Z height probe before print starts

[andornot]

Please can somebody tell the command to measure and set the z height with the z probe before the prints starts, i only want to measure the center (x0,y0) so i can add the command in the start gcode of the print.

To be clear, G30 probes starting from the current XYZ position. So you probably want to use a command such as G1 X0 Y0 Z5 F6000 immediately before it.

the G30 has a parameter for X and Y to define the point of probing. Can this not be used as well?

so is the command G30 S-3 to set the z height before the print?

No, just G30.
