I realize this is off topic slightly but here goes for those that
are thinking of going down this path for making boards etc.
The one I got had been imported by an Australian Engraving/Screen
Printing Firm and the engraver who owned it before me couldn't get it
to work properly (he said he wasn't a computer literate as he needed
to be) so I got it for a good price I repaired the 10 turn power
control pot and it worked nicely.
The things you need to watch out for is the packaging as the tube
is fragile and I have heard of them arriving broken and the mirrors
not being aligned also all the connectors in mine were hot glued also
due to a transport issue earlier on in the distributors history.
CNCZone has a long thread that's worth a read as it follows some
of the trials a tribulations of several of the different versions of
the Chinese Laser instruments.
Like most of these things you get what you pay for but if you know
what you are doing or are prepared to learn you can tweak it to make
it work quite well.
One thing to be aware of is there are very few if any safety
interlocks on the cheap ones so you use it with care and don't let
children loose unsupervised the tubes are also water cooled so there
is an added complication of a bucket of water with a modified water
feature pump involved in the proceedings
When buying one 2nd hand you need to make sure you get all the
bits, mine included the Ventilation Fan, Water pump, software and MOST
IMPORTANT the USB dongle to make it work and a power board and some
sample items (essentially it was complete) I was very pleased for the
$1500AU I paid it was less than 6 months old and new at the time it
should have cost nearly $3000.
Anyone needing more info can contact me off group unless the
Moderators think this is still close enough to being on topic.

Stephen
