How do you call the mechanism that allows linear motion along the Z-axis in a Cartesian 3D Printer?
I know what the individual parts are; it is a lead screw, a smooth rod ... but how do you call the mechanism that allows this linear motion?
Mechanism is defined as: an assembly of moving parts performing a complete functional motion, often being part of a large machine
So I guess, it has to have a name, doesn't? .. but I am unable to find it
