z-axis calibration

Hi,

I am almost finished calibration of my Prusa i3 but I am not sure I understand how to adjust the height for each layer... currently I am using Repetier Host.

I am changing the Z-axis value in Configuration.h file in Arduino

eg.. #define DEFAULT_AXIS_STEPS_PER_UNIT {80.0000,80.0000,1000.0*8/3,800*1.1}

but I am wondering... should I only be changing the Cofiguration in Slic3r ?? So for example after I load my object stl file I can configure the thickness. temp etc.. within Repetier.

any help on this would be really appreciated

Best,
Michael ( I've been at it for two months now & am so close.. )

Z steps are calculated by the number of micro steps per revolution of the stepper divided by the pitch of the threaded rod .
M5 threaded rod has pitch of 0.8 mm and most steppers set at 16 micro steps will give 3200 steps per revolution.
3200 divided by 0.8 = 4000 steps per mm
And M6 is 1 mm pitch

M8 is 1.25 mm pitch.
