Peter,

On the one I did I used type 23's all round, the 180 Ncm or 250 oz / in ones, 3 amp drivers at 30 volts, direct drive on the X and Y and 2:1 belt reduction on the Z.

The 1/16" was taken off the underside of the bed to clear the nut block but different nuts may, or may not need this.

Been looking for some pics but can't find them, I know I took some of the bed having the channel being milled.

It worked very well for it's size, a lot faster than the Taig but then again the Taig was still on 20 tpi screws
