the feedbacks, I'm a bit wiser again
