Circles but not circles

Hello everyone: I hope someone had the same problem or give me some hints.

I was putting off for so long. Circles are not really circles. As you can see in the pix. The head starts at 3 o'clock (0°) and when it gets to 6 o'clock, Y axle gets fixed 24° (of the circle). The same occurs when the head gets at 12 o'clock.

X and A axle are 1:2 reduced, Y and Z 1:1

Mach3 configs

X and A axle: (reduced 1:2)
Steps per 28.766
