Why don't we have a (shallow) 3-D CNC?

Are "slopes" possible with Maslow?

So I’m thinking about a project that would involve shaping a piece of wood but am unsure if I can do the cutting as I would want it. Basically, will the maslow move from one x,y,z position to another x,y,z position linearly, including the z-axis, without issue? For example, if I want to cut from 0,0 to 5,5 and it slope down from 0 to .5 inches, the gcode command would be (I think) G0 X0 Y0 Z0 G1 X5 Y5 Z-0.5 F30 Would Maslow actually lower the z-axis linearly (i.e., straight line) through …

main issue is stock original z axis has too much play, you probably want to upgrade the z axis is this functionality is critical to things you want to cut.
