Re: [CAD_CAM_EDM_DRO] Re: Shopbot, Rack and Pinion, Ball Screw, Acme precision screw?

Wes,

For my 2' by 2' cnc router, I use the 5/8" screw with 4 turns per inch.

For my 2' by 3' I use the 3/4" screw.

On my Z axis, I use the 1/2" screw.

I can give you the part number is you wish.

Bob Campbell
