@NedMan any objections to moving this to the Getting Started category?
Here are some pics showing the proper orientation of a plano-convex lens (curved side towards the laser) and the effect of different focal lengths.
K40 machines typically use Plano-convex lenses with a 50.8 mm (2") focal length as it offers a good balance with a small spot size for engraving and a reasonable depth of field (DOF) for cutting.

Similarly, we have two places with alignment help.
The one thing K40 owners Love to do is align their optical mirrors. Dropbox …
A K40 may require regular maintenance as part of initial setup because many are shipped with quality issues. Therefore, initial setup includes checking periodic regular maintenance items before you start using it.
Could we make the Getting Started post canonical, and unpin the other?
I think that pointing to @donkjr ’s stuff is great, and we should consider where in Getting Started a link to this stuff should go! Or is the better thing to scatter more specific links throughout annotated “for more information”?
@donkjr has a great blog where he documents all his musing on the total conversion of a K40.
