ohh a bit of time on google turns out bought ones are hideously expensive-!

so now am looking for some (i assume) zero backlash ballscrew in maybe a 16mm? was gonna do 20mm hiwin type with the carriages fixed and the rail sliding to give more slide,

so i figure i need a motor mount, a flexi couple, the ball screw support, the nut, the nut housing, and the end support?

whats the best pitch?, and will 16mm be ok-

also anyone know of a supplier that has decent drawings/ downloads available?

getting there- only problem is work getting in the way-!!
