Hi Fernando. FWIW, I found that collimating with the coma corrector in place was best and that both mirrors needed to be adjusted. The other thing I found that helped was to round off the ends of the 3 secondary adjusting screws. Mine had sharp raised ends that cut into the surface of the hub and made fine rotation difficult - it is easier with the ends of the screws smoothed off.
