redesigning the x-axis

the x-axis had a slight deviation so i had to redesign this.

because i had a limit budget i used hollow-tubes wich slightly sack in the middle when pulled down by the weight of the router-head (2-3mm).
this way you get a slightly bended line when routing.

with redesigning i also had to do this with materials i already had because my budget for the machine was as good as fully spent.
i did buy a new rail profile in the hardware store but this only cost me 4€.
the rest is done with spare materials i already had.
