Default Re: lazer not burning

More than likely you either A have the wrong wires connected to power the burning side not reading side and B the laser would be focused to burn only very very close to the lens if you have got the right power leads you would need a lens of some sort to focus the laser further out rather hard to get something to burn if you have to hold it 1 mm or so from the lens

You should upload the images to some other server, like imageshack.us, and then just link them here.

Sounds like the wires are connected incorrectly, and it's not giving its strongest output.
