Determining Z probe offset x & y
I am unconvinced that I understand the correct manner to determine z probe offset x, and z probe offset y. I've seen multiple write-ups that seem to use entirely different coordinate origins, and the diagram in the Repetier Z Probe write-up shows the xy origin point centered between two extruders. I have a simple one extruder configuration, with an inductive probe mounted to the front and left of the extruder. My assumption had been that I merely needed to measure like this:
. - - - - E
|
|

P
Looking from above front, with E being extruder and P being center of Z probe. So, if we assume each dash or vertical bar is actually 1mm, the offset values would be:
z probe offset x: -4
z probe offset y: -3
That is, the total unsigned offset from the extruder to probe is 7.
Is this correct for Repetier? Or? ... Thanks!
