You need result of all 40000000?

Typically you just have one track of holes and the B detector offset from the A detector by
hole_pitch*(N+1/4). That is, if the holes were 2 mm apart, the A/B detectors would be
spaced .50 MM or 2.50 mm or 4.50 mm etc.

This 1/4 pitch offset gives you the desired 90 degree phase difference between A and B.
Note the when drilling holes you should aim for a 50% duty cycle waveform
on A and B. This may require some experimentation and changing  the sensors
radial positions.

Why if i put in spindle shaft an aluminum disk with 2x100 holes(pi/2 equally spaced for A- and 1 hole for index drilled on the same mill?
I think i can do holes 1-1.5mm in the same mill accurately.

If you can get LInuxCNC running, I would first verify the home switch operation
with halshow.
