Linear scale is a measuring device linear in nature that outputs vaues OR signals that are used in measuring a comon signal is a quadrature output where there are 4 signals generated for each unit of movement. Basically same as a servo encoder but only it is linear not rotary.
It may be possible to have those ouputs Drive the Z axis motor movement up and down instead of directly from MACH3 It is called electronic gearing or slaving.
Yes the floating Z uses a mechanical platform mounted to Z in order for the cutter to follow the surface, not be controlled by the COntroller WHILE it is cutting.
Another thing about sonic sensors is the doppler effect of moving objects tends to distort distance measurements. Flying kerf and moving table may cause problems.
