Hi Rich
My Colchester master lathe is already converted to cnc but as a 4 axis mill i.e x,y,z,a using a vertical slide as y.
What I wanted was a simple explanation and possible parts to graft onto my BOB 6560 to make it more flexible and multipurpose.

PS I ask because I am not an electronic expert having bought a bob, power supply, and motors off ebay.
