M92 X100 Y100 Z100 E130 ; Set steps per mm
if all three (x,y,z) steppers use the same tooth count pulley, and the steppers all are the same type (for eg. 1.8 deg or 0.9deg per step) then the M92 X Y and Z values should be equal
After this is corrected then you can move on to the other two factor, the delta radius and diagonal rod length.
