W|W plasma/drag knife 1500x1500 (floating head & z-axis)

Floating head assembly.
WLOG (WIP)

• I had to use only parts I already have.
• Z axis and floating head should be extendable - I want to have possibility to replace plasma torch with drag knife or other tools when needed.

Some tests with markers.
