Floating Z Axis

Sometimes we need to modify our CNC machine in order to achieve our machining goals as quickly and as efficiently as possible. CNC machines such as plasma, plotter cutters, lasers need mechanism that helps with measuring of material surface.

Good example of such modification is Floating Z axis.

The concept is pretty straight forward: Z axis has its own movable unit which is able to move when tool encounters with material surface.

You will also need:
6mm shaft for linear bearing, length 85mm, 2 pcs
LM6UU linear bearing, 4 pcs
35mm x 9mm x 0.7mm spring, 2 pcs (I found them in "spring assortment box")
Switch is Omron D2F01FL
