Is there a list of things to check before powering on the laser the first time?

Seen some tips here and there, cheking cables, power, mirrors and other hints on what to look out for on the K40 lasers before powering it on and the first test.

A step-by-step on this matter would be nice, for others to find too.
Sorry if i missed one already existing, didnt find anything here though :slight_smile:
