Phrozen Sonic Mini 4k - First dry run test of the twin rail and base stiffener mods

I am in the process of upgrading my Phrozen Sonic Mini 4k because of the engineering issues this machine has. This is the first test of the new arm, the stiffened aluminum base and the twin rail z-axis. Suffice it to say the z-axis deflection is gone. Next to start printing with it to see how print quality is.
