BLTouch not detecting
-
Hello! some issues withthe bltouch not showing any detection. Correct setup in config.g:
M558 P9 C"^zprobe.in" H5 F200 T6000
propper deployment and retraction of the probes solonoid through:
M950 S0 C"exp.heater3"
The wiring is correct and has continuity. Just isnt showing once the tip is drawn back after touching the bed. Anything helps!!!

What are you expecting to see? Where are you looking?
If you do the static test described here, does it work to stop Z movement?

In DWC; Dashboard; Status box; under Sensors; Z-Probe. The output of the probe does not change, ever. I can invert the signal by adding an "!" in front of the "^zprobe.in" and the signal will appear to have been inverted in the Z-Probe Status field. But really thats a superficial readout change. So, having run the static test and hoping that the Duet 2 WiFi board picked up the tip touching the bed is to no avail. This is the second BLTouch I've used/tested with. Swaped the Z-Probe and the GND signals too... nada. -
The probe status in DWC isn't updated fast enough to capture the very brief status change from the BLTouch since it resets immediately upon triggering.

So you're saying that it doesn't trigger to stop the Z axis when sending a G30?
In that case it sounds like your white signal wire is either not making a connection, or connected to the wrong place. Your config shows it should be on zprobe.in
Please post your full config.g, homeall.g, homez.g.
Also post the results of sending M122 and M98 P"config.g" -

Your homing files are set to use an endstop, not a probe.
G1 H1 Z-266.5 F6000 ; move Z down until the endstop is triggered
G92 Z-2.5 ; set Z position to axis minimum (you may want to adjust this)Replace those lines with something like
G1 X150 Y150 F6000 ; move the center of bed
G30 ; Probe the Z axis
