1rst build, time to do next step

[Gytis]

Don't need BK both ends, just at drive end. BF is fine for other end.

Hi Irving,

I almost sure that you are right, but it will be my first built CNC (so I'm trying to do my best as I can)
what I know about screw and ends?

only one,
fixed + fixed ends its much bater than fixed + floated
(it will eliminates wipping and increas the speed ?)

Thanks for input !
