Re: [CAD_CAM_EDM_DRO] DIY Router Design questions ?

Scott,

well, it is only 20" wide, and it runs on THK
linear rails which are very stiff with zero play
in them, so as long as everything is tight it
should never skew. It is driven from the
bottom by a ballscrew, mounted in the center
of the table.
