Motivation for upgrading:
<li>
bigger workspace
air-assist
opensource controller
standalone device
focus gauge
Z-table
</li>


Controller: original Chinese-Japanese? m2NANO replaced by smoothieboard-X3
Workarea: expanded from (300 x 200 x 80) to (340 x 270 x 80 ) mm
Focusing added (double red-point laser with intersecting rays)
Air-assist added (pump from a blood-pressure gauge)
Software: Inkscape + LaserWeb3
