Hi !
edit **** could you please give me your thoughts about the design and parts ? ******
i'm a newbie and this will be my first machine, so i'll probably have misconceptions, don't hesitate to correct me if i m wrong...
i been dreaming of a cnc for several years, now it't s time to make this real !
i've seen the 6040 on ebay but it's too small for me, what i want is a y=1500mm x=700 mm and z=100mm.
this dimensions can be increased if a standard dimension xy or z bigger than mine exists.
this is a simple drawing of the design.
Attachment 184988
the y ballscrew will be under the table
the x ballscrew will be between the 2 x axis supported rails.
it's a supported rails on supported rails design...
do you thinks diameters are good ?
