LinuxCNC + 3dPrinting setup + Stepcraft 420

Hello,
I ask help in setting LinuxCNC and 3D Printing Head 1.75
I figured out the correct LinuxCNC Setup based on hardware (stepper documentation, and shaft measurement).
Now it works perfect with attached setup.

Can You help me in setting up the printer head (leadscrew pith?, home?, pulley teeth?) for LinuxCNC. Maybe somebody, who knows the settings in MACH3.

My setting for LinuxCNC:
Motor steps per revolution: 200
Microstepping : 2
Movement / revolution 3 mm

This doc doesn't shows the value of the motor, neither the value of the shaft (perhaps it shows the value of the WinPC-NC movement - 400 steps / rotation means half step mode WinPC-NC )
