I've got an annet A8 style printer and have recently been trying to set up autoleveling using a bltouch sensor and repetier firmware.
I'm using a ramps 1.4 board.
I initially tried installing the bltouch using the servo jumper to power the solenoid but this caused damaged by ramops board.
I now have it sdet up with 5v from the psu as in the diagram second from the top here, labelled "RAMPS1.4 + External(additional) 5V power Wiring":

It seems to work now and I can control the raising and lowering of the probe using
M340 P0 S1500
and M340 P0 S700
however, when I run G31, I always get a low signal, I've tried using different endstop settings but it dosn't seem to make any difference.
Not sure if the probe was damaged with the rest of the board, I think this was due to drawing too much current from the arduino powering the solenoid directly.
Currently, I have the bltouch on the zmax pin on the board, I have the zmin and zmax pinouts switched in pins.h as I moved the z endstop to the max position (edit physical max position, so now the printer homes to z-max on the endstop, but the switch it hits at z max is plugged into the zmin, leaving the zmax available for the bltouch) and found that easier than moving the jumper. My configurations.h is attached.
