3d touch z-probe problems
I have set-up a 3d touch (BL Touch clone) z probe on a ramps 1.4
I have followed the guide by "Pidgeon Print".
I am bench testing the set-up on a spare Ramps so nothing apart from the probe is connected.
When I power up the Ramps.. the probe does a self-test okay (the probe cycles in and out 2 times) and the red LED comes on.
However, I send the M340 P0 S700 or M340 P0 S1500 command and nothing happens.
I have tried the set-up on my printer and it does the same.
Any suggestions?

Also recheck if the value shave the meanings you think. I think the correct servo positions do not have such smooth values and if you are outside the recognition range nothing will also happen.
I have the three wire servo connector wired to Servo0 on the Ramps, I am assuming that I should select Digital Pin 11. The two end stop connection is wired to Z-min ground and signal.
I have checked and found other values for S so will try these as well.
It seems contradictory to have both configurations use Digital Pin 11 or is this correct?
For the record I have Z-min as electronic NC and Pin z-min endstop
Is there a way to test that a signal is being sent to the pin or a way of checking that I have communication to the pin?
M340 P0 S700 or M340 P0 S1500
That will not work. servo pin is 11, z probe pin is z min pin I think from your description. When you set it to 11 you make 11 an input so it is not controllable!
