I have had the new toy for about a day and a half now. So far I have not been able to turn it on. Let alone get anything printed out. I need to add a water supply to keep the laser cool enough that it does not explode. Finding something that I can use as a container is currently defeating me. I need a closed container that will admit a submersible pump. So far, having done a tour round town, I have drawn a blank. I am currently think that maybe a fish tank or a home brew barrel might be the answer but these are not cheap. It would be almost cheaper to buy a ten litre paint can and throw the paint away and even then it's not got a seal around the cable.
There are no end of things wrong with it. This is apparently the way they are built. I still see it as better to buy a £400 laser that will require a little work than a £2400 laser that will work out of the box (but will still require a water container).
