<blockquote>Homemade modified CO2 Laser-Cutter K40 (40 Watt):
Motivation for upgrading:
<li> bigger workspace </>
<li> air-assist</>
<li> opensource controller</>
<li> standalone device</>
<li> focus gauge</>
<li> Z-table</>

Project has finished now. Here are some details of my experiences:
<ul>
Workspace
bla bla bla.
aaa bbb ccc
</ul>



Controller: original Chinese-Japanese? m2NANO replaced by smoothieboard-X3
