no safety on this one !

I'm interested in any ideas as to the test request above ?

I know electronics

I don't know the voltages involved with laser PSU's .. Will (google in a bit)
I almost seems as though they want me to wire up a thin piece of wood and see if I get an "Ignition Phenomenon"

I have a multi meter (1000v)... and lots of different value resistors .. could I rig up a quick test circuit to test if the laser PSU has an output ?

Have a look at this:- https://www.youtube.com/watch?v=Qz6J4Rs7VCw The voltage you are playing with is about 10Kv 10,000V So yes they are asking you to put a piece of wood in to see if it burns up ..Clive

ah !
It seems they sent me a wrong link to a video .. it just showed the machine cutting a smiley face !

After some google translate'ing and searching I found this ...

(You have to watch the ad' 1st)

I shall test and let them know the result :)

I thought they wanted you to use a piece of wood to push the wires together to short them and see if they spark. It's an amazing spark and pretty loud but not something I would do voluntarily.

I would examine other parts of the system first such as the enable laser button to make sure its working and the connections are solid.

ok , just finishing for tonight. rigged up the test as in the vid .. nothing

Does the test button on the PSU bypass all the safety features, like the water pump ?
I'll double check all the wiring in the morning, and try again

No, test button needs the other safety features to work :)
