If i knew how much trouble this knockoff board is gonna cause me, i would have never bought it… Sadly its the only thing i have right now and i dont want to wait weeks to get another board.
Ok. So the issue is, the slicer/M119 code cant seem to detect if the probing-pin is up or down.
M280 commands move the pin up or down so wiring on that side, the 3Pin connector seem ok.
If i assign "zprobe.probe_pin" as p1.28, the Z-minus pin in the board and connect the 2Pin signal wire to it, the M119 command wont detect if the pin is up or down.
If i add "!" to the pin in the Config-file, the M119 command shows ALLWAYS "probe:1" and without the "!" ALLWAYS "Probe:0" regardless of where the probe-pin is, up or down. I did test pulling the wires off, with the "!" and "probe:1" always on it went to 0, so something does go thru the unit…

Look for "config vX.X" rar-file.
