That should help a lot with damping vibrations, although i would have used metal in this case, more space to fill and heavier, but more work mounting stuff to it.
Nice work, do post more pictures, we like looking at them. :)

thanks Tom old mate! I agree that metal is better, but I don't have that tool, I would have to carry the construction to leveling.. this turned out really hard and heavy. I will post more pictures due to the lack of free time, I am limited to a couple of bolts per day:)
QUESTION FOR THE EXPERTS.. this will primarily work with smaller pieces of wood, and generally I will use the main head as the A axis, now during the operation it should also be used as the S command (spindle) so that the processed part will be cut by a classic knife. The drive motor is ac servo 1500rpm (encoder 10k ppr which can be divided into smaller ones in the driver) the plan is to use the head on stepdir command for the A axis. My question is essentially that llinuxcnc can read one stepgen both as A (index) and as S (full rpm) command at the same time? I know Mach3 can do it.
