Very good Will and I'm looking forward to seeing the next part.
A few points:
The machine is shown as CE marked (for sale within the European Community as safe for purpose)
Initially I noticed two BIG holes in that...
There are no bonding straps between the moving doors and the main body of the machine,
The cabinet can be opened allowing access to the electrical components when under power,
The Tube cover can be opened when under electrical power giving direct access to both high voltage and radiation producing sources,
The guarding can be opened when the tube is lasing (no door interlock),
There are no radiation hazard warnings fixed to the case or work area,
The machine holds a plate saying laser engraving "Machine" (more on that in a minute).
That's just a few observations.
I just had a friend who is an HSE inspector watch the video, his only comment was "If you fit one of those in here I will shut you down"
The term "machine" for the purposes of CE requirements requires that "Machinery" conforms to both electrical and radiation hazard laws here for use in an industrial environment, this machine does not thus the CE marking is invalid (without it this equipment cannot be imported into an EU country legally)
UK HSE laws

without bothering to look at the numerous laws that this junk pile is in breech of it does beg the question "How are these kind of things permitted to be imported"
For personal use inside the EU it is likely people will get away with it, the problem is when people come to sell them, the penalties for selling non conforming machines include fines of up to £5,000 ($7,500) and 6 months in prison for each violation.
I've personally seen one case where a young lady was fined so heavily she lost her house (£150,000 in accrued fines) and had her equipment confiscated & destroyed.
If a supplier can outright LIE about CE conformance then that does beg the question...what else are they lying about?
cheers
