      Hey Guys, i am struggling to get my bltouch working ( again ) and hope you can help.

      I configured the probe as follows :config.g

      ; Z-Probe
      M950 H3 C"nil"
      M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
      M558 P9 C"^zprobe.in" H5 F150 T6000 ; set Z probe type to bltouch and the dive height + speeds
      G31 P500 X20.14 Y29.88 Z1.5 ; set Z probe trigger value, offset and trigger height
      M557 X30:240 Y30:260 S40 ; define mesh grid

      When i power on the printer the probe does it's POST pin down and up thing.
      But I don't get any response from M280 P0 S10

      I wired the sensor this way : acede04a-e8b7-42ab-89da-a88cbf21a20b-grafik.png

      The BLtouch is an old version with metal pin. Strange thing is, on my other printer i have the same wiring and configuration but with FW Version 3.1.1 and the probe works flawlessly.

        Try switching to exp.heater7.

        Edit:

        M950 H3 C"nil"

        Is not neccesary for that release.
