    the probe works but when I do g30 s-1 the bed stays at a great distance from the nozzle as in the photoIMG_20211026_152856_edit_485625590903498.jpg

        If you move the bed away from the probe, say to Z=5, does then doing a G30 or a G30 S-1 result in the bed moving and triggering the probe?

                  OK so the probe IS working.

                  After doing a G30 or a G30 S-1 it is normal for the probe to end up a small distance away from the bed.

                  That distance is the dive height (the H parameter of M558) plus the Z Trigger Height (the Z parameter of G31).

                  Does that appear to be what is happening when you do a G30 or G30 S-1?

                      OK do this:

                      • Move to Z=5
                      • Execute a G30
                      • Carefully using the Z "jog" buttons on the DWC move to Z=0
                      • Check to see if the nozzle is just touching the surface of the bed

                          I see the Z reading is -1.00 - is that with the nozzle just touching the bed?

                              OK that indicates the Z Trigger Height parameter of the G31 is wrong.

                              If after doing a G30 and then moving to Z=0 if the nozzle is not just touching the bed you need to increase the Z Trigger Height parameter of the G31.

                              If the nozzle touches the bed before you get to Z=0 then you need to decrease the Z Trigger Height parameter of the G31.

                              Of course when you make a change to the G31 command it needs to be executed for that change to take effect.

                              When you have found the correct value for the Z Trigger Height parameter of the G31 then when moving to Z=0 after doing a G30 the nozzle should just touch the surface of the bed.
