I did a little bit of research before buying it on eBay, and expected problems, but had hoped that it just might do what I want out of the box. Unfortunately not!

Does this machine have the capability to engrave anodized aluminium? Reading around I was under the impression that anything above 30W could do this, but when I try to engrave anodized aluminium with this machine, all that happens is that the material gets incredibly hot. also reading around, I have found that the real wattage of the machine is quite a bit lower than 40W...

If the K40 out of the box is unsuitable, if I purchase a 35W tube from Lightobject, would this be enough to engrave anodized aluminium?

I'm also going to buy the DSP upgrade kit, even though Moshidraw is so good.
