yea thats why i had to use the foam to hold it up, the beams were hitting the floor, the scanning angle is massive!!! make sure you get plenty of pics behind the cover, i don't want to open mine up yet but looking through the hole where the laser comes through, there appears to be a good green module, very well heatsinked, and i can't really see the red module, so get plenty of pics, i want to see what's inside this thing! one question, does yours make very much noise? the top panel seems to rattle a bit on mine?
