1.You need solder 3-pin connector on "Z_max" position(you can see the printed chars on the back of the board).
2.I didn't find the entrance to type in the Gcodes in Cura,and i'm afraid you have to use Repetier Host...

Did you fix it?I guess it is the firmware issue.

If you, as I do, have a GT2560 Rev.A and do not get comfortable soldering onto the GT2560, you can get the BLTouch to run by following this workaround:
1) Connect the black and white wires to Z-min as explained on the Geeetech wiki
2) Connect the brown and orange wires to two-pins socket where you should solder the three pins that is, to the right of the Z-min connector: the brown on the bottom pin and the orange on the upper pin (looking at the board with the USB connector facing downwards)
3) Connect the red wire to the available stepper socket: on the blue strip, second pinhole starting from below.

See attached picture.

That is what it takes on the hardware side. Now on the software side you have to activate "#define SERVO0_PIN 32". See Geeetech wiki for 3DTouch.

I have attached the Marlin version I adapted based on based on NiklasO (see NiklasOlofsson in GitHub) configuration I use in my printer for your reference. I have successfully compiled it with Arduino IDE 1.8.1.
