      So using G32 after a successful homing of x, y, z the Railcore 2 300ZL results in the error message:
      "Z probe not triggered during probing move". However, I can see the BL Touch probe being triggered. What do I need to do to fix this error message? Also what commands control the speed of the Z-axis moving up during probing? Thanks

      my config files can be found here: https://forum.duet3d.com/topic/24328/bltouch-and-railcore-300zl-problems

        However, I can see the BL Touch probe being triggered.

        Has it ever worked?

        When the probe appears to function but the Duet does not respond it suggests the for some reason the signal from the BLTouch is not getting to the Duet.

        See below - the F and T parameters deal with speed:

          When I run the M280 P0 S90 the BLtouch retracts and vice versa with S10. Does this mean the probe is connected to the duet?

            That means the probe is getting power and getting the signal from the Duet to deploy/retract - that is via the three wire connection.

            It does not mean the signal from the probe is getting to the Duet - that is the two wire connection.

            From your config file:

            M558 P9 X0 Y0 Z1 H5 F50 T6000 A5 S0.02 H5 ; Bltouch probe type
G31 X3.0 Y40.8 Z2.104 P25 ; Probe offsets

            In the M558 you have X, Y and Z parameters - that are obsolete and not used with v3 firmware. You also have H5 twice, once is enough.

            But you are missing the C parameter which specifies the input connection. The is likely the reason it is not working as desired.

              My current config files are different it turns out. How do I display them so I can paste them here? Also should I take out wifi info? From my current config.g file I have these lines:

              M558 P9 C"^zprobe.in" H5 R1 F50 T6000 A5 S0.02 ; RRF3 BLTouch connected to Z probe IN pin

              G31 X-4 Y-42 Z2.65 P25 ; Customize your offsets appropriately - do a paper test, and put the probed value in the Z value here

                  Well that looks better.

                  If that is not working then I would check the wiring from the probe - as I recall it was a black and white pair of wires.
