One thing I've not seen mentioned, is how are the laser and arduino powered, and are they suitably connected?
If both are powered from the same 12V supply, they should already share a common ground, but if you're powering them independently (i.e. 12V to the laser, but relying on USB power for the Arduino), then you'll need to connect the Arduino ground to the laser/12V ground. Without that connection, the TTL/PWM control circuit won't be complete, and nothing will likely happen.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

Looking at different things, sometimes you realize that for everything you need a lot of money.

I'm curious....did you get chance to test the laser power? Does it manage to cut through 8mm ply in one pass?
